BIIS OPERATION
■
Man Down Emergency Call
The optional UT-124
man
down
unit
is required for this func-
tion.
The man down emergency call function transmits an emer-
gency call automatically, when the transceiver has been left
in a horizontal position.
This function can be performed for both 5-tone and MSK
channels.
After the emergency call, the transceiver performs transmis-
sion and reception alternately with the following conditions:
- Transmits the microphone signals.
- Receives the signal and emits 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.
