Scanning NCS
7-2
The communication unit automatically tunes itself to the NCS se-
lected on the System Setup menu. You can, however, tune to another
NCS which has a stronger signal. Scanning is possible only when the
communication unit is IDLE and FELCOM 12 is set to operate as an
Inmarsat-C transceiver.
If the communication unit is not idle, "Communication unit is not
Idle now. Cannot start scan." appears. Press any key to escape then
wait until the unit is in the idle state.
