MDC 1200 SYSTEM OPERATION
D Transmitting an Emergency Call
When [Emergency] is held down for the preset time period,
an emergency signal (MDC 1200 system command) is trans-
mitted once, or repeatedly
channel.
A repeat emergency signal is automatically transmitted until
turning the transceiver OFF, or pushing [Home]
When no emergency channel is specified, the signal is trans-
mitted on the previously selected channel.
If you want to cancel the emergency function, hold down
[Emergency] again before transmitting the call.
If your transceiver is programmed for Silent operation, you
can transmit Emergency calls without the beep sounding or
the LCD display lighting.
The transceiver can also be programmed to keep the micro-
phone open during an emergency call, allowing monitoring of
the situation.

IMPORTANT: It is recommended to set an emergency
channel individually to provide the certain emergency call
operation.
