Signal Strength (RSSI) / Mode and Status LEDs
The Signal Strength (RSSI) / Mode and Status LEDs normally display the module’s signal
strength. LED 1 (red LED on the left) will be lit to indicate that the display is in RSSI mode,
and the other LEDs indicate signal strength (lowest to highest, from left to right) between
the module and the receiving tower.
The signal strength RSSI LEDs will indicate regardless of whether the SIM is activated.
(If the SIM is not activated, the red FAULT LED will be lit).
This allows you to immediately determine if the desired mounting location has sufficient
signal strength for proper operation.
If the SIM is not activated, you can determine the signal strength by simultaneously
pressing the MODE and TAMPER buttons. For proper operation, look for at least 3 bars
lit solid.
