can also activate this feature. The transceiver will repeat-

edly send an Emergency MDC 1200 command to the dis-

patcher for a programmed length of time until it receives an

acknowledgement signal.

The emergency call can be transmitted without a beep emis-

sion and LCD indication change depends on the setting.

With MDC 1200 Emergency, the transceiver can also be pro-

grammed to keep the microphone open during an emergency

call, allowing monitoring of the situation.

Ask your dealer for details.

The dispatcher can send MDC 1200 signals that will stun or

revive your transceiver. If a Stun command is received that

matches your station ID, the transceiver will display “SORRY”

and you can not receive or transmit. When a Revive com-

mand is received that matches your station ID, normal opera-

tion is restored.

Pre-programmed message is displayed.
