VOX Feature
The built-in Voice Activated Circuit (VOX) feature enables you to transmit automatically
by speaking on the microphone of a VOX headset (not supplied) without pressing the
PTT button.
To activate this feature:
1. Turn off the radio. Open the SPKR/MIC
cover and plug in a VOX headset
(not supplied).
2. Turn on the radio while pressing the
call/vox button. The VOX icon appears.
3. To set the VOX sensitivity level, press the
call/vox and scan/vibrate buttons
simultaneously until the VOX icon and
number indicator begin to flash.
4. Within 10 seconds, select one of the level numbers,
1 (the lowest sensitivity) ~ 9 (the highest), using the up or down button.
5. To complete the entry, press the scan/vibrate or call/vox button. Now the radio is
ready for automatic transmission.
6. To deactivate the VOX feature, turn the radio off, then on again while pressing
the call/vox button. The VOX icon is no longer displayed.
Don’t press the PTT button while VOX is activated.
