NGC unit, test the AC charger/power supply.
6.5.7.1
1) Check the input AC voltage to the enclosure power supply. Be certain the
2) If the primary input AC voltage level is correct, and there is no DC output from
the power supply, replace the F1 charger fuse (see

communications that can be used between the NGC and a radio receiver are:
•
•
•
The radio/modem may be powered one of two ways: always on or switched. The
specific system setup will determine what steps are needed to power the
