PANEL MIC LEVEL ADJUSTMENT (INTERNAL)
The microphone preamplifier for the panel microphone has an internal gain
adjustment control. This gain can be adjusted for different operating conditions.
As shipped from the factory, the control is set to minimum gain such that the
panel microphone and a headset microphone have the same volume when
worked at about 2 in. (5.08 cm).
To adjust the panel microphone gain, you must open the unit. Ground yourself
and tools before touching the circuit board, as circuit boards can be damaged by
static electricity. Remove the top cover of the unit, and locate the jumper labeled
“R161.” It is located on the leftmost side of the circuit board, toward the front of
the unit when facing it. Use a small screwdriver to turn the control clockwise to
increase gain or counterclockwise to decrease gain.
