MDC 1200 SYSTEM OPERATION
D
Transmitting an Emergency Call
When
[Emergency]
, described in the instruction manual, is
held down for the specified time period, the MDC 1200 emer-
gency signal is transmitted once or repeatedly* on the emer-
gency channel. When no emergency channel is specified, the
signal is transmitted on the operating channel.
* When the Repeat Cancel function is ON, the transceiver cancels
repeating after receiving an acknowledgement.
When the Repeat Cancel function is OFF, the transceiver repeats
calling according to the number of repeat cycles, even after receiv-
ing an acknowledgement.
This function is usable in transceivers whose revision number is 3.0
or later. Ask your dealer for details.
If you want to cancel the emergency call, hold down the key
again before transmitting the call.
The emergency call may be transmitted without a beep
sounding, and the LCD lighting, depending on the presetting.
(Silent operation)
The transceiver can also be programmed to keep the micro-
phone open during an emergency call, to allow monitoring of
the situation.
Ask your dealer for details.
IMPORTANT:
Setting an emergency channel individually to
provide the certain emergency call operation is recom-
mended.

Status message transmission
The status message can be automatically transmitted when
the transceiver is turned ON.
- Set the status message to be transmitted in the ‘Power ON Sta-
tus’ item.
