Troubleshooting
Most difficulties in audio systems are the re-
sult of incorrect connections, or improper
control settings. If you encounter problems, iso-
late the area of the difficulty, check the con-
trol settings, determine the cause of the fault
and make the necessary changes. If you ex-
perience 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
display 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 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 RCC-1055 dis-
play 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 play-
ing side of the disc for contamination or dam-
age. 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 au-
dio cables between the RCC-1055 and the
amplifier to be sure they are properly con-
nected.
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 prob-
lem persists it could be caused by vibrations
reaching the RCC-1055. Sound vibrations, es-
pecially 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 po-
sition farther away from other electrical com-
ponents, especially power amplifiers which
have large power transformers. Other devices
that commonly cause interference are fluores-
cent lights and light dimmer controls.
