microphone in place.
12. VOX Control (KB-702GM/KB-802GM-IM only): When the panel microphone
is selected on the KB-702GM/KB-802GM-IM, the VOX control should be adjusted
for proper operation. This control is located to the right of the panel mic
connector. Use a narrow flat blade screwdriver such as a greenie or tweaker for
this adjustment. When the adjustment is correctly set, the VOX light illuminates
amber when speaking into the panel microphone. Turning the control clockwise
makes the KB-702GM/KB-802GM-IM more sensitive to your voice. The VOX
feature can be disabled by turning the VOX control fully counterclockwise.
