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 electri-
cal blasting caps or in an explosive atmosphere.
DO NOT use or place 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 be-
come exhausted.
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.

is deleted, the “r1” recall channel which is stored 123.450 MHz
move up to “r0”.
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:
When the number of stored frequencies reaches
10, channels are automatically deleted as needed, in the
order they were entered, beginning the oldest.

The lock function prevents accidental frequency changes
and accidental function activation.
qPush , then push [7• ] to turn the lock function ON.
• “ ” appears.
wTo turn the function OFF, repeat step qabove.
• “ ” disappears.
■Setting beep tone
If desired, the beep tone, which sounds at the push of a
switch, can be set.
q Push ,then push [8•BEEP] to enter the beep tone
setting mode.
w Rotate [DIAL] to set the beep level.
• ‘BEP-- 0’ is OFF and ‘BEP-- 9’ is maximum level.

e Push [CLR•DEL] to exit the beep tone setting mode.
■Side tone function
When using an headset (other manufacture’s product),
the transceiver outputs your transmitted voice to the head-
set for monitoring. Connect the optional headset with the
transceiver when using this function (OPC-499 HEADSET
ADAPTER and headset are required). (p. 33)
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.

ever, the transceiver can be programmed by your dealer
to show the operating frequency first. Push [MR•MW] to
display the comment in this case.
■Transferring memory
contents
This function transfers a memory channel’s contents into the
frequency mode. This is useful when searching for signals
around a memory channel’s frequency.
qPush [MR•MW] to select memory mode.
wSelect the desired memory channel to be transferred
using [DIAL] or keypad.

■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].
r To stop the scan, push [CLR•DEL].
■Memory scan
q Push [MR•MW] to select the memory mode.
• Push , then push [0•BANK] to select the BANK number, if
desired. Push [CLR•DEL] to exit the BANK selection mode.
wPush [SQL], then rotate [DIAL] to set the squelch level to

• To change the scanning direction, rotate [DIAL].
r To stop the scan, push [CLR•DEL].
NOTE: Program 2 or more memory channels to start the
memory scan.
MEMORY SCAN
Repeatedly scans all se-
lected memory BANK’s
“TAG” memory channels.
Used for checking often-
used channels and bypass-
ing usually busy channels
such as control-tower fre-
quencies.
COM BAND SCAN
Repeatedly scans
all frequencies
over the entire
COM band.
