PRECAUTION
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 11.5 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,
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 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 –20°C or above +55°C.
CLEAN and wipe dry the battery terminals after using the
transceiver in wet conditions. The terminals may rust if not
dried.
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 Alkaline cell batteries will become
exhausted.

porated (Japan) in the United States, the United Kingdom, Germany, France,

IMPORTANT!: IC-A24E/A6E is for GROUND STATION
USE ONLY. The IC-A24E/A6E CAN NOT and
SHOULD NOT be used in an aircraft or as the MAIN
RADIO.

3BASIC OPERATION
■Low battery indicator
Low battery indicator appears
when the battery power has de-
creased to a specified level. The
attached battery pack requires
recharging.
■Recall function
The recall function stores the last 10 frequencies used.
The function stores frequencies when the frequency is pro-
grammed and transmitted on (except memory and emer-
gency channels).

➥Push to call the 1st stored frequency.
➥Push to call the 10th stored frequency.
➥Push [CLR•DEL] to exit the recall function.
DDeletes the stored recall channel
qPush or to select the deleting recall channel.
wPush , then push [CLR•DEL] for 2 sec. to delete it.
•(e.g.) Deletes “r0”recall channel which is stored 120.450 MHz,
and “r1”recall channel stores 123.450 MHz.
DReplaces the stored recall channel
qPush or to select the recall channel to be re-
placed.
wPush , then push or to replace it.
•Replaces the selected channel into the previous channel when
is pushed and then is pushed.
•Replaces the selected channel into the next channel when
is pushed and then is pushed.
•(e.g.) To replace “r0”which is stored as 121.375 MHz into “r1”,
push , then push .
NOTE: Deletes in order of old recall channel automatically
when stored frequencies exceeds 10 channels.

•“ ”disappears.
■Side tone function
When using an headset (other manufacture’s product), the
transceiver outputs your transmitted voice to the headset for
monitoring. Connect the optional headset with the transceiver
when using this function (OPC-499 HEADSET ADAPTER and
headset are required).
(p. 32)
DSetting the side tone level
qPush [PTT] to turn the transmit mode ON.
wDuring transmit mode, rotate [DIAL] to adjust the monitor-
ing level.
•‘ST--0’is OFF and ‘ST--10’is Max. level.
NEVER operate the transceiver with a headset at high vol-
ume levels for long period. A ringing in your ears may
occur. If so, reduce the monitor level or discontinue use.
■Setting beep tone
The beep tone which sounds at the push of a switch can be
set, if desired.
qPush , then push [8•BEEP] to enter the beep tone
setting mode.
wRotate [DIAL] to set the beep level.

5SCAN OPERATION
■Scan types
The transceiver has 2 scan types to suit your needs.
■COM band scan
qPush [CLR•DEL] to select the frequency mode.
wPush [SQL], then rotate [DIAL] to set the squelch level to
the point where noise is just muted.
ePush , then push [ANL•SCAN] to start the scan.
•When a signal is received, the scan pauses until it disappears.
•To change the scanning direction, rotate [DIAL].
rTo stop the scan, push [CLR•DEL].
■Memory scan
qPush [MR•MW] to select memory mode.
•Push , then push [0•BANK] to select the BANK number if de-
sired. Push [CLR•DEL] to exit the BANK selection mode.
wPush [SQL], then rotate [DIAL] to set the squelch level to
the point where noise is just muted.
ePush , then push [ANL•SCAN] to start the scan.
•When a signal is received, the scan pauses until it disappears.
•To change the scanning direction, rotate [DIAL].
rTo stop the scan, push [CLR•DEL].
NOTE: Program 2 or more memory channels to start
memory scan.
MEMORY SCAN
Repeatedly scans se-
lected memory BANK’s
all “TAG”memory chan-
nels. Used for checking
often-used channels and
bypassing usually busy
channels such as con-
trol-tower frequencies.
COM BAND SCAN
Repeatedly scans
all frequencies
over the entire
COM band.
