Step 2b – SIM card is not activated
The red LED flashes, the blue LED is off and the signal strength LEDs display the average signal
strength.

FLASHING
In this state, the 3G4010CF/LE4010CF is unable to register to the cellular network because it is
inactive. The signal strength indicated is from any nearby cell tower (including cellular towers
belonging to non-roaming partners) and does not necessarily reflect the signal strength of the
intended network. The 3G4010CF/LE4010CF will remain in this state until the SIM is activated. Once
the SIM is activated, the 3G4010CF/LE4010CF will move to Step 2a.
Step 3 – Carrier scanning due to insufficient signal strength
The 3G4010CF/LE4010CF scans the surrounding network and connects to the carrier to provide a
signal strength of at least 7 CSQ. While this action is being performed, all four LEDs activate to show
a scanning sequence in progress. The LEDs cycle from top to bottom and then bottom to top until
the 3G4010CF/LE4010CF connects to a carrier with a signal strength above 7 CSQ (minimum of
bottom signal strength LED on solid).

Once this is completed, the 3G4010CF/LE4010CF proceeds to Step 4.
Step 4 - Acquire C24 Communications programming
The red LED will be on solid and the blue LED will flash. The flashing of the blue LED indicates that
the 3G4010CF/LE4010CF has requested programming from C24 Communications and is waiting for
a response.

ON
Once remote programming is complete, the blue LED turns solid and the 3G4010CF/LE4010CF
will move to Step 5.
Step 5 – Receiver initialization
The red LED and the blue LED are both solid and the signal strength LEDs are off.
