1.1.3 POWER LED
The PWR LED shows that the dc supply is connected to the receiver and that the
microprocessor is not being held in a RESET state.
1.1.4

TX LED

The TX LED illuminates when the transmitter is keyed. It will not illuminate (and an
ALARM cadence will be shown) if the synthesizer becomes unlocked, or the output
amplifier supply is interrupted by the microprocessor.
1.1.5

ALARM LED

The Alarm LED can indicate several fault conditions if they are detected by the self test
program. The alarm indicator shows the highest priority fault present. See Tables 1
and 2.
