Caring for your compact disc player, DVD player and discs
D Extremely high temperatures can keep your compact disc
player and DVD player from working. On hot days, use the
air conditioning to cool the vehicle interior before you use
the players.
D Bumpy roads or other vibrations may make your compact
disc player and DVD player skip.
D If moisture gets into your compact disc player and DVD
player, the players may not play even though they appear
to be working. Remove the disc from the player and wait
until it dries.
CAUTION
Compact disc players and DVD players use an invisible
laser beam which could cause hazardous radiation
exposure if directed outside the unit. Be sure to operate
the players correctly.
