Maintenance
■Cleaning the unit
Dust the unit with a soft cloth. For stubborn dirt, use a soft cloth dampened with a weak solution of mild detergent and water. Dry the unit immediately afterwards with a clean, dry cloth.
•Do not use thinners, alcohol, or other chemical solvents.
•If you are using chemical cleaning cloth, follow the instructions for using the cloth carefully.
■Cleaning the optical pickup lens of the CD player
A dirty optical pickup lens on the CD player may cause the player to skip or become unable to play back. In this case, remove the power cord from the AC outlet, then use a cotton swab to lightly wipe the dirt off the lens or use a blower to blow the dust off.
•Do not apply too much force when you clean the lens. Otherwise, the CD player may 
malfunction.
■Cleaning the head of the cassette tape recorder
Rec./Playback head | Capstan |
As you use the cassette tape recorder, magnetic particles accumulate on the recording/playback head, leading to a greatly diminished sound quality, decreased volume, or incomplete recording. Use a commercially available cleaning kit to clean the erase head, record/playback head, pinch rollers and capstans every 10 hours of operation.
