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.
