Vox Circuit Adjustment
NOTE : The unit is shipped from the factory with the VOX
circuit pre-adjusted. Use this procedure only if you encoun-
ter a problem where the VOX circuit does not properly
switch between the operator and customer when they are
talking. In some situations, particularly when ambient noise
levels vary over time, it may be necessary to “touch up” the
VOX adjustments.
1.
Locate the two VOX pots: VOX1 and VOX2. They are
located on the operator assembly side of the unit.
2.
Set VOX1 (top hole) all the way clockwise. Set VOX2
(bottom hole) all the way clockwise
3.
Locate the customer and operator volume controls. they
are located on the operator side of the unit. Set each of
them to the middle of their adjustment range.
4.
Have an assistant talk on the outside microphone and
using the included screwdriver adjust VOX2 (bottom
hole) so that the VOX just triggers and you can be heard
by your assistant on the speaker on the customer side.
Then turn the pot just a little further.
5.
Talk back and forth and adjust VOX1 (top hole) and
VOX2 (bottom hole) very carefully to get the proper
VOX switching action. Be sure to talk directly into the
microphones because they are close talking.
