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 experience problems

with the RCC-1055, refer to the suggestions

for the following conditions:

Display Is Not Lit

The Disc, Track and Time indicators in the dis-

play should be lit whenever the power switch

of the RCC-1055 is pushed in. If the display

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 RCC-1055 display

will not light when 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.

Disc Does Not Play

If a disc does not begin playing when the Play

button is pressed, open the disc tray and be

sure the disc is loaded with the label side up.

If a disc is properly loaded, inspect the playing

side of the disc for contamination or damage.

If the disc is dirty, clean it as described in the

Handling Compact Discs section. If a disc is

damaged it should be replaced.

No Sound

Check the input selector on the ampliﬁer to be

sure it is properly set. Check the tape monitor

switches to be sure they are properly set. Check

other signal sources to be sure the ampliﬁer

is operating properly. Finally check the audio

cables between the RCC-1055 and the ampliﬁer

to be sure they are properly connected.

Sound Skips

If the sound from the RCC-1055 skips or jumps

around, the disc may be defective or dirty. If

the disc is clean, try another disc. If a problem

persists it could be caused by vibrations reach

ing the RCC-1055. Sound vibrations, especially

from a subwoofer, can interfere with the laser

reading a disc surface. Move the RCC-1055 to

a more stable surface, or to a location farther

away from the speakers.

Hum

Hum is caused by electrical interference from

other devices. It is most often picked up by the

audio signal cables. Use high-quality cables.

Low quality cables often have inadequate

shielding. Check to be sure the cables are

solidly connected to both the RCC-1055 and

the ampliﬁer. Try moving the cables to a position

farther away from other electrical components,

especially power ampliﬁers which have large

power transformers. Other devices that com

monly cause interference are ﬂuorescent lights

and light dimmer controls.
