The basic operation of the CarrierWave Digital Radio can be checked by viewing the LED
indicators on the front panel. Normally, only green LEDs should be lit. A yellow LED indicates
potential system degradation, though the link is still active and operational. A red LED is an
alarm indicator. If it is lit, it indicates a potential problem in the radio system. Refer to Figure 2-3
