MDC 1200 OPERATION
■ MDC 1200 system operation
The MDC 1200 signaling system enhances your transceiver’s
capabilities. It allows PTT ID, Selective Calling, CallAlert,
Radio Check, Stun, Revive, Status, Messaging and
Emergency signaling. Also, the dispatcher can stun and
revive transceivers on the system.
An additional feature of MDC 1200 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 programmable keys (IC-F70 series: [EMERGENCY], [UP], [DOWN],
[MONITOR], [P0], [P1], [P2] and [P3], IC-F1700 series:
[UP]*, [DOWN]*, [P0], [P1], [P2], [P3] and [P4]) for MDC
1200 operation.
* IC-F1810, IC-F1821/D, IC-F2810 and IC-F2821/D only

PTTID Calls
The transceiver can send an MDC 1200 signal that includes
PTTID when [PTT] is pushed (beginning of transmission) and
released (end of transmission). If a PTTID call is received, the
transceiver will display the calling station ID (or alias) and
emit a beep*.
*Depends on the setting.
DD
Emergency Calls
The MDC 1200 Emergency feature can be accessed using
the [Emergency Single] or [Emergency Repeat] key
(described in the instruction manual). The transceiver will
repeatedly send an Emergency MDC 1200 command for a
programmed length of time until it receives an acknowledgement signal.
The emergency call can be transmitted without a beep emission and LCD indication change depends on the setting.
With MDC 1200 Emergency, the transceiver can also be programmed to keep the microphone open during an emergency
call, allowing monitoring of the situation.
Ask your dealer for details.
