Settings
Setting Options
- Several adjustments to the SON104 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 “Rx” Adjust 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.
