Do not use solvents such as benzene, thinner, commercially available cleaners or anti-static spray intended for vinyl LPs. Do not expose the CD to direct sunlight or heat sources such as hot air ducts, nor leave it in a car parked in direct sunlight.

On safety

The unit is not disconnected from the AC power source (mains) as long as it is connected to the wall outlet, even if the unit itself has been turned off. Unplug the system from the wall outlet (mains) if it is not to be used for an extended period of time. To disconnect the cord (mains lead), pull it out by the plug. Never pull the cord itself. Should any solid object or liquid fall into the component, unplug the stereo system and have the component checked by qualified personnel before operating it any further. The AC power cord must be changed only at the qualified service shop.

Cleaning the cabinet

Use a soft cloth slightly moistened with mild detergent solution.
To save a tape permanently
To prevent a tape from being accidentally recorded over, break off the cassette tab from side A or B as illustrated.

Detector slots

On placement
Place the stereo system in a location with adequate ventilation to prevent heat build-up in the stereo system. Do not place the unit in an inclined position. Do not place the unit in locations where it is; Extremely hot or cold Dusty or dirty Very humid Vibrating Subject to direct sunlight

Tab of side B

Tab of side A Side A Break off the cassette tab of side A

On operation

If the stereo system is brought directly from a cold to a warm location, or is placed in a very damp room, moisture may condense on the lens inside the CD player. Should this occur, the system will not operate properly. Remove the CD and leave the system turned on for about an hour until the moisture evaporates. When you move the system, take out any discs. If you have any questions or problems concerning your stereo system, please consult your nearest Sony dealer.
If you later want to reuse the tape for recording, cover the broken tab with adhesive tape. However, be careful not to cover the detector slots which allow the tape player to automatically detect the type of tape.
Precautions (continued) Before placing a cassette in the tape deck
Take up any slack in the tape. Otherwise the tape may get entangled in the parts of the tape deck and become damaged.

Troubleshooting

If you run into any problem using this stereo system, use the following check list. First, check that the power cord is connected firmly and the speakers are connected correctly and firmly. Should any problem persist, consult your nearest Sony dealer.
