LED Indicators
Table 3 provides details of the LED indicators on the ExtendAir (TDD) Series radios. Note that there
are two LEDs, labeled top and bottom, associated with each connector. See
information on how the Exalt GUI displays LED status.
RESET Button
There is only one external control on the ExtendAir (TDD) Series radios 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 the reset function if the IP address and/or passwords are lost. Use the following steps to perform a
critical parameter reset:
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.
