LED Indicators
Table 3 provides details of the LED indicators on the ExtendAir (TDD) radios. Note that there are two
LEDs, top and bottom, associated with each connector. See Alarms Page
for information on how the
Exalt GUI displays LED status.
RESET Button
There is only one external control on the ExtendAir (TDD) radio system, a button labeled “RESET”
which is located on the Power Injector. This button performs two functions: critical system parameter
reset and summary alarm information.
Use a connector cover on all unused connectors for weatherproofing. The connector covers
are included in the accessory kit. Use a safety ring on each connector to secure the connector
covers.
