Fault (RCVR)
This indicates a receive port fault. A fault condition can exist if a receiver port goes to un-squelch (loss of status
tone or COR detect) but no audio is detected for a period of time indicating a fault condition. For the transmitter
port the red LED indicates TX activity.
Green
= Receive
This indicates a receive port has gone to the un-squelch condition (status tone drops or COR detected). There
is no green state indicator for the transmitter port.
Blue
= Voted
This indicates a receive port is voted. There is no blue state indicator for the transmitter port.
Off
= Idle
This indicates a squelch status (status tone being detected or no COR detected) on a receiver port. For the
transmitter port this indicates no TX activity.
