Trouble shooting
Once configured, the module should not need further operational adjustments
unless signal or system requirements change. However, status LEDs are provided to
assist in the unlikely event that problems with configuration or module performance
arise.
In normal operation the following green LEDs should be illuminated, VD, AD, RA1,
RA2, Lock1, Lock2 and Power. No red or yellow LED should be permanently lit, but
may flash briefly during power-up.
