Network – Indicates a successful connection to the cellular network with an IP address given and a channel acquired.
Signal – Light shows the strength of the signal and may be nearly solid (strong signal) or flashing (weaker signal). A slow flash indicates a very weak signal.
Activity – Lights will flash as data is transferred to and from the PinPoint modem on the remote network.
Power – Indicates the power adapter is connected and there is power getting to the Raven XT.
The Reset button (on the left side of the Raven XT) has two functions. If it is quickly depressed and released, the modem will simply power cycle the internal hardware. If, however, the reset is depressed and held for several seconds (count 10 slowly, and wait for the power light to go off after the light pattern stops), the ALEOS configuration settings will return to the factory
defaults.

The LEDs on the front of the modem will respond in different patterns to indicate modem states.
