■ Man Down Emergency Call

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.
