2 Components of Your Device3. System LED indicates the status of the connectivitywith the Sprint network system. Illuminates a steady blue (not blinking) when thebase station is communicating with the system. Illuminates red when a system error is detected.This typically indicates a communication problemwith the Sprint network.4. GPS LED indicates the GPS connection status. Illuminates a steady blue (not blinking) when thebase station has detected a valid GPS signal. Illuminates red when the internal GPS antenna isnot able to detect a stable GPS signal and cannotvalidate accurate time and location information.5. WAN LED indicates the status of the Wide AreaNetwork activity via an active Ethernet connection.It does not detect either an ISP connection or arouter connection to the ISP. Illuminates a steady blue (not blinking) when avalid Ethernet connection is detected. When an invalid Ethernet connection is detected,no illumination occurs.Note: The GPS signal can also be improved by connectingthe external GPS antenna to the base station.If the unit’s GPS signal strength is weak (due tolocation), it is recommended that you either move thebase station near a window or install the external GPSantenna.
