yYou cannot use a DualDisc in the CD
player. If you insert a DualDisc into the
player, the disc may not come out again,
possibly causing the player to malfunc-
tion. y In cold and/or rainy weather, dew can
form inside the CD player, preventing nor-
mal operation. If this happens, eject the
CD and wait for the player to dry out. y Skipping may occur when the CD player
is subjected to severe vibration (for exam-
ple, when the vehicle is driven on a roughsurface). y To remove a disc from the case, press
the center of the case and hold both edg-
es of the disc. If the disc surface is
touched directly, contamination could
cause poor tone quality. Do not touch thedisc surface. y
Use a clean disc whenever possible. If
there are deposits, wipe the disc surface
from the center outward with a dry, soft
cloth. Be sure not to use a hard cloth, thin-
ner, benzene, alcohol, etc. y Do not use any disc that is scratched,
deformed, or cracked. Also, do not use
any disc that has a non-standard shape
(for example, a heart shape). Malfunctions
or problems might result. y A disc is vulnerable to heat. Never keep
it either in places exposed to direct sun-
light, near heaters or in vehicles parked in
the sun or on hot days.
