Situation : SCU Does Not Register or Report

On application of external power, the SCU should register with the satellite and send a report.

Note: The SCU must be visible to the satellite to register with the network and

registration normally takes a few minutes.

If the SCU fails to register or report:

• Ensure that the SCU has a clear line-of-sight to the satellite. The SCU must operate outdoors and

be unobstructed by buildings, forest canopy, and rock cuts.

• Check that no objects or debris are touching the SCU antenna and blocking transmission.

• Verify with your supplier that the SCU is assigned to your account and registered (that it is

sending and receiving) and that the OG2 network is operating properly.

Replace the SCU if the earlier checks fail to uncover the problem.
