BATTERY PACKS
DRegular chargingqAttach the battery pack to the transceiver.
wBe sure to turn the transceiver power OFF.
eConnect the Wall charger or optional cable (CP-20) as
shown below.
rCharging the battery pack approx. 8 hours, depending on
the remaining power condition.
DO NOT charge BP-210N more than 12 hours. Otherwise,
BP-210N will be damaged. BP-210N must be charged for
8–12 hours only.
Optional battery caseWhen using a battery case attached to the transceiver, install
6 ×AA(R6) size Alkaline batteries as illustrated below.
qRemove the battery case from the transceiver.
wInstall 6 ×AA(R6) size Alkaline batteries.
•Be sure to observe the correct polarity.CAUTION:
•When installing batteries, make sure they are all the same
brand, type and capacity. Also, do not mix new and old
batteries together.
•Keep battery contacts clean. It’s a good idea to clean bat-
tery terminals once a week.

CLONING
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-A24 cloning software.DTransceiver to transceiver cloningqConnect the OPC-474 
CLONING CABLE
with adapter plugs
to [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 [MR•
MW
],
push [PWR] to enter cloning mode
(for operating the master transceiver
only).
•“CLONE” appears and the transceivers
enter the clone standby condition.
ePush [MR•
MW
] on the master trans-
ceiver.
•“CL-OUT” appears in the master trans-
ceiver’s display.
• “COURSE DEVIATION NEEDLES”
shows that cloning is taking place
•“CL-IN” appears automatically in the
slave transceiver’s display.
rWhen cloning is finished, turn power OFF, then ON again
to exit cloning mode.
NOTE: DO NOTtransfer the data from IC-A24 to IC-A6,
when the data contains the NAV band data. In such case,
cloning error may occur.
DCloning using PCData can be cloned to and from a PC (Microsoft
®, Windows
®
98/98SE/Me/2000/XP) using the optional CS-A24 
CLONING
SOFTWARE
and the optional OPC-478 (RS-232C type) or
OPC-478U (USB type) 
CLONING CABLE
. Consult the CS-A24
CLONING SOFTWARE
HELPfile for details.
DCloning error
NOTE: DO NOTpush [ENT•
WX
] on the slave transceiver
during cloning. This will cause a
cloning error.
When the display at right appears, a
cloning error has occurred.
In this case, both transceivers automatically return to the
clone standby condition and cloning must be repeated.
