Precautions

• Avoid installing the unit where it would be subject to high
temperatures, such as in direct sunlight or a hot air stream
from the heater, or where it would be subject to dust, dirt, or
excessive vibration.

• Do not turn on the unit if the temperature inside the car is
very high. Always cool down the unit before usage. Parking
your car in direct sunlight will result in a temperature rise.

• If the unit does not turn on, check the connections first. Then
check whether the fuse at the back of the unit is blown.

• Carefully read this manual before using the unit. If you en­counter any problems that are not covered in this manual,
please consult the dealer where you purchased the unit or
the dealer nearest to you.

• This unit has been designed specifically for playback of com­pact discs bearing the

mark. Other discs cannot be

played.

Handling Compact Discs

• Be careful when removing a compact disk after the play-

back is completed because the disk may be extremely hot.

• Do not expose compact discs to direct sunlight or any heat
source.

• Check all compact discs before playing, and discard cracked,
scratched or warped discs.

• Wipe dirty or damp discs outward from the center with a
soft cloth.

• Do not use any solvents such as commercially available
cleaners, antistatic spray, or thinner to clean the compact
discs.
