lowing keys and switches;
Handheld transceivers:
[EMR], [Side1], [Side2], [Side3], [I]*1, [II]*1, [III]*1, [Ω]*1, [≈]*1,
[∫]*1, [√]*1, [APP]*1, [HOME]*1, ABC switch and Toggle
switch.
*1 Available on Simple and 10-key types only
Mobile transceivers:
[UP]*2, [DOWN]*2, [P0], [P1], [P2], [P3] and [P4].
*2Available on 10-key types only
Consult your Icom dealer or system operator for details con-
cerning your transceiver’s programming.
For Handheld transceivers:
❍ABC and Toggle switches
The programmable key functions for the ABC and Toggle
switches are limited. (See p. 10 for details.)
❍Key indicator (Simple and 10-key types only)
If the key indicator shows the programmed function key
name, push the front panel key ([I], [II] or [III]) under the key
indicator to activate the programmed function.
( In the explanations that follow, the function key name for that
key indicator is displayed in double quotation marks; e.g.
“EMR.”)
❍Non-display types
The programmable key functions are limited, and some key
functions operate differently between the Simple and 10-key
types.

nTone Signaling*
When your system employs tone signaling (excluding CTCSS
and DTCS), this call procedure may be necessary prior to
voice transmission. The tone signaling employed may be a
selective calling system, which allows you to call specic
station(s) only and prevent unwanted stations from contact-
ing you.
q Select the desired TX code channel according to your sys-
tem operator’s instructions. (Only Simple and 10-key types)
• This may not be necessary, depending on programming.
• Refer to the right column for the selecting procedure.
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.
nTX Code CH 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], [CH Down] or [CH Up/Down] selects a TX code
channel.
Not available on Non-display types.
USING [TX CODE CH SELECT] :
qPush [TX Code CH Select]— a TX code channel number
(or name) appears.
wPush [CH Up] or [CH Down], or rotate [CH Up/Down] to
select a 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]:
If the transceiver has a [TX Code CH Up] or [TX Code CH
Down] key assignment, the programmed TX code channel
can be selected when pushed.
* These functions are usable with transceivers whose revision
number is 1.7 or later. Ask your dealer for details.

nEmergency transmission
When [Emergency] is pushed and held for the specied time
period*1, the DTMF emergency signal is transmitted once, or
repeatedly*1, on the specied emergency channel.
A repeat emergency signal is automatically transmitted until
turning the transceiver OFF, or pushing [Home]*2.
When no emergency channel is specied, 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 Emergency calls without the beep sounding or
the LCD display lighting.
IMPORTANT: It is recommended to set an emergency
channel individually to provide the certain emergency call
operation.
DNOTES
Depending on the pre-setting, the following functions are au-
tomatically activated. Ask your dealer for details.
• Auto TX function
The transceiver automatically transmits the microphone audio
for the specied time period*1after the emergency call trans-
mission.
- The HM-148G or HM-152 h a n d m i c r o p h o n e is required for Mobile
transceivers.
• Auto RX function
The transceiver stands by in the audible mode for the speci-
ed time period*1, after the emergency call transmission.
*1Depending on the pre-setting. Ask your dealer for details.
*2For only transceivers whose revision number is 1.7 or later.

nMan Down Emergency Call
(Handheld transceivers only)
This function requires the optional UT-124R m a n d o w n u n i t .
When the transceiver has been left in a horizontal position for
the specied time period*, the transceiver enters the emer-
gency mode, and then the countdown starts.
After the specied time period* has passed, an emergency
call is automatically transmitted once, or repeatedly*.
If the transceiver is placed in a vertical position before the
rst transmission, the transceiver exits the emergency mode
and the emergency call is canceled.
*Depending on the pre-setting. Ask your dealer for details.

3MDC 1200 SYSTEM OPERATION
nMDC 1200 system operation
The MDC 1200 signaling system enhances your transceiver’s
capabilities. It allows PTT ID, Selective Calling (SelCall), Call
Alert, Radio Check, Stun, Revive, Status, Messaging and
Emergency signaling. This operation is usable with transceiv-
ers whose revision number is 1.7 or later.
An additional feature of MDC 1200 system found in Icom
transceivers is called aliasing. Each transceiver on the system
has a unique ID number. Aliasing allows the substitution of an
alphanumeric name for this ID number. For transmit, you can
use this alias to select a transceiver to call. For receive, the
alias of the calling station is displayed instead of the ID.
Please note that your dealer has set one of the programma-
ble keys for MDC 1200 system operation.
NOTE: During MDC 1200 system operation, APCO 25
system operation is not usable.
