How to clean the unit
If the control panel is stained, wipe it with a dry
soft cloth such as a silicon cloth.
If it is badly stained, wipe the stain off with a
cloth moistened with neutral cleaner, then
wipe it again with a clean soft dry cloth.
• Applying spray cleaner directly to the unit
may affect its mechanical parts. Wiping the
control panel with a hard cloth or using a
volatile liquid such as thinner or alcohol may
scratch the surface or erases characters.
How to clean the connectors
Frequent detachment will deteriorate the
connectors.
To minimize this possibility, periodically wipe
the connectors with a cotton swab or cloth
moistened with alcohol, being careful not to
damage the connectors.
How to handle discs
When removing a disc from
its case, press down the
center holder of the case and
lift the disc out, holding it by
the edges.
• Always hold the disc by the edges. Do not
touch its recording surface.
When storing a disc in its case, gently insert
the disc around the center holder (with the
printed surface facing up).
• Make sure to store discs in cases after use.
To keep discs clean
A dirty disc may not play
correctly. If a disc does become
dirty, wipe it with a soft cloth in a
straight line from center to edge.
• Do not use any solvents (for
example, conventional record cleaner, spray,
thinner, benzine, etc.) to clean discs.
To play new discs
New discs may have some
rough spots around the inner
and outer edges. If such a disc
is used, this unit may reject the
disc.
To remove these rough spots, rub the edges
with a pencil or ball-point pen, etc.
Do not use the following discs:
Single CD (8 cm disc) Warped disc
Sticker and sticker
residue
Stick-on label
Unusual shape
