Diagnostic LED descriptions
At power up, all communicator LEDs activate for several seconds, indicating proper insertion.
The Signal LEDs then turn off until the module registers on the cellular network. Registering a
new module might take up to 2 min.
Check the LED display to ensure a good signal strength level, and adjust the antenna location
as required. The signal strength LEDs momentarily turn off to indicate the module has
measured and updated the signal strength status.
