Emergency Call
When
[Emergency Single]
or
[Emergency Repeat]
(p. 11) is
pushed and held for the specified time period, the emergency sig-
nal (5-tone, DTMF or MDC 1200) is transmitted once or repeatedly
on the emergency channel. A repeat emergency signal is auto-
matically transmitted until it receives the acknowledgement signal.
When no emergency channel is specified, the signal is transmitted
on the previously selected channel.
If you want to cancel the emergency call, push and hold the key
again before transmitting the call.
The emergency call can be transmitted without a beep emission,
and the LCD indication if
[Emergency Single (Silent)]
or
[Emer-
gency Repeat (Silent)]
(p. 11) is pushed.
The transceiver can also be programmed to keep the microphone
open during an emergency call, allowing monitoring of the situa-
tion.
IMPORTANT:
It is recommended to set an emergency channel
individually to provide the certain emergency call operation.
■
DTMF transmission
If the transceiver has
[DTMF Autodial]
assigned to it, the auto-
matic DTMF transmission function is available.
➥
Push
[DTMF Autodial]
to transmit the DTMF code.
