BASIC OPERATION
■ MDC 1200 system operation
The MDC 1200 signaling system enhances your transceiver's
capabilities. It allows PTT ID*, Emergency signaling, and re-
ceiving Radio Check. Also, the dispatcher can stun and revive
transceivers on the system.
* When [PTT] is pushed and/or released, the transceiver transmits
your station ID.
D Transmitting an Emergency Call
The MDC 1200 system's Emergency feature can be ac-
cessed using the [Emergency] key (p. 9). 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.

D Receiving a Stun and Revive

that matches your station ID, the transceiver will display
"SORRY" (default) and you can not receive or transmit. When
a Revive command is received that matches your station ID,
normal operation is restored.
