VHF AIR BAND TRANSCEIVER
INSTRUCTION MANUAL
This device complies with Part 15 of the FCC rules.Operation is sub-
ject 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 operation.

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
RWARNING! NEVER hold the transceiver so that the
antenna is very close to, or touching exposed parts 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.
RWARNING! NEVER operate the transceiver with a
headset or other audio accessories at high volume levels.
Hearing experts advise against continuous high volume op-
eration. 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 reverse 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 ex-
hausted.
