Cautions Regarding Compact Disc Handling - Pioneer XR-J11 Operating Instructions Manual

CAUTIONS REGARDING COMPACT DISC HANDLING
CARE OF DISCS____
• With this unit, use discs which display the mark shown in Fig. 1
(Optical digital audio discs)
• When holding discs, do not touch their signal surfaces. Hold the
edges, or one edge and the center hole. See Fig. 2.
• Do not affix labels or adhesive tape to the label surfaces. Also, do
not scratch or damage the label. See Fig. 3.
• Discs rotate at high speed inside the unit Do not use damaged
(cracked or warped) discs. See Fig. 4.
CLEANING DISCS_
• The presence of fingerprints or smudges on the surface of the disc
will not directly affect the recorded signals; but depending on the
degree of contamination, the brightness of the light reflected from
the signal surfaces may be reduced, causing degradation of sound
quality.
Always keep your discs clean by wiping them gently with a soft
cloth from the inner edge toward the outer perimeter. See Fig. 5.
• If a disc becomes very dirty, wet a soft cloth in water. After
wringing it out well, wipe the dirt away gently, and then remove
any water drops with another soft dry cloth.
• Do not use record cleaning sprays of anti-static agents on discs.
Also, never clean discs with benzene, thinner or other volatile
solvents which may cause damage to the disc surface. See Fig. 6.
STORING DISCS
• Discs are made of the same kind of plastic used for conventional
analog audio records. Be careful not to allow discs to warp; always
store discs in their cases vertically, avoiding locations with high
heat or humidity, or extremely low temperatures. Avoid leaving
discs in cars and on the seats being exposed to direct sunlight can
be harmful. See Fig. 7.
• Always read and abide by the precautionary notes listed on the
disc labels.
CD LENS CLEANER
The player's pickup lens should not become dirty in normal use, but
if for some reason it should malfunction due to soiling, ask your
nearest PIONEER authorized service center. Lens cleaners for CD
players are commercially available, but special care should be
exercised in their use since some may cause damage to the lens.
