■ Man Down Emergency Call
The man down emergency call function transmits an emergency
call automatically, after the transceiver laying down in a horizontal
position for a pre-set time period. (The optional UT-113
MAN DOWN
UNIT is required.)
After the emergency call, the transceiver performs transmission and
reception alternately with the following conditions:
- Transmits the microphone signals.
- Receives the signal and emits audio.
When the emergency cancel code is received, the function is can-
celled.
IMPORTANT!: Set an emergency channel individually, to provide
certain emergency call operation is recommended.
