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.

Data cloningCloning allows you to quickly and easily transfer the pro-grammed contents from one transceiver to another; or , datafrom a PC to a transceiver using the optional CS-2100CLONING SOFTWARE.
➀ Connect the OPC-474 cloning cable with adapter plugs tothe [SP] jack of the master and slave transceivers.• The master transceiver is used to send data to the slave trans-
ceiver.
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.

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.

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.
