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 two-speaker systems, set the fader control to the centre position. If your car is equipped with a power aerial, note that it will extend automatically while the tuner function is selected. If you have any questions or problems concerning your unit that are not covered in this manual, please consult your nearest Sony dealer.

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.
Before playing, clean the discs with an optional cleaning cloth. Wipe each disc from the centre out. Do not use solvents such as benzine, thinner, commercially available cleaners or antistatic spray intended for analog discs.
DSP/Additional Information
Notes on moisture condensation Notes on handling 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. 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

Use the optional Sony compact disc single adapter (CSA-8) to protect the CD player from being damaged. Do not stick paper or tape on the labeled 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.

Dismounting the unit

Press the clip inside the front cover with a thin screwdriver, and lever the front cover free.

Fuse (3 A)

Repeat step 1 on the left side. The front cover is removed.
Warning Never use a fuse with an amperage rating exceeding the one supplied with the unit as this could damage the unit.
EN Cleaning the connectors
The unit may not function properly if the connectors between the unit and the front panel are not clean. To prevent this, open the front panel by pressing (RELEASE), then detach it and clean the connectors with a cotton swab dipped in alcohol. Do not apply too much force. Otherwise, the connectors may be damaged.
