DD2401 Satellite Demodulator Maintenance
MN-DD2401 - Rev. G 6-1
Maintenance and Troubleshooting 6
6.0 Periodic Maintenance
The DD2401 Demodulator requires no periodic field maintenance procedures. Should a unit be
suspected of a defect in field operations after all interface signals are verified, the correct
procedure is to replace the unit with another known working DD2401. If this does not cure the
problem, wiring or power should be suspect.
There is no external fuse on the DD2401. The fuse is located on the power supply assembly
inside the case, and replacement is not intended in the field.
