DVB3030/DVB3030L Digital Video Broadcast Modulator Maintenance
TM052 - Rev. 3.5 6-1
Section 6 – Maintenance
6.0 Periodic Maintenance
The DVB3030 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 DVB3030. If this does not cure the
problem, wiring or power should be suspect.
There is no external fuse on the DVB3030. The fuse is located on the power supply assembly
inside the case, and replacement is not intended in the field.
