nProgrammable key functions
The programmable key functions can be assigned to the fol-
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.
*1Available 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
For Handheld transceivers:
❍ABC and Toggle switches
The programmable key functions for the ABC and Toggle
switches are limited. (See page 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 specific
station(s) only and prevent unwanted stations from contact-
ing you.
qSelect 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 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.

select a desired DTMF channel.
ePush [DTMF Autodial] to transmit the DTMF code.
❍For Non-display types
You cannot select a desired DTMF channel. Pushing [DTMF
Autodial] transmits the DTMF code programmed in DTMF
channel 1.

nEmergency transmission
When [Emergency] is held down for the preset time period,
the DTMF emergency signal is transmitted once, or repeat-
edly*1, on the specified emergency channel.
A repeat emergency signal is automatically transmitted until
turning the transceiver OFF, or pushing [Home]*2.
When no emergency channel is specified, the signal is trans-
mitted on the previously selected channel.
If you want to cancel the emergency call, hold down [Emer-
gency] 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.
*1Depending on the presetting.
*2For only transceivers whose revision number is 1.7 or later.
DNOTES
Depending on the presetting, the following functions are au-
tomatically activated.
• Auto TX function
The transceiver automatically transmits the microphone audio
for the preset time period after the emergency call transmis-
sion.
- The HM-148G or HM-152 hand microphone is required for Mobile
transceivers.
• Auto RX function
The transceiver stands by in the audible mode for the preset
time period, after the emergency call transmission.

nMan Down Emergency Call
(Handheld transceivers only)
This function requires the optional UT-124R man down unit.
When the transceiver has been left in a horizontal position for
the preset time period, the transceiver enters the emergency
mode, and then the countdown starts.
After the preset time period has passed, an emergency call is
automatically transmitted once, or repeatedly, depending on
the presetting.
If the transceiver is placed in a vertical position before the
first transmission, the transceiver exits the emergency mode
and the emergency call is canceled.

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.
Set one of the programmable keys for MDC 1200 system op-
eration.
NOTE: During MDC 1200 system operation, APCO 25
system operation is not usable.
