Voice-Activated Microphone (Vox) Setup
If you are going to use vox, you must adjust the vox level for proper operation. If the vox level is too low, room
noise will activate the microphone. If the Vox level is too high, the microphone will not activate when you begin
talking.
Check and set the level as follows:
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. Whichever key you tap, it will glow
orange when the microphone is off and will flicker or turn green when sound is picked up by the micro
phone.
2. Position the microphone at its normal operating location. If you are using a headset, put the headset on and
position the microphone close to your mouth. Insure that background noise is at the normal operating level.
3. Do not speak into the microphone.
4. Check the Headset or Panel Mic key, whichever you are using. If the key is constantly glowing orange, turn
the Vox trimmer clockwise until the key begins to flicker green (mic activating) then turn the trimmer
slightly back in the counterclockwise direction until the Panel Mic key just returns to steady orange (mic
off). If you are wearing a headset, make sure that breathing and movement do not cause the Panel Mic key
to flicker green. If they do, adjust the Vox control slightly more in the counterclockwise direction to
eliminate this.
5. Speak into the microphone in a normal voice, and check that the headset key immediately turns green when
you talk. If it does not, move the microphone closer to your mouth. If you are still unable to get satisfactory
results, it may be that the microphone does not have the directional characteristics required for the noise
level in the room. A directional, or cardioid, microphone is recommended when using Vox. Omnidirectional
microphones mode, the Mic Kill key will be unlit, and in programming mode it will be lit continuously. To
return the MS-2002 to normal operation if it has been left in programming mode, tap the Mic Kill key.
Operation
Note: A quick-reference to the following operating features can be found on the inside of the back cover.
NORMAL VS PROGRAMMING MODE
The MS-2002 has two operating modes: normal operating mode and programming mode. In normal operating
mode, the Mic Kill key will be unlit, and in programming mode it will be lit continuously. To return the MS-2002 to
normal operation if it has been left in programming mode, tap the Mic Kill key.
