NOTE: It is imperative that you fully charge both thetransmitter and the receiver battery packs prior toeach flying session. To do so, using the included wallcharger, leave the charger and batteries connected

overnight (16 hours). The first charge should beapproximately 0 hours in order to fully chargeboth battery packs to peak capacity.

The charger supplied with this system is designedto recharge your batteries at a rate of 110mA for thetransmitter and 110mA for the receiver battery pack.

Transmitter Polarity

The center pin on all JR transmitters is negative.Therefore, the center pin on all JR chargers is negative, notpositive. This is different from many other manufacturerschargers and radio systems. Beware of improperconnections based on color coded wire leads, as theymay not apply in this instance. You must make sure thatthe center pin of your JR transmitter is always connectedto the negative voltage for correct polarity hookup.

Charger

The pilot lamps should always be ON during the chargingoperation. If theyre not, check to make sure that both thetransmitter and receiver are switched OFF. Do not usethis charger for equipment other than JR. The chargingplug polarity may not be the same and equipment damagecan result. During the charging operation, the chargerstemperature is slightly elevated. This is normal.

1. Leave the transmitter power switch in the OFF position.The transmitter will not transmit radio frequency (RF) inthis position.

. Plug the DSC cord (optional JRPA1) into the DSCport in the rear of the transmitter.

. The encoder section of the transmitter will now be

operational and the LCD display will be lit.

. Plug the other end of the DSC cord into the receivercharge receptacle. Turn the switch harness to the ONposition.

NOTE: The DSC function will only operate with theJRPA001 Deluxe Switch Harness, or the JRPA00Charge Switch. When you install the charging jack,be sure to hook the charging jack receptacle securelyinto the switch harness charge cord.

Why you should use the DSC function:

1. The DSC function allows you to make adjustmentsto your model without transmitting any radio signals.Therefore, if another pilot is flying on the samefrequency, you can adjust your models radio settingand not interfere with the other pilots aircraft.

Using the Synthesied Channel Selection

The XP70 allows the selection of channels 1 through60 via the onscreen programming. When the transmitteris first turned on, the screen will display WARNING! andthe current channel and frequency used will be displayed.At this time no signal is being transmitted. If you wishto transmit on this frequency, press the clear key and thetransmitter will begin transmitting on the selected channeldisplayed and the screen will display the main menu.

Enter the system set up mode by pressingand holding the Downand Selectkeys

simultaneously while turning on the power switch.

Press the UPor Downkey until SYNTHESIzEDCH appears on screen as shown.

Press the IncreaSeor DecreaSekey to selectthe desired channel.

Press the Downand Selectkey to exit thesynthesized screen. This will return the screen tothe warning menu.

In the warning menu, the newly selected channel

will be displayed. If you wish to transmit on thatchannel, press the clearkey and the transmitterwill transmit and the screen will switch to the mainmenu screen.

The XP70 can transmit in either Pulse Code Modulation(S-PCM and Z-PCM) or in Pulse Position Modulation

(PPM, commonly referred to as FM). Be certain to observethe following guideline: Do not operate your transmitterwhen another transmitter is using the same frequency,regardless of whether the second transmitter is PCM, PPM(FM) or AM. You can never operate two transmitterson the same frequency simultaneously withoutcausing interference to both receivers. See Page0 (aircraft) or Page 77 (helicopter) for more details aboutselecting the modulation type.

Advanced Digital Trims

The XP70 employs digital trim levers on aileron,elevator, throttle, and rudder. (Hover pitch and hoverthrottle for helicopters). The ADT (Advanced Digital Trim)feature is designed to automatically store the selected trimvalues for each model. When a different model is selected,

the previously stored trim positions for that model areautomatically recalled. When using the helicopter programeach flight mode has its own trim that is automaticallyrecalled each time that flight mode is entered.

Visual trim positions are displayed on the main screen.The trims also feature dual speed scrolling. Holding thetrim lever for an extended time will cause the trim rate ofchange to increase.



It is extremely important that your radio system becorrectly installed in your model. Here are a fewsuggestions for installing your JR equipment:

1. Wrap the receiver in protective foam rubber that isno less than /8-inch thick. Secure the foam to thereceiver with #6 rubber bands. This protects the

receiver from shock in the event of a crash or a veryhard landing.

. The servos should be mounted using rubber grommetsand brass bushings to isolate them from vibration. Donot over-tighten the mounting screws; this will negatethe vibration absorption effect of the rubber grommets.The diagram below will assist you in properly mountingyour servo. The brass bushings are pushed from thebottom up in the rubber grommets. When the servoscrew is tightened securely, it provides the proper

security, as well as the proper vibration isolation, foryour servo.

. The servos must be able to move freely over their entirerange of travel. Make sure that the control linkages donot bind or impede the movement of any of the servos.

. Mount all switches away from the engine exhaust andaway from any high vibration areas. Make sure eachswitch operates freely and is able to operate over its

full travel.. Mount the receiver antenna firmly to the airplane

to ensure that it will not become entangled in thepropeller or control surfaces.

The XP70 offers a programmable Trainer function thatallows the transmitter to operate in three different Trainermodes.

Normal:The transmitter can be used as a master or slave but theslave transmitter must have the same programming (i.e.

reverse, travel adjust, dual rates, mixes sub trims, etc.) asthe master.

P-Link:Pilot Link is where the master transmitter maintains controlof all primary and secondary functions (i.e. Dual Rate,Expo, Gear, Flaps, etc.) and only the primary stick controls(aileron, elevator, rudder and throttle) are transferred to theslave transmitter.

NOTE: If the slave transmitter is a normal transmitteror if another JR radio is used in normal TRAINERmode (not in a P-LINK/Slave mode), all programmingfunctions must match the master transmitter.

Slave/P-link:

In the Slave mode, the XP70 is used as a slave radio inconjunction with a JR radio that is used as the master thatis in P-LINK mode; there is no need to match the slavesprogramming to the master transmitters programming.

The Dual Rate function allows two control rates (controlthrows) to be programmed and selected with a switch.Dual rates are available on the aileron, elevator andrudder channels. Changing the dual rate value not only

affects the maximum control authority but also affectsthe overall sensitivity of control. A higher rate yields ahigher overall sensitivity. The sensitivity around centercan be tailored using the Exponential function to preciselyadjust control feel.

Dual rates can be controlled by their respective dual rateswitches (aileron, elevator and rudder) or by 1 common sw(COM AILE, COM ELEV, COM RUDD, FLAP0 or FLAP).The choices for this are found on the D/R SWITCH SEL

screen in the System Set-up Mode for Airplanes.

Dual rates are available for the aileron, elevator andrudder channels. Dual rate values are adjustable from0-1%. The factory default settings for both the 0 and 1switch positions are 100%. Either switch position may beselected as the low or high rate by placing the switch inthe desired position and adjusting the value accordingly.

The Exponential function allows two exponential rates tobe programmed and selected with a switch. Exponentialis available on the aileron, elevator and rudder channels.Changing the exponential value does not affect themaximum control authority but only affects controlsensitivity. Exponential is normally used to reduce controlsensitivity around neutral while still allowing high controlauthority at the extremes of throw. The sensitivity aroundcenter can be tailored using the Exponential function toprecisely adjust control feel.

Exponential rates can be controlled by their respectiverate switches (aileron, elevator and rudder), or combinedon a single switch (COM AILE, COM ELEV, COM RUDD,FLAP0 or FLAP). The choices for this are found on theD/R SWITCH SEL screen in the System Setup Mode forAirplanes.

Exponential is available for the aileron, elevator and rudderchannels. Expo values are adjustable from 100% - LIN- +100%. The factory default settings for both the 0 and 1switch positions are LIN or 0%. Either switch position maybe selected to give any desirable EXPO rate by placingthe switch in the desired position and adjusting the valueaccordingly.

When the Automatic Landing Function is active, thethrottle stick will activate the landing system you havejust set up. Any point of throttle stick travel can be setas the auto-land point. Once the throttle stick passesthrough this point and the LAND switch is in the ON, ordown position, the landing system will be activated. Thus,the elevator, flaps and spoilers would be activated, if allwere selected. If the flap mixing switch is not in the LANDposition, the throttle stick operation would have no effecton the landing system.

Automatic Landing

To Activate the Automatic Landing feature:

1. Press the Selectkey until AUTO is highlighted

. Press either the IncreaSeor DecreaSekey toactivate the Automatic Landing System. To change

this value, press the IncreaSeor DecreaSekeyto adjust the value (0% = low stick while 100% = fullstick). To clear the auto land point, press clearandthe display will return to INH.

The XP70 offers six (6) programmable mixes that allowstick or switch inputs to control the output of two or moreservos. This function allows mixing any one channel toany other channel or the ability to mix a channel to itself.The mix can remain ON at all times, or it can be switchedOFF in flight, using a number of different switches. Mixvalues are adjustable from 0 to 1%. Each channel isidentified by a four-character name (i.e., Aileron - AILE,Elevator - ELEV, etc.). The channel appearing first is themaster channel. The second channel is the slave channel.For example, AILE - RUDD would indicate aileron torudder mixing. Each time the aileron stick is moved, theaileron will deflect, and the rudder will automaticallymove in the direction and to the position based on thevalue input in the programmable mix screen. Mixingis proportional, so small inputs of the master channelwill produce small outputs of the slave channel. Each

programmable mix has a mixing offset. The purpose of themixing offset is to redefine the neutral position of the slavechannel.

NOTE: programmable mix and 6 have a builtin trim include function. If programmable mix or 6is selected and a master channel is selected thathas a trim lever (ie. aileron, elevator rudder orthrottle) the trim will operate both the master andthe slave channel.

The Fail-Safe/Hold Function is available only when youuse PCM modulations (see Modulation Page 0). Duringloss of signal, this function drives the servos to either thefail-safe preset positions or holds the last signal position.As noted, if you are in the PPM modulation, the Fail-Safe/Hold function is not applicable. Therefore, the Fail-Safe/Hold function will not appear on your LCD in PPMmode. Refer to the Modulation Selection Section for moreinformation.

In Function Mode, use the UPor Downkeys to selectthe FAIL SAFE screen.

Press the Selectkey to highlight the desired channel.

Press the IncreaSeor DecreaSekeys to selectfail-safe (F.S.) (the servo goes to a preset programmedposition during signal loss) or HOLD (the servo holds lastposition during signal loss).

Adjust each channel by selecting the channel desired with

the Selectkey. With the stick/switch in the desired fail-safe position, press the clearkey to store these fail-safepositions in memory.

NOTE: To test the fail-safe, turn the transmitter off.Any channel set to a fail-safe position should driveto that position, and any servo set to hold shouldremain in its last good position.

NOTE: The factory default settings for the Fail-Safe

function have the Throttle channel set to Fail-Safe-170 (Low Throttle) and all other channels are set tohold the last good signal.
