6.1.1 Front Panel LED Indicators
The behavior of the eight front panel LEDs adjacent to the keypad
indicate the operational status of the CDM-700, and are described below
in Table 6-1.
Table 6-1. Front Panel LED Indicators

Transmitter is currently on. This indicator reflects the actual condition of the
transmitter, as opposed to the programmed condition.
Off Transmitter is currently OFF.
Remote/EDMAC
Green

Local monitoring is possible, but no local control
Off The Unit is in Local Mode – remote monitoring is possible, but no remote control

IMPORTANT
In general, the Alarm relay state will reflect the state of the Front Panel LEDs. For
instance, if the Unit Status LED is red, the Unit Alarm relay will be active, etc. The
one exception is the Transmit Traffic relay. This will only be activated if a Transmit
Traffic Fault exists – it does not reflect the state of the Tx carrier.
