Discs
¢ Only use compact discs (optical digital audio discs) bearing the mark
shown below. (Fig. 1)
Be sure never to touch the signal surface when handling discs.
Pick up discs by grasping the outer edges or the edge of the hole and
the outer edge. (Fig. 2) (Fig. 3)
© Do not affix paper or tape, and avoid scratching the side of the disc
which contains the label (contents of disc). (Fig. 4)
e The disc revolves at high speed within the player unit, so defective
(cracked or badly bent) discs should not be used. (Fig. 5) (Fig. 6)
¢ Dust and/or finger smudges will have no direct effect on the signal
recorded on the disc, but dirt can decrease the amount of light reflected
from the recorded surface, thus affecting sound quality. If the disc
should become soiled, gently wipe the surface with a soft lint-free cloth,
wiping from the center of the disc to the edge. (Fig. 7)
¢ Do not use record sprays or antistatic agents. Such volatile chemicals
as benzine and thinner can also damage the surface of the disc and
should not be used. (Fig. 8)
e As with traditional audio records, compact discs are made of plastic.
To avoid warping, keep the discs in their cases and do not store them
in places exposed to direct sunlight. (Fig. 9)
