Precautions

If your car was parked in direct sunlight resulting in a considerable rise in temperature inside the car, allow the unit to cool off before operating it. If no power is being supplied to the unit, check the connections first. If everything is in order, check the fuse. If no sound comes from the speakers of a two-speaker system, set the fader control to the center position. If your car is equipped with a power antenna, note that it will extend automatically while the unit is operating. If you have any questions or problems concerning your unit that are not covered in this manual, please consult your nearest Sony dealer.
Before playing, clean the discs with an optional cleaning cloth. Wipe each disc from the center out. Do not use solvents such as benzine, thinner, commercially available cleaners or antistatic spray intended for analog discs.

Notes on moisture condensation
On a rainy day or in a very damp area, moisture may condense on the lenses inside the CD player. Should this occur, the unit will not operate properly. In this case, remove the disc and wait for about an hour until the moisture evaporates.

When you play 8 cm CDs

A dirty or defective disc may cause sound dropouts while playing. To enjoy optimum sound, handle the disc as follows. Handle the disc by its edge. To keep the disc clean, do not touch the surface.

Maintenance

Fuse replacement
When replacing the fuse, be sure to use one that matches the amperage described on the fuse. If the fuse blows, check the power connection and replace the fuse. If the fuse blows again after replacement, there may be an internal malfunction. In such a case, consult your nearest Sony dealer.
Do not stick paper or tape on the labeled surface.

Fuse (10 A)

Do not expose the discs to direct sunlight or heat sources such as hot air-ducts, or leave them in a car parked in direct sunlight where there can be a considerable rise in the temperature inside the car.
