FCC INFORMATION
• FOR CLASS B UNINTENTIONAL RADIATORS:
This equipment has been tested and found to comply with
the limits for a Class B digital device, pursuant to part 15 of
the FCC Rules. These limits are designed to provide reason-
able protection against harmful interference in a residential
installation. This equipment generates, uses and can radiate
radio frequency energy and, if not installed and used in ac-
cordance with the instructions, may cause harmful interfer-
ence to radio communications. However, there is no guaran-
tee that interference will not occur in a particular installation.
If this equipment does cause harmful interference to radio or
television reception, which can be determined by turning the
equipment off and on, the user is encouraged to try to cor-
rect the interference by one or more of the following meas-
ures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and re-
ceiver.
• Connect the equipment into an outlet on a circuit differ-
ent from that to which the receiver is connected.
• Consult the dealer or an experienced radio/TV techni-
cian for help.

RCAUTION! 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
(2 to 4 in.) away from the lips and the transceiver is vertical.
RCAUTION! NEVER operate the transceiver with a
headset or other audio accessories at high volume levels.
RCAUTION! NEVER short the terminals of the bat-
tery pack.
RCAUTION! 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 –30°C (+22°F) or above
+60°C (+140°F).
The basic operations, transmission and reception of the
transceiver are guaranteed within the specified operating
temperature range. However, the LCD display may not oper-
ate 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. The transceiver warranty
does not cover any problems caused by unauthorized modi-
fication.
BE CAREFUL! The transceiver meets IP57 require-
ments for dust-protection and waterproof protection. How-
ever, once the transceiver has been dropped, dust-protection
and waterproof protection cannot be guaranteed due to the
fact that the transceiver may be cracked, or the waterproof
seal damaged, etc.
For U.S.A. only
CAUTION! Changes or modifications to this transceiver, not
expressly approved by Icom Inc., could void your authority to
operate this transceiver under FCC regulations.

•
DO NOT connect the antenna other
than listed on p. 23.
• Transmitting without an antenna may
damage the transceiver.
DBattery pack
To attach the battery pack:
Slide the battery pack on the back of the transceiver in the direc-
tion of the arrow (q), then lock it with the battery release button.
• Slide the battery pack until the battery release button makes a ‘click’
sound.
To release the battery pack:
Slide the battery release button in the direction of the arrow
(w) as shown below. The battery pack is then released.

■Turning power ON
• Prior to using the transceiver for the first time, the battery
pack must be fully charged for optimum life and opera-
tion. (p. 17)
• When you use the transceiver for the first time, or after
the transceiver has sat unused for a long time, make
sure to check the date and time indication after turning
the power ON. If the time and date are not correct, reset
them. (p. 15)
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 depending on ver-
sion.
• 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.

• 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].
• Rotate [ROTARY SELECTOR]*.
- Up to pre-programmed 16 zones can be selected.
AUTOMATIC SCAN TYPE:
Channel setting is not necessary for this type. When turn-
ing power ON, the transceiver automatically starts scanning.
Scanning stops when receiving a call.
* 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.

■Receiving and transmitting
NOTE: Transmitting without an antenna may damage the
transceiver. See p. 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 a channel, in sequence.
*Depending on the pre-setting.
eWhen receiving a call, adjust the audio output level to a
comfortable listening level.
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.
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 in.) from your
mouth, then speak into the microphone at a normal
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.)
- Un-matched (or matched) NAC is received*.
(Depending on the pre-setting.)
*Digital mode operation only.
- 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.

■User set mode
The user set mode is accessed at power ON and allows you
to set seldom-changed settings.You can “customize” the trans-
ceiver operation to suit your preferences and operating style.
When you operate Non display type, this function is not
available.
Entering the user set mode:
qWhile pushing and holding [I] and
[II], rotate [VOL] to turn the power
ON.
• Turn power OFF in advance.
• “SET MODE” appears for 1 sec at
power ON.
wPush and hold [Ω] to enter user
set mode.
ePush [Ω] several times to select
the appropriate item.
Then push [∫] or [√] to set the
desired level/condition.
• Available set mode functions are
Backlight, LCD contrast, Beep,
Beep Level, Ringer Level, SQL
Level, AF Min Level, Mic Gain,
VOX Gain*, VOX Delay*, Horn,
Battery Voltage, Signal Moni and
System info.
* Appears only when the external
VOX unit is connected. The VOX
unit is available in the near future.
rPush and hold [Ω] again to exit
the user set mode.
• Until turning power OFF, [Ω], [∫] and [√] is not activated as the
assigned key function.
NOTE: While in the user set mode, [Ω], [∫] and [√] are
activated as described above regardless of the assigned
key function.
User set mode is also available using a programmable key.
Refer to p. 9 [User Set Mode] section for instructions regard-
