This section discusses unit maintenance and troubleshooting for the DM240XR High-Speed
Digital Modulator.
6.0 Periodic Maintenance
The DM240XR modulator 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 DM240XR. If this does not cure the
problem, wiring or power should be suspect.
There is no external fuse on the DM240XR. The fuse is located on the power supply assembly
inside the case, and replacement is not intended in the field.
