MDC 1200 system operation
The MDC 1200 signaling system enhances your transceiver’s
capabilities with PTT ID* and Emergency signaling
.
* When [PTT] is pushed and/or released, the transceiver transmits its
own station ID.
D
Transmitting an Emergency Call
The MDC 1200 system’s Emergency feature can be ac-
cessed using the [Emergency] key (p. 4). The transceiver
will send an Emergency MDC 1200 system command once,
or repeatedly for a programmed number of times, until it re-
ceives an acknowledgement signal.
The emergency call can be transmitted without a beep sound,
depending on the preprogramming. Ask your dealer for de-
tails.
D
Receiving 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 not
receive or transmit. When a Revive command that matches
your station ID is received, normal operation is restored.
