BASIC OPERATION

MDC 1200 system operation ■

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.

Receiving an Emergency Call D

When an emergency call is received; q

• Beeps sound.

• The calling station alias and “EMG EMG” are displayed alter-

nately.

w Turn power OFF, change the channel, push [PTT] for reply-

ing the call, etc. to stop the beep and display indication.

Receiving a Stun and Revive D

The dispatcher can send MDC 1200 system signals that will

stun or revive your transceiver. If a Stun command is re-

ceived that matches your station ID, the transceiver will dis-

play “SORRY” (default) and you can not receive or transmit.

When a Revive command is received that matches your sta-

tion ID, normal operation is restored.
