WORD DEFINITION

RWARNINGPersonal injury, fire hazard or electricshock may occur.

CAUTION Equipment damage may occur.

NOTEIf disregarded, inconvenience only. No riskof personal injury, fire or electric shock.

CAUTIONS

During mobile operation, DO NOT operate the transceiverwithout running the vehicle’s engine. When transceiver poweris ON and your vehicle’s engine is OFF, the vehicle’s batterywill soon become exhausted.

BE CAREFUL! The transceiver will become hot whenoperating it continuously for long periods.

AVOID using or placing the transceiver in direct sunlight orin areas with temperatures below –10°C (+14°F) or above+60°C (+140°F).

AVOID the use of chemical agents such as benzine or al-cohol when cleaning, as they can damage the transceiver’ssurfaces.

USE Icom microphones only (supplied or optional). Othermanufacturer’s microphones have different pin assignmentsand may damage the transceiver if attached.

For U.S.A. onlyCaution: Changes or modifications to this transceiver, not ex-pressly approved by Icom Inc., could void your authority tooperate this transceiver under FCC regulations.

8 SCRATCH PAD MEMORY

What is scratch pad memory?During VFO operation, the transceiver automatically memo-rizes operating frequency information when transmitting on anew frequency. There are 2 types of scratch pad memories,those for simplex operation, L1–L3, and those for duplex (re-peater) operation, r1–r3. These memories can be conve-niently recalled.

NOTE: When memory mode is selected, the frequency isnot programmed into a scratch pad.

Calling up a scratch padmemory

➁ Rotate the tuning dial to select a scratch pad memory.• Previously transmitted frequency and one of “L1”–“L3” or

“r1”–“r3” appears.

• When first applying power of after CPU resetting, scratch pad

memories contain no data and therefore cannot be selected.

➂ Push [V/MHz] or [M/CALL] to exit the scratch pad memory.

NOTES: The 3rd scratch pad memory (L3 or r3) will be cleared

when transmitting on a new frequency. If the transmit fre-quency is already stored in a scratch pad memory, thescratch pad memory is not cleared but the order ischanged.

When transmitting on a scratch pad memory, the scratchpad memory becomes the 1st scratch pad memory (L1or r1) and the order is changed.

➁ While pushing [M/CALL] (second switch from right)x, turnpower ON to enter cloning mode (master transceiveronly—power on only for slave transceiver).• “CLONE” appears and the

transceivers enter the clone

standby condition.

➂ Push [S.MW] on the master transceiver.• “CLOUT” appears in the mas-

ter transceiver’s display and

the S/RF indicator shows that

data is being transferred to the slave transceiver.

• “CL IN” appears automatically

in the slave transceiver’s dis-

play and the S/RF indicator

shows that data is being received from the master transceiver.

➃ When cloning is finished, turn power OFF, then ON to exitcloning mode.

AT POWER ON D Cloning using a PCData can be cloned to and from a PC (IBM compatible) usingthe optional CS-2100 CLONING SOFTWARE and the optionalOPC-478 CLONING CABLE. Consult the CS-2100 CLONING

SOFTWARE HELP file for details.

D Cloning error NOTE: DO NOT push any key on the slave transceiver

during cloning. This will cause a cloning error.

When the display at right ap-pears, a cloning error has oc-curred.

In such a case, both transceivers automatically return to theclone standby condition and cloning must be repeated.

15 MAINTENANCE

Troubleshooting If your transceiver seems to be malfunctioning, please checkthe following points before sending it to a service center.

PROBLEMNo power comes on.

No sound comes from thespeaker.

Sensitivity is low and onlystrong signals are audible.

No contact possible withanother station.

Repeater cannot be ac-cessed.

Frequency cannot be set.

Frequency cannot be setvia the microphone.

POSSIBLE CAUSE• Power connector has a poor contact.• Polarity of the power connection is reversed.

• Blown fuse.

• Volume is too low.• The audio mute function is activated.• Squelch is set too tight.• A selective call or squelch function is activated

such as pocket beep or tone squelch.

• Antenna feedline or the antenna connector sol-der has a poor contact or is short circuited.

• The transceiver is set to semi-duplex.• The other station is using tone squelch.

• Wrong offset frequency is programmed.• Wrong subaudible tone frequency is pro-

grammed.

• The frequency lock function is activated.• Priority watch is paused on the watching fre-

quency.

• The frequency lock function is activated.

• The microphone keypad lock function is acti-vated.

• Priority watch is paused on the watching fre-quency.

SOLUTION• Check the connector pins.• Reconnect the power cable observing the proper

polarity. Replace the fuse if damaged.• Check the cause, then replace the fuse.

• Rotate [VOL] clockwise.• Push any switch or key to deactivate it.• Set the squelch level to the threshold.• Turn the appropriate function OFF.

• Check, and if necessary, replace the feedline orsolder the antenna connector again.

• Set to simplex.• Turn the tone squelch function ON.

• Correct the offset frequency.• Correct the subaudible tone frequency.

• Turn the function OFF.• Push [(M/CALL)PRIO] to resume the watch.

• Push and hold [LOCK] to deactivate the frequencylock function.

• Push [FUNC] then [#16KEYLOCK] to deactivatethe microphone keypad lock function.

• Push [(M/CALL)PRIO] to resume the watch.

PROBLEMSome memory channelscannot be selected via themicrophone keypad.

Scan does not operate.

Transmission is automati-cally cut off.

Transmission continueseven when the PTT is re-leased.

The function displayshows erroneous informa-

POSSIBLE CAUSE• The input channel number has not yet been pro-

grammed.

• The squelch is open.• The selected scan edge memory channels (e.g.

1A and 1b) have the same frequencies (for pro-grammed scan).

• Only 1 memory channel is programmed or otherchannels are set as skip channels.

• Priority watch is activated.

• Time-out timer is activated.

• One-touch PTT function is activated.

• The CPU is malfunctioning.

SOLUTION• Rotate the tuning dial to check whether the chan-

nel has been programmed or not.

• Set the squelch to the threshold point.• Reset the scan edges.

• Program other memory channels or cancel thememory skip function in the desired channels.

• Turn the function OFF.

• Set the timer to OFF.

• Turn the function OFF.

• Reset the CPU.

15 MAINTENANCE

Fuse replacementIf the fuse blows or the transceiver stops functioning, find thesource of the problem if possible, and replace the damagedfuse with a new, rated one (FGB 20 A) as shown below.

Partial CPU resettingIf you want to initialize the operating conditions without clear-ing the memory contents, etc., a partial reset function is avail-able for the transceiver.

While pushing [V/MHz] (far right switch) + [PWR], turn powerON. Initialized settings: VFO frequency, SET mode settings. Retained settings: Memory channels, call channel, scratch

pad memories, DTMF memories, mem-ory names, initial SET mode settings.

AT POWER ON

Resetting the CPUThe function display may occasionally display erroneous in-formation (e.g. when first applying power). This may becaused externally by static electricity or by other factors.

If this problem occurs, turn power OFF. After waiting a fewseconds, turn power ON again. If the problem persists, per-form the following procedure.• Partial resetting is also available. See previous section for details.

vCAUTION: Resetting the transceiver CLEARS all memoryinformation and initializes all values in the transceiver.

While pushing [SET] (far left switch) + [S.MW], turn powerON.• “CLEAR” appears and the transceiver is reset.
