VHF AIR BAND TRANSCEIVER
INSTRUCTION MANUAL
This device complies with Part 15 of the FCC rules.Operation is subject to the following two conditions: (1) This device may not cause
harmful interference, and (2) this device must accept any interference
received, including interference that may cause undesired oper ation.
i
FOREWORD
READ ALL INSTRUCTIONS carefully and completely
before using the transceiver.
SAVE THIS INSTRUCTION MANUAL— This in-
struction manual contains important operating instructions for
the IC-A23/A5.
EXPLICIT DEFINITIONS
The explicit definitions below apply to this instruction manual.
CAUTION
R WARNING! NEVER hold the transceiver so that the
antenna is very close to, or touching exposed par ts of the
body, especially the face or eyes, while transmitting. The
transceiver will perform best if the microphone is 5 to 10 cm
away from the lips and the transceiver is vertical.
R WARNING! NEVER operate the transceiver with a
headset or other audio accessories at high volume levels.
Hearing experts advise against continuous high volume operation. If you experience a ringing in your ears, reduce the
volume level or discontinue use.
NEVER connect the transceiver to an AC outlet or to a
power source of more than 14 V DC. Such a connection will
damage the transceiver.
NEVER connect the transceiver to a power source that is
DC fused at more than 5 A. Accidental re verse connection will
be protected by this fuse, higher fuse values will not give any
protection against such accidents and the transceiver will be
ruined.
NEVER short the terminals of the battery pack. Also, cur-
rent may flow into nearby metal objects, such as a necklace,
WORD DEFINITION
RWARNING
Personal injury, fire hazard or electric shock
may occur.
CAUTION
Equipment damage may occur.
NOTE
Inconvenience only. No risk of personal
injury, fire or electric shock.
FCC caution: Changes or modifications to this transceiver, not
expressly approved by Icom Inc., could void your authority to
operate this transceiver under FCC regulations.(U.S.A.only)
ii
etc.Therefore, be careful when carrying with, or placing near
metal objects, carrying in handbags, etc.
DO NOT allow children to play with any radio equipment
containing a transmitter.
DO NOT operate the transceiver near unshielded electrical
blasting caps or in an explosive atmosphere.
AVOID using or placing the transceiver in direct sunlight or
in areas with temperatures below –10°C (+14°F) or above
+60°C (+140°F).
The use of non-Icom battery packs/chargers may impair
transceiver performance and invalidate the warranty.
Even when the transceiver power is OFF, a slight current still
flows in the circuits. Remove the battery pack or case from
the transceiver when not using it for a long time. Otherwise,
the battery pack or installed dry cell batteries will become exhausted.

■ Duplex operation
(U.S.A. version only)
The duplex function allows you to call a flight service station
while receiving a VOR station. The duplex function requires
frequency programming for the flight service station in advance.
◊ Programming a duplex frequency
q Push [CLR] to select frequency mode.
w Set a NA V band frequency using the tuning dial or keypad.
•NAV band frequency range: 108.00–117.975 MHz
e Push , then [5 (DUP-W)].
•“DUP”flashes and transmit frequency appears.
r Set the frequency of the flight service station using the tun-
ing dial or keypad.When using the tuning dial, push [ENT]
after setting a frequency.
•The displayed frequency returns to the NAV band frequency.
◊ Operating the duplex function
q Set the desired frequency in NAV band.
•NAV band frequency range: 108.00–117.975 MHz
w Push , then [6 (DUP)] to turn the duplex function ON.
•“DUP” appears on the function display.
e Push and hold [PTT] to transmit at the pre-programmed
transmit frequency.
r Release [PTT] to return to receive.
t Push , then [6 (DUP)] to cancel the function.
A duplex frequency can be programmed into each memory channel independently.Set a duplex frequency before
programming the memory channel, if desired. The duplex
ON/OFF setting can also be programmed into a memory
channel.
EXAMPLE: Programming 123.65 MHz as the transmit frequency in the duplex function.

BATTERY PACKS
■ Charging
precautions
NEVER connect two or more chargers
at the same time.
Charging may not occur under temperatures of 10°C (+50°F) or over temperatures of 40°C (+104°F).
When using BC-119: If the charge
indicator flashes orange, vehicle battery voltage is low and charging is
not possible. Check the vehicle battery voltage in this case.If the charge
indicator flashes red, there may be a
problem with the battery pack (or
charger). Re-insert the batter y pack
or contact your dealer.
■ Battery pack
charging
The BP-200L BATTERY PACK includes
rechargeable Ni-MH batteries and can
be charged approx. 300 times. Charge
the battery pack before first operating
the transceiver or when the battery
pack becomes exhausted.
If you want to be able to charge the battery pack more than 300 times, the following points should be observed:
1.Av oid o vercharging.The charging period should be less than 48 hours.
2. Use the battery until it becomes almost completely exhausted under
normal conditions. We recommend
battery charging just after transmitting
becomes impossible.
D
Rapid charging with the BC-119
The optional BC-119 provides rapid
charging of battery packs.
One AD-87 and an AC adapter (may be
supplied with the BC-119 depending on
version) are additionally required.
q Fix the optional AD-88
TERMINAL PC
BOARD FOR CHARGER into the BC-

■ About the battery pack
D Operating 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
D Battery 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 necklace, 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.

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-A23
cloning software.
D Transceiver to transceiver cloning
q Connect the OPC-474 CLONING CABLEwith adapter plugs
to the [SP/MIC] jack of the master and slave tr ansceivers.
• The master transceiver is used to send data to the slave transceiver.
w While 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.
e Push [ENT] on the master
transceiver.
•“CL-OUT” appears in the
master transceiver’s display.
•“CL-IN” appears automati-
cally in the slave transceiver’s display.
r When cloning is finished, turn power OFF, then ON again
to exit cloning mode.
NOTE: DO NOT transfer 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 SOFTWARE and the optional
OPC-478
CLONING CABLE. Consult the CS-A23 CLONING
SOFTWARE HELP message for details.
D Cloning error
NOTE: DO NOT push [ENT] on the slave transceiver dur-
ing 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.
