Displayed on the rear panel of the Mongoose are four status indicators for each connected RAD. If the
Mongoose is communicating properly with a RAD, all four status indicators (Audio Rx, Audio Tx, Comm,
and Power) should be on. e following table details possible causes and solutions for situations in which
one or more of these indicators are off.
Note: It is best to check these indicators in the following order: Power, Comm, Audio Tx, and Audio
Rx. If the power isn’t working, nothing else will work. If the data communications (Comm) isn’t working,
Audio Rx will not work. If Audio Tx isn’t working, Audio Rx will not work.
