  • Page 109: Chapter 6. Maintenance And Troubleshooting

    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.
