BASIC OPERATION
■
Emergency Call
The emergency call can be performed with [Emergency] (p. ).
The transceiver will send a 5-tone, DTMF or MDC 1200
emergency signal* one time only or repeatedly on the emer-
gency channel. However, 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.
* Depending on the operating model type.
■
Man Down Emergency Call
This function requires the optional UT-124R
man
down
unit
and can be performed in conventional mode.
The man down emergency call function transmits an emer-
gency call automatically when the transceiver has been left
in a horizontal position.
After the emergency call, the transceiver performs transmis-
sion and reception alternately with receiving a signal and
emitting audio.
When the emergency reset signal is received, the function is
cancelled.
IMPORTANT:
Set an emergency channel individually, to
provide certain emergency call operation is recommended.

tion between stations. The optional Rolling or Non-rolling
