MDC 1200 system operation N
The MDC 1200 signaling system enhances your transceiv-
er’s capabilities. It allows PTT ID*, Emergency signaling, and
receiving Radio Check. Also, the dispatcher can stun and re-
vive transceivers on the system.
* When [PTT] is pushed and/or released, the transceiver transmits
your station ID.
Transmitting an Emergency Call D
The MDC 1200 system’s Emergency feature can be ac-
cessed using the [Emergency] key (p. 7). 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.

tion ID, normal operation is restored.
