DSC 3G4010 Installation Manual page 8

If the signal strength is too low (bottom signal LED off or flashing), the 3G4010 will move to Step 3 and scan for carriers with suf-
ficient signal strength and attach to the carrier. If the 3G4010 is connected to a carrier with sufficient signal strength (minimum of
bottom signal strength LED on solid), it will move to Step 4.
Step 2b – SIM card is not activated
The red LED will flash, the blue LED will be off and the signal strength LEDs will display the average signal strength.

FLASHING
In this state, the 3G4010 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 3G4010 will remain in this state until the SIM is activated. Once the SIM is activated, the
3G4010 will move to Step 2a.
Step 3 – Carrier Scanning due to insufficient signal strength
The 3G4010 will scan the surrounding cellular network and connect to the carrier to provide a signal strength of at least 7 CSQ.
When this action is being performed, all four LEDs will activate to show a scanning sequence. The LEDs will cycle from top to
bottom and then bottom to top. This cycle will continue until the 3G4010 is connected to a carrier with a signal strength above 7
CSQ (minimu of bottom signal strength LED on solid).

Once this is completed, the 3G4010 will move 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 3G4010 has requested
programming from C24 Communications and is waiting for a response.
Red
ON
Once remote programming is completed, the blue LED will switch to solid and the 3G4010 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.
Red
ON
When the 3G4010 sends a request to communicate with the central station, the top signal strength LED will begin flashing.
Red
ON
When the central station communicates back with the 3G4010, the top signal strength LED will turn on solid.
