1. RECEIVE LEVEL ADJUST. Use to adjust the receive
level of the base station two-way radio when there is no
external volume control on the base station radio.
CAUTION: The receive level is set at the factory and
should be adjusted only if the remote radio does not
have its own volume adjustment. The default is 12
o’clock (1/2 rotation).
2. TRANSMIT LEVEL ADJUST. Use transmit level adjust
to set the level of the intercom’s audio as heard at the
remote station walkie-talkie.
3. TRANSMIT ON LIGHT. The light illuminates when a
call signal is being sent from the intercom system.
4. AUDIO LEVEL LIGHTS. Red and green lights indicate
the audio level in the intercom system. Use these
indicators to adjust the volume control on the base
station walkie-talkie to match the wired intercom levels.
The red light illuminates when the signal is too high.
Note that proper intercom levels cause the red light to
illuminate about 10 percent of the time.
