NOTICE!The storage temperature for your unit is from -4 degrees to +167degrees Fahrenheit (-20 degrees to +75 degrees Celsius). Extendedstorage in temperatures higher or lower than specified will damage theliquid crystal display in your unit. This type of damage is not covered bythe warranty. For more information, contact the factory's CustomerService Department or your local service center.

INSTALLATIONMOUNTINGInstall the Optima in any convenient location, provided there is clearancebehind the unit when it is tilted for the best viewing angle. Holes in thebracket base allow wood screw or through-bolt mounting. You may needto place a piece of plywood on the back of thin fiberglass panels to securethe mounting hardware. Make certain there is enough room behind the unitto attach the power and transducer cables.

The Optima's gimbal bracket will also accept the GBSA-1 swivel bracketadapter that lets you rotate the unit a full 360°.

The smallest hole that allows one power or transducer connector to passthrough is 3/4". After the hole is drilled, push the transducer connector upthrough the hole first, then drop the power cable down through it.

POWER CONNECTIONSThe Optima works from a twelve-volt battery system. For the best results,attach the power cable directly to the battery. You can attach the powercable to an accessory or power buss, however you may have problemswith electrical interference. Therefore, it’s safer to go ahead and attach thepower cable directly to the battery. If the cable is not long enough, splice#18 gauge wire onto it. The power cable has two wires, red and black. Redis the positive lead, black is negative or ground. Make certain to attach thein-line fuse holder to the red lead as close to the power source as possible.For example, if you have to extend the power cable to the battery or powerbuss, attach one end of the fuse holder directly to the battery or power buss.This will protect both the unit and the power cable in the event of a short.The Optima requires a 3-amp fuse.

IMPORTANT!Do not use this product without a 3-amp fuse wired into the power cable!Failure to use a 3-amp fuse will void your warranty.

If you’re installing a speed/temperature sensor, read it's mounting instruc-tions. Route the sensor’s cable to the Optima's power cable and plug it intothe connector marked “SPEED/TEMP CABLE”

After the cables have been routed, fill the hole with a good marine sealingcompound. Offset the bracket to cover the hole. Route the power cablethrough the slot. Break out one of the holes in the back of the bracket forthe transducer cable.

SPEED/TEMPERATURE SENSORSThe Optima accepts up to three temperature sensors which can monitorsurface water, live well, air, and virtually any other temperature. You doneed to be careful when purchasing the temperature sensors, however.Each temperature sensor has its own "address". The sensors are labeled"Water", "T-2" (or Temp-2), and "T-3" (or Temp-3). If you want two (ormore) temperature readings, you'll need to use the proper sensors. Forexample, you can't use two T-3 sensors. The sensors that will fit the Optimaare:

TS-1BK One sensor for "Water" temperature display.

TS-2BK One sensor for "T-2" temperature display.

TS-3BK One sensor for "T-3" temperature display.

TS-12BK Two sensors for "Water" and "T-2" temperature displays.

ST-TBKOne speed sensor and one temperature sensor for"Speed" and "Water" displays.

You can combine these sensors in many combinations. See the list on thefollowing page for temperature and speed sensor combinations.

MENUSThe Optima uses menus extensively to guide you through the functionsand features of the unit. To use the menus, simply press the MENU key.The options on the menus let you to customize the unit to your particularneeds and water conditions. Use the up and down arrow keys to move todifferent menus. The left and right arrow keys select and adjust menuitems. If you ever get lost in a menu, simply press the EXIT key. This clearsthe menus from the screen.

MODESThe Optima has five modes: Fastrak™,digital/chart, split-chart, full chart, andwindow groups. To select a differentmode, simply press the MODE key. Ascreen similar to the one at right ap-pears. Press the up or down arrow keyto select the desired mode, then pressEXIT key to erase the modes menu. Asummary of the modes starts on thenext page.

OPERATIONPOWER/LIGHTSTo turn the Optima on, simply pressthe PWR key. A screen similar to theone at right appears.

The PWR key also controls the lights.Once the Optima is turned on, pressthe PWR key to turn the lights on.Press the PWR key again to turn thelights off.

To turn the Optima off, press and holdthe PWR key while a "countdown" appears on the screen. The unit will shutitself off when the countdown reaches zero. Release the PWR key.

8

Full ChartThis is the default mode used whenthe Optima is first turned on. The bot-tom signal scrolls across the screenfrom right to left. Depth scales on theright side of the screen makes it easyto determine the depth of fish, struc-ture, and other objects. The line at thetop of the screen represents the sur-face. The bottom depth shows at thetop left corner of the screen. The word"AUTO" at the screen's top centershows that the Optima is in the auto-matic mode, freeing you from sensitiv-ity, range, and noise rejection adjustments.

Split ChartA split chart shows the underwaterworld from the surface to the bottomon the right side of the screen. The leftside shows an enlarged version of theright side. The zoom range shows atthe bottom of the screen. In this ex-ample, the zoom range is 2X, or twotimes the right side's view. By pressingthe ZOUT and ZIN keys, you canchange the left side's zoom from 2X to4X and back.

FASTRAKThis feature converts all echoes to shorthorizontal lines on the display’s far rightside. The graph continues to operate nor-mally. FASTRAK gives you a rapid updateof conditions directly under the boat. Thismakes it useful for ice fishing, or whenyou’re fishing at anchor. Since the unit is notmoving, fish signals are long, drawn outlines on a normal chart display. FASTRAKmakes a useful addition to fishing at a sta-tionary location.

CAUTION!All depth alarms and automatic features are turned off when the Fastrakfeature is turned on!

9

Window GroupsYou can change the displays on theOptima by using the windows feature.This lets you use different displays foryour own fishing or boating situations.This feature gives you 8 different dis-play screens in the window groupsalone.

The screens available in the windowsmode are divided into two or morewindows per screen. Each screen ofwindows is called a “group”. Group “A”as shown above has the digital depthdisplay in one window, battery voltagein another, water temperature, speed,and distance travelled.

To use the windows feature, first pressthe MODE key. A screen similar to theone shown at right appears. Highlightthe "Group" menu at the bottom of thescreen. Now press the left or right arrowkeys to sequence through the availablegroups. When the desired group ap-pears, press the EXIT key to erase themodes menu.

Digital/ChartThe digital/chart shows the chart onthe right side of the screen. The leftside has four digital boxes containingthe water depth at the top of the screen,boat speed, distance travelled (log),and surface water temperature. At thebottom of the screen is a temperaturegraph. (Note: Speed, distance, andtemperature displays require a speed/temperature sensor which must bepurchased separately.)

10

AUTOMATICWhen the Optima is first turned on,the Automatic feature is enabled. Thisis indicated by the word “AUTO” at thetop of the screen. The Automatic fea-ture adjusts the sensitivity and rangeso the bottom signal is displayed in thelower half of the screen at all times.

To turn Automatic off, first press theMENU key, then press the up or downarrow keys until the "AUTO" menuappears. Press the left arrow key toswitch to the manual mode. The letters “Man” appear at the top of thescreen, indicating the unit is in the manual mode. To turn Automatic on,repeat the above steps to get the auto menu, then press the right arrowkey.

SENSITIVITYThe sensitivity controls the ability of the unit to pick up echoes. A lowsensitivity level excludes much of the bottom information, fish signals, andother target information. High sensitiv-ity levels enables you to see this detail,but it can also clutter the screen withmany undesired signals. Typically, thebest sensitivity level shows a goodsolid bottom signal with Grayline andsome surface clutter.

When the Optima is in the Automaticmode, the sensitivity is automaticallyadjusted to keep a solid bottom signaldisplayed, plus a little more. This givesit the capability to show fish and otherdetail.

However, situations occur where it becomes necessary to increase ordecrease the sensitivity. This typically happens when you wish to see moredetail, so an increase in sensitivity is indicated. The procedure to adjust itis the same whether the unit is in the automatic or manual mode.

To adjust the sensitivity, press the MENU key, then press the up or downarrow keys until the "SENS" menu appears as shown above.

11

The sensitivity menu has left and right arrows, plus a horizontal bar graph.The graph gives a visual indication of the sensitivity level. The number tothe right of the bar graph shows the percentage of sensitivity in use.

To increase the sensitivity level, press the right arrow key. As you pressthe key, the menu’s bar graph will grow wider and the percentage willincrease in value. You can also see the difference on the chart record asit scrolls. When the sensitivity is at the desired level, release the key.

To decrease the sensitivity level, press the left arrow key. The bar graphand percentage will decrease. When the sensitivity is at the desired level,release the key. When you reach either the maximum or minimum limit, atone sounds.

To erase the menu, press the EXIT key.

RANGE - AutomaticWhen turned on for the first time, theOptima automatically places the bot-tom signal in the lower half of thescreen. This is called Auto Rangingand is part of the automatic function.Typically, the range cannot be changedmanually while the unit is in automatic,as shown at right. However, depend-ing upon the bottom depth and thecurrent range, you can change therange to a different depth. In the ex-ample screen shown below, the bot-tom depth has descended to a point where you can change the range to150 feet. To do this, simply press the right arrow key while the Auto Rangemenu is displayed. When you're fin-ished with this menu, press the EXITkey to erase it.

RANGE - ManualThe Optima gives you complete con-trol over the range when it’s in themanual mode.

To change the range, first make cer-tain the Optima is in the manual mode.Next, press the MENU key and the upor down arrow keys until the range

12

menu appears as shown at right. Pressthe left or right arrow keys to decreaseor increase the range. The availableranges are 0-5, 10, 20, 30, 40, 60, 100,150, 200, 300, 500, 800, and 1000feet. After the desired range is dis-played, press the EXIT key to erasethe range menu.

NOTE: The depth capability of theOptima depends on the transducerinstallation, water and bottom condi-tions, and other factors.

ZOOM“Zooming” the picture is a common method used to enlarge small detail andfish signals. The Optima gives you two different zoom sizes, plus a splitscreen zoom option. The zoom operation and adjustment is different in theautomatic and manual modes.

ZOOM - AUTOMATIC MODEThe only way to zoom the screen in automatic mode is to simply press theZIN (zoom-in) key. This enlarges all echoes on the screen to twice theirnormal size. If you press the ZIN key again, the screen is "zoomed" to fourtimes normal size. To return the screen to 2X or normal, simply press theZOUT (zoom-out) key until the desired zoom appears. When the Optimais in the 2X or 4X zooms, "2X" or "4X" appears in the lower right corner ofthe screen, showing the current zoom mode.

NO ZOOM 2X ZOOM

13

ZOOM - MANUAL MODEThe Z-IN (zoom-in) and Z-OUT (zoom-out) keys enlarge and reduce thesize of the echoes on the screen when the unit is in the manual mode, thesame as the automatic mode.

However, you can manually adjust thezoom when the unit is in the manualmode. To do this, press the MENUkey, then press the right or left arrowkeys until the "CHART ZOOM" menuappears. Now press the right arrowkey. A screen similar to the one at rightappears.

This is the split-screen zoom menu. Azoom bar shows at the far right side ofthe screen. All echoes between thetop and bottom of the zoom bar areshown on the left side of the screen. Pressing the up or down arrow keysmoves the zoom bar up or down. As you adjust the zoom bar, the rangechanges on the left side of the screen at the same time.

To return to the full-screen mode, simply press the EXIT key. This alsoerases the zoom bar and move zoom menu.

GRAYLINE®

GRAYLINE lets you distinguish between strong and weak echoes. It“paints” gray on targets that are stronger than a preset value. This allowsyou to tell the difference between a hard and soft bottom. For example, asoft, muddy or weedy bottom returns a weaker signal which is shown witha narrow or no gray line. A hard bottom returns a strong signal whichcauses a wide gray line.

If you have two signals of equal size, one with gray and the other without,then the target with gray is the stronger signal. This helps distinguishweeds from trees on the bottom, or fish from structure.

GRAYLINE is adjustable. Since GRAYLINE shows the difference betweenstrong and weak signals, adjusting the sensitivity may require a differentGRAYLINE level, also. The level chosen by the Optima at power on isusually adequate for most conditions. Experiment with your unit to find theGRAYLINE setting that’s best for you.

To adjust the GRAYLINE level, press the MENU key, then press the up or

14

down arrow keys until the GRAYLINEmenu appears. A screen similar to theone at right appears. Press the leftarrow key to decrease the gray level orthe right arrow key to increase it. Thepercentage of GRAYLINE in usechanges as the arrow keys arepressed. The bar chart also gives agraphical indication of the GRAYLINElevel. You can see the change on thescreen (both on the menu and on thechart record) as you press the keys.After you’ve finished, press the EXITkey to erase the menu.

CHART SPEEDThe rate echoes scroll across the screen is called the chart speed. It’sadjustable by first pressing the menu key, then pressing the up or downarrow keys until the "CHT SPD" (chart speed) menu appears as shownbelow left. Increase the chart speed by pressing the right arrow key ordecrease it by pressing the left arrow key. The percentage of chart speedin use changes as the arrow keys are pressed. The bar chart also gives agraphical indication of the chart speed. You can see the change on thescreen (both on the menu and on the chart record) as you press the keys.After you’ve made the adjustment, press the EXIT key to erase the menu.

CHART SPEED MENU CHART STOP MENU

To stop the chart, press the menu key, then press the up or down arrowkeys until the "CHART" menu appears as shown above right. Press the leftarrow key to stop the chart. To start the chart again, press the right arrowkey.

15

FISH IDThe Fish ID feature identifies targets that meet certain conditions as fish.The microcomputer analyses all echoes and eliminates surface clutter,thermoclines, and other signals that are undesirable. In most instances,remaining targets are fish. The Fish ID feature displays symbols on thescreen in place of the actual fish echoes. There are four fish symbol sizes:tiny, small, medium, and large. These are used to designate the relativesize between targets. In other words, it displays a small fish symbol whenit thinks a target is a small fish, a medium fish symbol on a larger target, etc.

The microcomputer is sophisticated, but it can be fooled. It can't distinguishbetween fish and other suspended objects such as trotlines, turtles,submerged floats, air bubbles, etc. Individual tree limbs extending out-wards from a group of limbs is the hardest object for the Fish ID feature todistinguish from fish.

You may see Fish ID symbols on the screen when actually, there are nofish. Practice with the unit in both the Fish ID mode and without to becomemore familiar with the Fish ID feature.

When the Optima is turned on, theFish ID feature is automatically turnedon, also. To turn the Fish ID feature off,press the menu key, then press thearrow keys until the FISH ID menuappears. Press the left arrow key toturn the fish ID feature off. To turn theFish ID feature on again, repeat theabove steps, but press the right arrowkey until the "ON" is highlighted. Anytargets the microcomputer determinesare fish will be displayed as fish sym-bols.

Remember, the Fish ID feature can’t be used when the Optima is in themanual mode. If you turn the Fish ID feature on when the Optima is inmanual, the microcomputer will turn the automatic feature on. If you turnautomatic off when the Fish ID feature is on, the Fish ID feature will beturned off also.

FISHTRACK™The FishTrack feature shows the depth of a fish symbol when it appearson the display. This lets you accurately gauge the depth of targets. Thisfeature is available only when the Fish ID feature is on.

16

When the Optima is turned on, FishTrack is enabled. To turn the FishTrackfeature off, press the menu key, then press the up or down arrow keys untilthe FISH ID menu appears. Now press the left arrow key. Pressing it onceswitches the FishTrack feature off, but leaves Fish ID on. To turnFishTrack on, press the right arrow key, which highlights the "TRACK"label on the Fish ID menu.

CHART SETUPThe Optima lets you customize the chartscreen. To do this, press the MENU key,then press the up or down arrow keys untilthe "CHART SETUP" menu appears. Nowpress the right arrow key. The screenshown at right appears.

The digital depth display at the top leftcorner of the screen normally shows inlarge numbers. You can change this tosmaller numbers or turn it off completelyusing the "Show Digital" menu at the top ofthis screen.

You can also turn the temperature, speedometer, distance log, zoom bar,zone alarm bar,or cursor on or off using this menu. See below for moreinformation on these items.

CHART CURSORThe Optima has a chart cursor that allows you to pinpoint a target’s depth.The cursor is simply a horizontal line that extends across the display fromleft to right. A depth box at the end of the line on the right side shows theline’s depth. In the example at right, thecursor (line) is at 29.8 feet.

To display the chart cursor, highlight the"Show Cursor" on the "Chart Setup" menu,then press the right arrow key. A screensimilar to the one at right appears. Usethe up and down arrow keys to move thecursor up or down to the desired depth.

To turn the chart cursor off, repeat theabove steps. The Optima returns to thesonar screen without the chart cursor.

17

DISPLAY ZOOM BARWhen the unit is in the split-screen zoommode, the zoom bar doesn’t normallyshow on the screen. The zoom bar showsthe section of water on the right side of thescreen that is being enlarged on the leftside. To turn the zoom bar on continu-ously when the split-screen mode is on,highlight the "Show Zoom Bar" on the"Chart Setup" menu, then press the rightarrow key. Now press the EXIT key. Ifyou're not in the split-screen mode, changeto that mode. A screen similar to the one above appears.

To turn the zoom bar off, repeat the above steps.

DISPLAY ZONE BARThe zone alarm has a range bar. Anyechoes that appear between the top andbottom of this bar triggers the zone alarm.This bar normally doesn't show on thescreen. To turn the zone bar on continu-ously, highlight the "Show Zone Bar" onthe "Chart Setup" menu, then press theright arrow key. Now press the EXIT key.A screen similar to the one at right ap-pears. To turn the zone bar off, repeat theabove steps. See the Alarms section formore information on the zone alarm.

DIGITAL SONARWhen the Optima is first turned on, the digital depth display is located at thetop left corner of the screen. This display comes from a separate digitalsonar built into the unit. It displays only the bottom depth. If it loses thebottom, the last known depth will flash on the display. When the digital findsthe bottom, it will automatically display the bottom depth again. The digitalsonar can be turned off, however this also turns all automatic features offalso, such as auto sensitivity, auto ranging, and the Fish ID. feature.

To turn the digital off, first press the MENU key, then press the up or downarrow keys until the "DIGITAL SONAR" menu appears. Press the left arrowkey to turn it off.

Note: Turning the digital sonar off also turns the automatic mode off,including Fish ID, and the depth alarms.

18

ALARMSThe Optima has three different types of sonar alarms. The first is the FishAlarm. It sounds when the Fish I.D. feature determines an echo or groupof echoes is a fish. Another alarm is the Zone Alarm which consists of a bar.Any echo that appears inside this bar triggers this alarm. The last alarm iscalled the Depth Alarm. Only the bottom signal will trigger this alarm. Thisis useful as an anchor watch, a shallow water alert, or for navigation.

To adjust an alarm, first press theALARM key. The screen shown atright appears. Follow the instructionsbelow for setting each alarm.

DEPTH ALARMSThe depth alarms sound a tone whenthe bottom signal goes shallower thanthe shallow alarm’s setting or deeperthan the deep alarm’s setting. Forexample, if you set the shallow alarmto ten feet, the alarm will sound a toneif the bottom signal is less than tenfeet. It will continue to sound until the bottom goes deeper than 10 feet. Thedeep alarm works just the opposite. It sounds a warning tone if the bottomdepth goes deeper than the alarm's setting. Both depth alarms work onlyoff the digital bottom depth signals. No other targets will trip these alarms.If you turn the digital off, the depth alarms will be inoperative. These alarmscan be used at the same time or individually.

To adjust the shallow alarm, highlightthe "Shallow Depth" label. To adjustthe deep alarm, highlight the "DeepDepth" label. Both alarms adjust iden-tically. We'll use the shallow alarm asan example. Highlight the "ShallowDepth" label, then press the right ar-row key. The screen shown at rightappears.

Use the up or down arrow keys toselect the number, the right and leftkeys to move from number to numberin the depth. For example, to set the shallow alarm depth to 10 feet, pressthe right arrow key once, then press the up arrow key once. The changesthe second "0" to a "1". Next, press the right arrow key again and press the

19

down arrow key once. This changesthe "1" at the end of the number to a"0". The depth now shows 10 feet.

Press the ENT key to accept this set-ting. The Optima returns to the alarmsmenu, showing a shallow depth of 10feet. Now you can activate the alarmby highlighting the "Shallow Alm" labeland pressing the right arrow key.

With the shallow alarm set at ten feet,anytime the digital display goes belowten feet, the shallow alarm sounds.

Set the deep alarm in the same manner. If the bottom depth reading goesbelow the deep alarm setting, the deep alarm will sound.

ZONE ALARMThe zone alarm is triggered when anyecho passes inside the zone alarmbar, shown on the right side of thescreen. To turn the zone alarm on,highlight the "Zone Alarm" label on thealarms menu, then press the right ar-row key. To adjust the zone alarm,highlight the "Zone Adjust" label, thenpress the right arrow key. A screensimilar to the one at right appears.

To adjust the top of the zone bar higheror lower, press the up or down arrowkeys while the up and down arrows aresurrounding the "Upper Zone" on thescreen as shown above. To adjust the bottom of the zone bar, first pressthe right arrow key to move the arrows to the "Lower Zone" on the screen,then use the up or down arrow keys.

When the zone alarm is set, press the EXIT key to erase the menus.

FISH ALARMUse the fish alarm for a distinctive audible alarm when fish or othersuspended objects are detected by the Fish I.D. feature. A different tonesounds for each fish symbol size shown on the display. To turn the fish

20

alarm on, press the ALARM key, then highlight the "Fish Alarm" label andpress the right arrow key. The unit will revert to the sonar display with thefish alarm turned on. Repeat the above steps to turn the fish alarm off.

Note: If the unit is in the manual mode, turning the Fish Alarm on will alsoturn the automatic mode and Fish ID on, also.

ADJUST CHART SURFACE CLARITYThe markings extending downward from the zero line on the chart arecalled “surface clutter.” These markings are caused by wave action, boatwakes, temperature inversion, and other natural causes.

The Surface Clarity Control (SCC) re-duces or eliminates surface clutter sig-nals from the display. SCC varies thesensitivity of the receiver, decreasingit near the surface and gradually in-creasing it as the depth increases.The maximum depth that SCC willaffect is 75% of the selected depthrange. For example, on a 0-60 footrange with maximum SCC, surfaceclutter will be reduced down to 45 feet.

There are three levels of SCC avail-able on the Optima: low, medium, andhigh. When it’s turned on for the first time, the SCC level is low. To changeit, press the MENU key, then press the up or down arrow keys until the"Surface Clarity" menu appears. Now use the left or right arrow keys tochange it. When you're finished, press the EXIT key to erase the SCCmenu.

ASP (Advanced Signal Processing)The ASP feature is a noise rejection system built into the Optima thatconstantly evaluates the effects of boat speed, water conditions, andinterference. This automatic feature gives you the best display possibleunder most conditions.

The ASP feature is an effective tool in combating noise. In sonar terms,noise is any undesired signal. It is caused by electrical and mechanicalsources such as bilge pumps, engine ignition systems and wiring, airbubbles passing over the face of the transducer, even vibration from theengine. In all cases, noise can produce unwanted marks on the display.

21

The ASP feature has two levels - Nor-mal and High. If you have high noiselevels, try using the “High” ASP set-ting. However, if you are having troublewith noise, we suggest that you takesteps to find the interference sourceand fix it, rather than continually usingthe unit with the high ASP setting.However, there are times when youmay want to turn the ASP feature off.This allows you to view all incomingechoes before they are processed bythe ASP feature.

To change the ASP level, press the MENU key then press the up or downarrow keys until the "ASP" menu appears. Now use the left or right arrowkeys to change it. When you're finished, press the EXIT key to erase theASP menu.

SYSTEM SETUPThe following features are availablethrough the "System Setup" menu. Toaccess this menu, press the MENUkey, then press the up or down arrowkeys until the "System Setup" menuappears. Press the right arrow key.The screen shown at right appears.

Audio/DisplayYou can adjust the display's contrastand turn the speaker off or on usingthis menu. To do this, highlight the"Audio/Display" label on the systemsetup menu, then press the right arrowkey. The screen at right appears.

To adjust the contrast, highlight the"Contrast" menu, then use the left orright arrow key to change it. Look atthe pattern at the bottom of this screento adjust the contrast for the best sharp-ness.

To turn the speaker off, highlight the

22

"Speaker" label, then press the left arrow key to turn it off.

System InformationThis screen shows some basic data about the Optima. To view this,highlight the "System Info" label on the System Setup menu, then press theright arrow key. The system info screen appears. To erase this screen,press the EXIT key. The Optima returns to the System Setup menu.

Units of MeasureThe Optima normally shows the depthin feet, speed in statute miles per hour,distance in statute miles, and tem-perature in degrees Fahrenheit. Youcan change any of these settings us-ing the units of measure menu. To dothis, highlight the "Units of Measure"label on the System Setup menu, thenpress the right arrow key. The screenat right appears. Highlight the item youwant to change, then press the right orleft arrow key to change it. To erasethis screen, press the EXIT key.

Reset Distance LogIf you have a speed sensor attached to the Optima, the unit starts countingthe distance you've travelled each time you turn it on. You can reset thisdistance to zero by turning the unit off and on again, however, it's easierto highlight the "Reset Distance Log" label on the System Setup menu, thenpress the right arrow key. This resets the log and keeps you in the SystemSetup menu. To erase this menu, press the EXIT key.

Temperature GraphSome of the Optima's screens have a temperature graph, as shown atright. Normally, the temperature graph has a 2°range. On the screen shown at right, the tempera-ture graph has a range from 71° to 73°. You canchange this range to 4° or 10° using the "TempGraph" label on the System Setup menu. High-light that label, then press the right arrow key untilthe desired temperature graph range is high-lighted. Press the EXIT key to erase the menu.

23

SimulatorThe Optima has a simulator built in that lets you use it as if you are on thewater. All features and functions of the unit are usable. A message appearsoccasionally to remind you that the simulator is on.

To use the simulator, press the MENU key, then press the up or downarrow keys until the "System Setup" menu appears. When it does, pressthe right arrow key. Now press the up or down arrow keys until the"Simulator" label is highlighted. Finally, press the right arrow key. TheOptima returns to a sonar screen with simulated echoes scrolling acrossthe screen.

Preset OptionsThe Optima "remembers" all settingssuch as units of measure, auto/manual,sensitivity, even when power is re-moved from the unit. To return theOptima to the factory settings, high-light the "Preset Options" label on the"System Setup" menu, then press theright arrow key. The Optima returns tothe full chart screen with all settingsreturned to their factory values.

Keel OffsetThe Optima measures water depthfrom the face of the transducer. Sincethe transducer is below the surface ofthe water, this distance is not the exactwater depth. If the transducer is onefoot below the surface, and the Optimareports the water depth as 30 feet,then the depth is actually 31 feet.

You can calibrate the depth readingusing the keel offset feature. First,highlight the "Keel Offset" label on the"System Setup" menu, then press theright arrow key. The screen shown atright appears. The current bottom depth shows in the upper left corner ofthe screen. The keel offset shows in the upper right corner. In this example,we need to change the keel offset so that the Optima will add one foot to

24

the depth, since the transducer is onefoot below the surface. Press the rightarrow key, then the up or down arrowkeys until 1.0 appears in the "Adj Keel"box, as shown at right, then press theENT key. This immediately changesthe digital depth display at the top ofthe screen by one foot. Press the EXITkey to erase this menu.

Note: Another way to use the keeloffset feature is if you want to know thedepth of the water below the lowestpart of the boat, instead of the surface.To do this, measure the lowest part ofthe boat below the transducer. In thisexample, we'll use 3 feet. Now, usingthe keel offset feature, adjust the off-set for a negative 3 feet, as shown atright.

Please note that adjusting the keeloffset only affects the digital depthdisplay and all features that use thedigital depth, such as the depth alarmsand FishTrack. This doesn't affect thechart at all.

Calibrate SpeedYou can calibrate the speed display ifan optional speed sensor is attachedto the Optima. To do this, highlight the"Calibrate Speed" label on the "Sys-tem Setup" menu, then press the rightarrow key. A screen similar to the oneat right appears.

If the digital speed display is slowerthan your actual speed, add a positivepercentage to make it read faster. Ifthe digital speed display is faster, use a negative percentage to make itread slower. Use the arrow keys to change the speed, then press the ENTkey. Press the EXIT key to erase this menu.

TROUBLESHOOTINGIf your unit is not working, or if you need technical help, please use thefollowing troubleshooting section before contacting the factory customerservice department. It may save you the trouble of returning your unit.

Unit won’t turn on:1. Check the power cable’s connection at the unit. Also check the wiring.

2. Make certain the power cable is wired properly. The red wire connectsto the positive battery terminal, black to negative or ground.

3. Check the fuse.

4. Measure the battery voltage at the unit’s power connector. It should beat least 11 volts. If it isn’t, the wiring to the unit is defective, the batteryterminals or wiring on the terminals are corroded, or the battery needscharging.

Unit freezes, locks up, or operates erratically:1. Electrical noise from the boat’s motor, trolling motor, or an accessory

may be interfering with the sonar unit. Rerouting the power andtransducer cables away from other electrical wiring on the boat mayhelp. Route the sonar unit’s power cable directly to the battery insteadof through a fuse block or ignition switch

2. Inspect the transducer cable for breaks, cuts, or pinched wires.

3. Check both the transducer and power connectors. Make certain bothare securely plugged in to the unit.

Weak bottom echo, digital readings erratic, or no fish signals:1. Make certain transducer is pointing straight down. Clean the face of the

transducer. Oil, dirt, and fuel can cause a film to form on the transducer,reducing its effectiveness. If the transducer is mounted inside the hull,be sure it is shooting through only one layer of fiberglass and that it issecurely bonded to the hull. Do NOT use RTV silicone rubber adhesiveor Marinetex

2. Electrical noise from the boat’s motor can interfere with the sonar. Thiscauses the sonar to automatically increase its Discrimination or noiserejection feature. This can cause the unit to eliminate weaker signalssuch as fish or even structure from the display.

27

3. The water may be deeper than the sonar’s ability to find the bottom. Ifthe sonar can’t find the bottom signal while it’s in the automatic mode,the digital will flash continuously. It may change the range to limits fargreater than the water you are in. If this happens, place the unit in themanual mode, then change the range to a realistic one, (for example,0-100 feet) and increase the sensitivity. As you move into shallowerwater, a bottom signal should appear.

4. Check the battery voltage. If the voltage drops, the unit’s transmitterpower also drops, reducing its ability to find the bottom or targets.

Bottom echo disappears at high speeds or erratic digital reading orweak bottom echo while boat is moving1. The transducer may be in turbulent water. It must be mounted in a

smooth flow of water in order for the sonar to work at all boat speeds.Air bubbles in the water disrupt the sonar signals, interfering with itsability to find the bottom or other targets. The technical term for this isCavitation.

2. Electrical noise from the boat’s motor can interfere with the sonar. Thiscauses the sonar to automatically increase its Discrimination or noiserejection feature. This can cause the unit to eliminate weaker signalssuch as fish or even structure from the display. Try using resistor sparkplugs or routing the sonar unit’s power and transducer cables awayfrom other electrical wiring on the boat.

No fish arches when the Fish ID feature is off:1. Make certain transducer is pointing straight down. This is the most

common problem if a partial arch is displayed.

2. The sensitivity may not be high enough. In order for the unit to displaya fish arch, it has to be able to receive the fish’s echo from the time itenters the cone until it leaves. If the sensitivity is not high enough, theunit shows the fish only when it is in the center of the cone.

3. Use the Zoom feature. It is much easier to display fish arches whenzoomed in on a small range of water than a large one. For example, youwill have much better luck seeing fish arches with a 30 to 60 foot rangethan a 0 to 60 foot range. This enlarges the targets, allowing the displayto show much more detail.

4. The boat must be moving at a slow trolling speed to see fish arches.If the boat is motionless, fish stay in the cone, showing on the screenas straight horizontal lines.

28

NOISEA major cause of sonar problems is electrical noise. This usually appearson the sonar’s display as random patterns of dots or lines. In severe cases,it can completely cover the screen with black dots, or cause the unitoperate erratically, or not at all.

To eliminate or minimize the effects of electrical noise, first try to determinethe cause. With the boat at rest in the water, the first thing you should dois turn all electrical equipment on the boat off. Make certain the engine isoff, also. Turn your Optima on, then turn off ASP (Advanced SignalProcessing). There should be a steady bottom signal on the display. Nowturn on each piece of electrical equipment on the boat and view the effecton the sonar’s display. For example, turn on the bilge pump and view thesonar display for noise. If no noise is present, turn the pump off, then turnon the VHF radio and transmit. Keep doing this until all electrical equipmenthas been turned on, their effect on the sonar display noted, then turned off.

If you find noise interference from an electrical instrument, trolling motor,pump, or radio, try to isolate the problem. You can usually reroute the sonarunit’s power cable and transducer cable away from the wiring that iscausing the interference. VHF radio antenna cables radiate noise whentransmitting, so be certain to keep the sonar’s wires away from it. You mayneed to route the sonar unit’s power cable directly to the battery to isolateit from other wiring on the boat.

If no noise displays on the sonar unit from electrical equipment, then makecertain everything except the sonar unit is turned off, then start the engine.Increase the RPM with the gearshift in neutral. If noise appears on thedisplay, the problem could be one of three things; spark plugs, alternator,or tachometer wiring. Try using resistor spark plugs, alternator filters, orrouting the sonar unit’s power cable away from engine wiring. Again,routing the power cable directly to the battery helps eliminate noiseproblems. Make certain to use the in-line fuse supplied with the unit whenwiring the power cable to the battery.

When no noise appears on the sonar unit after all of the above tests, thenthe noise source is probably cavitation. Many novices or persons withlimited experience make hasty sonar installations which function perfectlyin shallow water, or when the boat is at rest. In nearly all cases, the causeof the malfunction will be the location and/or angle of the transducer. Theface of the transducer must be placed in a location that has a smooth flowof water at all boat speeds. Read your transducer owner’s manual for thebest mounting position.
