Troubleshooting; Power Indicator Is Not Lit; Fuse Replacement; No Sound - Rotel RA-972 Manuel D'utilisation

Troubleshooting

Most difficulties in audio systems are the re-
sult of incorrect connections, or improper
control settings. If you encounter problems,
isolate the area of the difficulty, check the con-
trol settings, determine the cause of the fault
and make the necessary changes. If you are
unable to get sound from the RA-972 refer
to the suggestions for the following conditions:

Power Indicator Is Not Lit

The Power Indicator should be lit whenever
the RA-972 is plugged into the wall power
outlet and the Power Switch is pushed in. If it
does not light, test the power outlet with an-
other electrical device, such as a lamp. Be sure
the power outlet being used is not controlled
by a switch that has been turned off.

Fuse Replacement

If another electrical device works when plugged
into the power outlet, but the Standby Indica-
tor still will not light when the RA-972 is plugged
into the wall outlet, it indicates that the inter-
nal power fuse may have blown. If you believe
this has happened, contact your authorized
Rotel dealer to get the fuse replaced.

No Sound

Check the signal source to see if it is functioning
properly. Make sure the cables from the sig-
nal source to the RA-972 inputs are connected
properly. Be sure the Listening Selector is set
to the proper input. Check the wiring between
the RA-972 and the speakers.
