Voice-Activated Microphone Setup
If you are going to use VOX (Voice Operated Switching), you must adjust the vox level for proper operation. If the vox level
is too low, room noise activates the microphone. If the vox level is too high, the microphone does not activate when you begin
talking.
To check and set the VOX level, do the following:
1. If you are using a headset, tap the headset key twice to turn on headset VOX.
OR
If you are using a panel microphone, tap the panel mic key twice to turn on panel mic vox.
The indicator for the key you tap lights orange when the microphone is off and blinks or turns green when sound is
picked up by the microphone.
2. Position the microphone at its normal operating location.
NOTE: If you are using a headset, put the headset on and position the microphone close to your mouth.
3. Ensure background noise is at a normal operating level. Do not speak into the microphone.
4. Turn the vox trimmer clockwise until the headset or panel mic indicator begins to blinks green (mic activating).
5. Turn the trimmer slowly counter-clockwise until the panel mic indicator shows steady orange (mic off).
NOTE: If you are wearing a headset, make sure that breathing and movement do not cause the panel mic indicator to
blinks green. If they do, adjust the vox control slightly more in the counter-clockwise direction to eliminate
this.
6. Speak into the microphone in a normal voice to verify the headset indicator immediately turns green when you talk.
If it does not, move the microphone closer to your mouth.
NOTE: If you are unable to get satisfactory results, it may be the microphone does not have the directional
characteristics required for the noise level in the room. A directional microphone is recommended when
using vox. Omnidirectional microphones may not produce good results.
Operation
NOTE: A quick-reference to the following operating features can be found on the inside of the back cover (see “Quick
