Clearing FL Display

Customization

To clear all customized displays, turn the RC-1090 on. Then press the Listening Selec- tor Phono button together with the Recording Selector Off button. This will return all displays to their original settings.

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 RC-1090, refer to the suggestions for the following conditions:

Standby Power Indicator Is Not Lit

The Standby Power Indicator should be lit whenever the RC-1090 is plugged into the wall power outlet. 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, and the Standby Indi- cator still will not light when the RC-1090 is plugged into the wall outlet, 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 re- placed.

No Sound

Check the signal source to see if it is functioning properly. Make sure the cables from the sig- nal source to the RC-1090 inputs are connected properly. Be sure the Listening Selector is set to the proper input. Check the power ampli- fier for power and proper operation. Check all the wiring between the RC-1090 and the power amplifier, and the power amplifier and speakers.
