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/ char-
gers to prevent the loss of the transceiver’s good performance
and warranty.
DO NOT push [PTT] when not actually desiring to trans-
mit.
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).
DO NOT modify the transceiver for any reason.
READ ALL INSTRUCTIONS carefully and com-
pletely before using the transceiver.

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 reasonable
protection against harmful interference in a residential instal-
lation. This equipment generates, uses and can radiate radio
frequency energy and, if not installed and used in accordance
with the instructions, may cause harmful interference to radio
communications. However, there is no guarantee that inter-
ference will not occur in a particular installation. If this equip-
ment 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 correct the inter-
ference by one or more of the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and re-
ceiver.

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 transceiver
to stop transmitting.
• Penalty timer
Once the time-out timer is activated, transmission is further
inhibited for a period determined by the penalty timer.
• PTTID call
The transceiver sends the ID code (DTMF or digital ANI) au-
tomatically when [PTT] is pushed (beginning of transmission)
and released (end of transmission) depends on the setting.

NOTE: User set mode is also available via a programmable
function key. Refer to “USER SET MODE KEY.” (p. 9)
■Priority A channel selection
Depending on the presetting, the Priority A channel is selected
each time the transceiver power is turned ON.
■Emergency Call
When [Emergency] is pushed for the specified time period*,
the emergency signal is transmitted once, or repeatedly, on
the specified emergency channel.
A repeat emergency signal is automatically transmitted until
the transceiver receives an acknowledgement signal, or you
turn the transceiver power OFF.
When no emergency channel is specified, the signal is trans-
mitted on the previously selected channel.
If you want to cancel the emergency call, push and hold
[Emergency] again before transmitting the call.
If your transceiver is programmed for Silent operation, you
can transmit an Emergency call without the beep sounding
and the LED indicator lighting.
IMPORTANT: It is recommended to set an emergency
channel individually to provide the certain emergency call
operation.
* Depending on the presetting. Ask your dealer for details.

DNOTES
Depending on the presetting, the following functions are auto-
matically activated. Ask your dealer for details.
• Auto TX function
After the emergency call transmission, audio from the micro-
phone is automatically transmitted for a specified time period.*
• Auto RX function
After the emergency call transmission, the transceiver stands
by in the audible mode for the specified time period.*
■Man Down Emergency Call
This function requires the optional UT-124R man down unit.
When the transceiver has been left in a horizontal position for
the specified time period*, the transceiver enters the emer-
gency mode, and then the countdown starts.
After the specified time period* has passed, an emergency
call is automatically transmitted once, or repeatedly.
If the transceiver is placed in a vertical position before the first
transmission, the transceiver exits the emergency mode and
the emergency call is cancelled.
IMPORTANT: It is recommended to set an emergency
channel individually to provide the certain emergency call
operation.
* Depending on the presetting. Ask your dealer for details.
■Stun function
When the specified ID, set as a stun ID or kill ID, is received,
the stun function is activated.
When the stun ID is received, the transceiver becomes unus-
able. Entering of the password (p. 10) or receiving a specified
ID, set as a revive ID, is necessary to operate the transceiver
again in this case.
When the kill ID is received, the transceiver switches to the
cloning required condition. Cloning the transceiver is neces-
sary to operate the transceiver again in this case.
Stun function is also available with the MDC 1200 signaling
system. (p. 16)
■Scrambler function
The voice scrambler function provides private communication
between stations.The optional Rolling or Non-rolling type can
be available.
qPush [Scrambler] to turn the scrambler function ON.
• “ ” appears.
wPush [Scrambler] again to turn the scrambler function

3BASIC OPERATION
■MDC 1200 system operation
The MDC 1200 signaling system enhances your transceiver’s
capabilities. It allows PTT ID*, Emergency signaling, and re-
ceiving Radio Check. Also, the dispatcher can stun and revive
transceivers on the system.
* When [PTT] is pushed and/or released, the transceiver transmits
your station ID.
DTransmitting an Emergency Call
The MDC 1200 system’s Emergency feature can be ac-
cessed using the [Emergency] key (p. 9). The transceiver will
send an Emergency MDC 1200 system command once, or
repeatedly for a programmed number of times until it receives
the acknowledgement signal.
The emergency call can be transmitted without a beep sound
depending on how the emergency function is programmed.
Ask your dealer for details.
DReceiving an Emergency Call
qWhen an emergency call is received;
• Beeps sound.
• The calling station alias and “EMG EMG” are displayed alter-
nately.
wTurn power OFF, change the channel, push [PTT] for reply-
ing the call, etc. to stop the beep and display indication.
DReceiving a Stun and Revive
The dispatcher can send MDC 1200 system signals that will
stun or revive your transceiver. If a Stun command is received
that matches your station ID, the transceiver will display
“SORRY” (default) and you can not receive or transmit. When
a Revive command is received that matches your station ID,
normal operation is restored.
