CARE AND MAINTENANCE
CARE AND CLEANING
All care and cleaning operations should be carried out with the unit unplugged from the
mains power.
The surface of the unit can be cleaned with a barely damp cloth and then dried carefully. Never
use abrasives, abrasive cloths or chemical solvents.
Compact Disc Care
To remove a disc from its storage case, press down on the center of the case and lift the disc
out, holding it carefully by the edges.
Finger prints and dust should be carefully wiped off the disc’s recorded surface with a soft cloth.
Unlike conventional records, compact discs have no grooves to collect dust and microscopic
debris, so gently wiping with a soft cloth should remove most particles. Wipe in a straight line
from the inside to the outside of the disc. Small dust particles and light stains will have
absolutely no effect on reproduction quality.
Clean the disc periodically with a soft, lint-free, dry cloth. Never use detergents or abrasive
cleaners to clean the disc. If necessary, use a CD cleaning kit. Never write on or stick any labels
to the surface of compact discs.
Care of the cabinet
If the cabinet becomes dusty, wipe it with a soft dry dust cloth. Do not use any wax, polish
sprays or abrasive cleaners on the cabinet.
Caution
Never allow any water or other liquids to get inside the unit while cleaning.
