Troubleshooting

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

Power Indicator Is Not Lit

The Power Indicator and the basic items in the Display window should be
lit whenever the unit is plugged into the wall power outlet and the Power
button is pushed in. If it does not light, test the power outlet with another
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 Power Indicator of the unit does not light when plugged into the
same outlet and the Power Switch is pushed in, it indicates that the internal
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 signal source to the amplifier inputs are connected
properly. Be sure the Listening Selector is set to the proper input. Check
the wiring between the amplifier and the speakers.
