Troubleshooting Some Typically Encountered Problems - Motorola MSAT-G2 Installation Manual

5) Troubleshoot by component
Does the problem sound TU-related, antenna-related, handset-related or external
equipment-related? Swap out a suspect component into a known working system
(i.e. if the TU is suspect, try it out with a known working antenna and handset).
It is highly recommended that a complete working satellite radio (TU, Handset,
and AU) be part of any troubleshooting kit.

Troubleshooting Some Typically Encountered Problems:

1) MT will not power up.
Start by checking that the power supply is working properly.
Check the power level supplied by the cable going into the TU.
Check that the power cable is securely connected to the TU.
2) Commissioning Fails
Is there sufficiently high enough signal strength?
Check the antenna for line-of-sight.
Check that the correct SASK, PFC & CFC are entered.
Check the TU ESN – is this the correct TU?
Check that the account is active and that the unit is in ready to commission status.
3) Signal Strength low/intermittent/none
Check the antenna cable connection both at the TU and antenna.
Check that the cable is not damaged in any way (pinched, cut etc.).
