After releasing the PTT or when you stop talking in VOX mod, you and all other recipients will hear a
beep tone.
ADJUSTMENT OF THE VOX SENSITIVITY:
•
Maximum sensitivity (first VOX level) is appropriate for communication in low noise levels. A
low voice signal will activate the transmission.
•
The third VOX level (lowest sensitivity) is appropriate for transmissions in high noise levels and

sensitivity adjustment is dependent upon the actual noise level.
