About the battery pack
DOperating period
The operating period of the transceiver is 6 hours.
•Operating periods are calibrated for the following conditions:
at 25°C (77°F), Tx : Rx : standby = 5 : 5 : 90
DBattery pack life
If your battery pack seems to have no capacity even after
being fully charged, completely discharge it by leaving the
power ON overnight. Then, fully charge the battery pack
again.
If the battery pack still does not retain a charge (or very little),
a new battery pack must be purchased.
Battery pack CAUTION
NEVER short the terminals of the battery pack. Also, cur-
rent may flow into nearby metal objects, such as a neck-
lace, etc. Therefore, be careful when carrying with, or
placing near metal objects, carrying in handbags, etc.
Keep battery contacts clean. It’s a good idea to clean bat-
tery terminals once a week.

8CLONING
Cloning allows you to quickly and easily transfer the
programmed data from one transceiver to another transceiver,
or, data from PC to a transceiver using the optional CS-A23
cloning software.
DTransceiver to transceiver cloning
qConnect the OPC-474 CLONING CABLEwith adapter plugs
to the [SP/MIC] jack of the master and slave transceivers.
•The master transceiver is used to send data to the slave trans-
ceiver.
wWhile push and holding [Y]
+ [Z],push [PWR] ON to
enter cloning mode (for both
the master transceiver and
slave transceiver both.).
•“CLONE”appears and the
transceivers enter the clone
standby condition.
ePush [ENT] on the master
transceiver.
•“CL-OUT”appears in the
master transceiver’s display.
•“CL-IN”appears automati-
cally in the slave trans-
ceiver’s display.
rWhen cloning is finished, turn power OFF, then ON again
to exit cloning mode.NOTE: DO NOTtransfer the data from IC-A23 to IC-A5,
when the data contains the NAV band data. In such case,
cloning error may occur.
Cloning using PC
Data can be cloned to and from a PC (IBM compatible) using
the optional CS-A23 
CLONING SOFTWAREand the optional
OPC-478 
CLONING CABLE. Consult the CS-A23 CLONING
SOFTWARE
HELP message for details.
DCloning error
NOTE: DO NOTpush [ENT] on the slave transceiver dur-
ing cloning. This will cause a cloning error.
When the display at right ap-
pears, a cloning error has oc-
curred.
In this case, both transceivers automatically return to the
clone standby condition and cloning must be repeated. 
						

							9TROUBLESHOOTING
29 If your transceiver seems to be malfunctioning, please check
the following points before sending it to a service center.
POSSIBLE CAUSESOLUTIONREF.
No power comes on.•The battery is exhausted.
•Bad connection for the battery pack.•Recharge the battery pack.
•Check the connection to the
transceiver.pgs. 25,
26
No sound comes from the
speaker.•Squelch level is too deep.
•Volume level is too low.•Set squelch to the threshold point.
•Set [VOL] to a suitable level.pgs. 9, 11
Transmitting impossible.•Some channels are receive only.
•The battery is exhausted.•Change channels.
•Recharge the battery pack.p. 12
p. 25
The displayed channel
cannot be selected.•Lock function is activated.•Push [F], then push [7 (KEY LOCK)].p. 10
Scan does not start.•All memory channels are not 
programmed as “TA G” channels.•Set the “TA G” settings of desired
 channels.p. 16
No beep sounds.•Beep tones turned OFF.•Push [F], then push [8 (BEEP)] to
 adjust the beep tone level.p. 9
