RDANGER! NEVER short terminals of the battery pack.
Also, current may flow into nearby metal objects such as a key, so
be careful when placing the battery packs (or the transceiver) in
handbags, etc. Simply carrying with or placing near metal objects
such as a key, etc. may cause shorting. This may damage not only
the battery pack, but also the transceiver.
RDANGER! Use and charge only specified Icom battery packs
with Icom transceivers or Icom chargers. Only Icom battery packs
are tested and approved for use with Icom transceivers or charged
with Icom chargers. Using third-party or counterfeit battery packs or
chargers may cause smoke, fire, or cause the battery to burst.
RWARNING! NEVER hold the transceiver so that the an-
tenna is very close to, or touching exposed parts of the body, es-
pecially the face or eyes, while transmitting. The transceiver will
perform best if the microphone is 2 to 4 in. (5 to 10 cm) away from
the lips and the transceiver is vertical.
RWARNING! NEVER operate the transceiver with a head-
set or other audio accessories at high volume levels. The continu-
ous high volume operation may cause a ringing in your ears. If you
experience the ringing, reduce the volume level or discontinue use.
CAUTION: NEVER operate the transceiver while driving a ve-
hicle. Safe driving requires your full attention—anything less may
result in an accident.
CAUTION: MAKE SURE the flexible antenna, battery pack
and jack cover are securely attached to the transceiver, and that
the antenna and battery pack are dry before attachment. Expos-
ing the inside of the transceiver to dust or water will result in
serious damage to the transceiver.
DO NOT push [PTT] when you do not actually intend to transmit.
DO NOT modify the transceiver. The specifications may change
and then not comply with the requirements of a corresponded regu-
lation. The transceiver warranty does not cover any problems caused
by unauthorized modification.
DO NOT operate or place the transceiver in direct sunlight or
in areas with temperatures below +22°F (–30°C) or above +140°F
(+60°C).
DO NOT operate the transceiver near unshielded electrical blast-
ing caps or in an explosive atmosphere.
DO NOT use harsh solvents such as benzine or alcohol when
cleaning, as they will damage the transceiver surfaces.
BE CAREFUL! The transceiver will become hot when operating
it continuously for long periods of time.
KEEP the transceiver away from the heavy rain, and Never im-
merse it in the water. The transceiver meets IP55* requirements for
dust-protection and water jet resistance.
However, once the transceiver has been dropped, dust-protection
and water jet resistance cannot be guaranteed due to the fact that
the transceiver may be cracked, or the waterproof seal damaged, etc.
* Only when the supplied battery pack, flexible antenna and con-
nector cover are attached.

FCC INFORMATION
• FOR CLASS A UNINTENTIONAL RADIATORS:
This equipment has been tested and found to comply with the
limits for a Class A digital device, pursuant to part 15 of the
FCC Rules. These limits are designed to provide reasonable
protection against harmful interference when the equipment is
operated in a commercial environment. This equipment gener-
ates, uses, and can radiate radio frequency energy and, if not
installed and used in accordance with the instruction manual,
may cause harmful interference to radio communications.
Operation of this equipment in a residential area is likely to
cause harmful interference in which case the user will be re-
quired to correct the interference at his own expense.
CAUTION: Changes or modifications to this transceiver, not ex-
pressly approved by Icom Inc., could void your authority to oper-
ate this transceiver under FCC regulations.

BASIC OPERATION
■Channel selection
Several types of channel selections are available. Methods
may differ according to your system set up.
NON-ZONE TYPE:
To select the desired operating channel:
• Push [CH Up] or [CH Down].
• Rotate [ROTARY SELECTOR]*.
- Up to pre-programmed 16 channels can be selected.
• Push one of [MR-CH 1] to [MR-CH 4].
ZONE TYPE:
To select the desired zone:
• Push [Zone], then push [CH Up] or [CH Down].
• Push [Zone Up] or [Zone Down].
• Rotate [ROTARY SELECTOR]*.
- Up to pre-programmed 16 zones can be selected.
* Depending on the pre-setting.
When [Rotary selector] selects “Operating channel,” [CH Up]/[CH
Down] are not available.
When [Rotary selector] selects “Operating zone,” [Zone]/[Zone Up]/
[Zone Down] are not available.
AUTOMATIC SCAN TYPE:
Channel setting is not necessary for this type. When turning
power ON, the transceiver automatically starts scanning.
Scanning stops when receiving a call.
DVoting operation (for zone selection)
The transceiver automatically starts scanning when a zone,
specified for the voting operation, is selected.
The voting scan detects the S-meter of the repeater and
automatically selects the strongest station.

■Call procedure
When your system employs tone signalling (excluding
CTCSS and DTCS), this call procedure may be necessary
prior to voice transmission.The tone signalling employed may
be a selective calling system which allows you to call specific
station(s) only and prevent unwanted stations from contacting
you.
qSelect the desired TX code channel or 2/5-Tone code
according to your System Operator’s instructions.
• This may not be necessary depending on programming.
• Refer to pages 14 or 15 for selection.
wPush [Call] (assigned to one of the dealer programmable
keys).
eAfter transmitting, the remainder of your communication
can be carried out in the normal fashion.
Selective calling Non-selective calling
■Receiving and transmitting
CAUTION: Transmitting without an antenna may damage
the transceiver. See page 1 for accessory attachments.
Receiving:
qRotate [VOL] to turn the power ON.
wPush [CH Up] or [CH Down], or rotate [ROTARY SELEC-
TOR]* to select the conventional system channel, in se-
quence.
*Depending on the pre-setting.
eWhen receiving a call, adjust the audio output level to a
comfortable listening level.
NOTE: When a matched RX code signal is received, audio
from the microphone is automatically transmitted for a
specified time period.*
* Depending on the presetting. Ask your dealer for details.
Transmitting:
Wait for the channel to become clear to avoid interference.
qWhile pushing and holding [PTT], speak into the micro-
phone at a normal voice level.
• When a tone signalling system is used, the call procedure de-
scribed at the previous page may be necessary.
wRelease [PTT] to return to receive.
IMPORTANT: To maximize the audio quality of your signal;
1. Pause briefly after pushing [PTT].
2. Hold the microphone 5 to 10 cm (2 to 4 inches) from
your mouth, then speak into the microphone at a normal
voice level.

BASIC OPERATION
DTransmitting notes
• Transmit inhibit function
The transceiver has several inhibit functions which restrict
transmission under the following conditions:
- The channel is in mute condition (‘Inaudible’ condition;
“ ” (Audible indicator) does not appear.)
-The channel is busy.
-Un-matched (or matched) CTCSS is received.
(Depending on the pre-setting.)
-The selected channel is a ‘receive only’ channel.
• Time-out timer
After continuous transmission for the pre-programmed time
period, the time-out timer starts, causing the transceiver to
stop transmitting.
• Penalty timer
Once the time-out timer starts, transmission is further inhib-
ited for a period determined by the penalty timer.
DTX code channel selection
If the transceiver has [TX Code CH Select] assigned to it,
the indication can be toggled between the operating channel
number (or name) and TX code channel number (or name).
When the TX code channel number (or name) is displayed,
[CH Up] or [CH Down] selects the TX code channel.
USING [TX CODE CH SELECT] KEY:
qPush [TX Code CH Select]— a TX code channel number
(or name) appears.
wPush [CH Up] or [CH Down] to select the desired TX code
channel.
eAfter selecting, push [TX Code CH Select] to set.
• Return to the stand-by mode.
rPush [Call] to transmit the selected TX code.
USING [TX CODE CH UP]/[TX CODE CH DOWN] KEY:
If the transceiver has a [TX Code CH Up] or [TX Code CH
Down] key assignment, the programmed TX code channel
can be selected directly when pushed.
