VOX SELECTION MODE
The Voice Activated Transmission (VOX) function allows your voice to activate signal
transmission automatically when the FR1438-2 is used with a hands free microphone/
headset (FRS-BHST). It also allows hands free use when a microphone/headset is
not being used without having to use the PTT Button (4). When in the VOX mode a
short beep will sound after the termination of any VOX generated transmission. To
access the VOX Selection menu:
1. Press the Function Button (12) until the VOX icon blinks and UO appears in the
LCD Panel (8).
2. Press the Up Button (10) or the Down Button (11) to select from high, low or off.
The high or low setting determines VOX response sensitivity.
3. Press the Enter Button (13) to confirm your selection.
VOX RECOVERY TIME SELECTION MODE

transmitting and receiving.
3. Press the Enter Button (13) to confirm your selection.

the best value to suit your speaking habits.
To turn off the VOX feature, enter the VOX selection mode and
