Several adjustments to the 210 intercom are required. When connecting to a mobile radio it will be necessary to
make both transmit and receive audio adjustments.
Warning
These adjustments must be performed by a qualified radio technician. Failure to perform
these adjustments may result in problems hearing or transmitting radio signals when using
the intercom system.
RX
The receive audio adjustment is a rotational adjustment of the audio gain from the radio. When making this
adjustment, set your mobile radio volume to the normal volume level used without an intercom installed. The
audio level should be adjusted with other intercom users for quality audio mixing.
Transmit Audio Gain Jump
The transmit audio gain jump switch is an incremental gain increase of the audio broadcast through the radio.
The gain is increased when the switch is in the "up" position and decreased in the "down" position. The
Transmit Audio "TX" should be used initially for adjustment and the Transmit Audio Gain jump used only if
required.
Intercom Audio Gain Jump
The intercom audio gain jump switch is an incremental gain increase of the intercom sound level. Each headset
is also equipped with an independent volume control. If an overall higher intercom sound level is desired, the
intercom audio gain jump switch may be used. The gain is increased when the switch is in the "up" position
and decreased in the "down" position.
TX
The transmit audio adjustment is a rotational adjustment of the audio broadcast through the radio. Adjust the
radio transmit sound level to eliminate clipping and provide quality audio mixing.
After these adjustments are made, the holes may be sealed using plugs (provided).
