MSG GAIN and MIC GAIN
The MSG GAIN (message gain) and MIC GAIN (microphone
gain) potentiometers are factory set and should only be
adjusted by trained technicians with the proper test equipment.
To increase the output of a speaker, change the speaker tap
connection or setting to a higher wattage.
Switch S1
Pressing switch S1 performs a hard reset of the ANS
microprocessor. This is not required during normal operation,
and should only be done at the request of our support
technicians.
