RDANGER! NEVER short the terminals of the bat-
tery pack.
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 2 to 4 in. (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.
CAUTION: NEVER use non-Icom battery packs/
chargers to prevent the loss of the transceiver’s good per-
formance and warranty.
DO NOT push PTT when not actually desiring to transmit.
DO NOT use or place the transceiver in direct sunlight or
in areas with temperatures below +22°F (–30°C) or above
+140°F (+60°C).
The basic operations, transmission and reception of the
transceiver are guaranteed within the specified operating
temperature range. However, the LCD display may not be
operate correctly, or show an indication in the case of long
hours of operation, or after being placed in extremely cold
areas.
DO NOT modify the transceiver for any reason.
KEEP the transceiver away from the heavy rain, and
Never immerse it in the water. The transceiver construction
is water resistant, not waterproof.

BASIC OPERATION
■Turning power ON
Prior to using the transceiver for the first time, the battery
pack must be fully charged for optimum life and operation.
(p. 35)
qRotate [VOL] to turn the power ON.
wIf the transceiver is programmed for a start up password,
input the digit codes as directed by your dealer.
• 10-keypad can be used for password input.
• The keys in the table below can be used for password input:
• The transceiver detects numbers in the same block as identical.
Therefore “01234” and “56789” are the same.
e When the “PASSWORD” indication does not clear after
inputting 4 digits, the input code number may be incorrect.
Turn the power off and start over in this case.
DBattery type selection
The battery type must be selected according to the attaching
battery type when tuning the transceiver ON.
➥ While pushing and holding [EMERGENCY] and [PTT], ro-
tate [VOL] to toggle the attaching battery type.
• After the display appears, release [EMERGENCY] and [PTT].
• “ DRY BATT” is displayed for about 3 sec. then “Lo” (low power
indicator) appears when the battery case operation is selected.
• “LI-ION” is displayed for about 3 sec. when the Lithium-ion bat-
tery operation is selected.

3BASIC OPERATION
■Channel selection
Several types of channel selections are available. Methods
may differ according to your system set up.
NON-BANK 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].
BANK TYPE:
To select the desired bank:
• Push [Bank], then push [CH Up] or [CH Down].
• Rotate [ROTARY SELECTOR]*.
- Up to pre-programmed 16 banks can be selected.
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.
* Depending on the pre-setting.
When the [Rotary selector] activates as the “Operating channel”
selection, [CH Up]/[CH Down] are not available for the channel se-
lection.
When the [Rotary selector] activates as the “Operating bank” se-
lection, [Bank] is not available for the bank selection.
■Call procedure
When your system employs tone signaling (excluding CTCSS
and DTCS), the 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 ac-
cording to your System Operator’s instructions.
• This may not be necessary depending on programming.
• Refer to page 14 or 15 for selection.
w Push [Call] (assigned to one of the dealer programma-
ble keys: [UP], [DOWN], [P0], [P1], [P2], [P3], [RED] and
[Monitor]) or [PTT].
eAfter transmitting a 2/5-tone code, the remainder of your
communication can be carried out in the normal fashion.
Selective calling Non-selective calling

BASIC OPERATION
■Receiving and transmitting
NOTE: Transmitting without an antenna may damage the
transceiver. See p. 1 for antenna attachment.
Receiving:
q Rotate [VOL] to turn the power ON.
w Push [CH UP] or [CH DOWN], or rotate [ROTARY SE-
LECTOR]* to select a channel, in sequence.
*Depending on the pre-setting.
e When receiving a call, adjust the audio output level to a
comfortable listening level.
Transmitting:
Wait for the channel to become clear to avoid interference.
q While pushing and holding [PTT], speak into the micro-
phone at a normal voice level.
w Release [PTT] to return to receive.
IMPORTANT: To maximize the audio quality of your signal;
1. Pause briey 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 nor-
mal voice level.
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;
“” 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 is activated, causing the trans-
ceiver to stop transmitting.
• Penalty timer
Once the time-out timer is activated, transmission is further
inhibited for a period determined by the penalty timer.
