■MDC 1200 system operation
The MDC 1200 signaling system enhances your transceiv-
er’s capabilities. It allows PTTID*, Emergency signaling, and
receiving a Radio Check. Also, the dispatcher can stun and
revive transceivers on the system.
An additional feature of the MDC 1200 system in Icom trans-
ceivers is called aliasing. Each transceiver on the system has
a unique ID number. Aliasing allows substituting an alphanu-
meric name for the ID number. When transmitting, you can use
this alias to select a transceiver to call. When a call is received,
the alias of the calling station is displayed instead of the ID.
*When [PTT] is pushed or released, the transceiver transmits your
station ID.
NOTE: During MDC 1200 system operation, IDAS opera-
tion capability is disabled.
■Receiving a call
DReceiving an Emergency Call
qWhen an emergency call is received:
• Beeps sound.
• The calling station ID (or alias) and “EMG EMG” are alternately
displayed.
w To stop the beep and display indication, turn OFF the
power, change the channel or push [PTT].
DReceiving a Stun and Revive
The dispatcher can send MDC 1200 system signals that
will stun or revive your transceiver. If a Stun command that
matches your station ID is received, the transceiver will dis-
play “SORRY” (default) and you cannot receive* or transmit.
When a Revive command that matches your station ID is
received, normal operation is restored and “SORRY” disap-
pears.
(* Except Revive command signals)

2MDC 1200 OPERATION
■Transmitting a call
DPTTID Calls
The transceiver can send an MDC 1200 system signal that
includes PTTID when [PTT] is pushed (begin transmitting)
and released (stop transmitting). If a PTTID call is received,
the transceiver will display the calling station’s ID (or alias)
and sound a beep.* (*Depending on the preprogramming.)
DTransmitting an Emergency Call
When [Emergency] (described in the instruction manual) is
held down for a specified time period,* the emergency signal
is once or repeatedly transmitted on the specified emergency
channel.
When no emergency channel is specified, the call is
transmitted on the operating channel.
The repeat emergency signal is automatically transmitted
until you turn OFF the power.
Depending on the preprogramming, receiving an
acknowledgement may cancel the transmission.
If you want to cancel the Emergency function, hold down
[Emergency] for the preprogrammed time period again before
transmitting the call.
If your transceiver is programmed for Silent operation, you
can transmit emergency calls without the beep sounding and
the LCD display changing.
IMPORTANT: Setting an individual emergency channel is
recommended for dependable emergency call operation.
*Depending on the preprogramming, the following functions can be
automatically activated. Ask your dealer for details.
DNOTES
• Auto TX function
After an emergency call transmission, audio from the
microphone is automatically transmitted for a specified time
period.
• The HM-148G or HM-152 hand microphone is required.
• Auto RX function
After an emergency call transmission, the transceiver stands
by in the audible mode for a specified time period.
