• For channel B: Move the jumper plug so that it covers pins 1 and 2.
This causes talk signal activation to interrupt the program audio.
In the default position, the jumper plug covers pins 2 and 3, which causes
call signal activation, rather than talk signal activation, to interrupt the
program audio.

PANEL MIC LEVEL ADJUSTMENT (INTER-
NAL)
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.
