MAINTENANCE

External care

Internal care

Periodically wipe the cabinet with a soft cloth and a diluted soap solution, then wipe with a dirty cloth.

Do not use chemically treated cleaning cloths or other chemicals.

In order to ensure proper operation of the CD player, pre- ventative maintenance (cleaning of the laser pick-up lens) should be performed periodically in order to keep the lens dust-free. Lens cleaners are commercially available. Con- tact your local CD software dealer for options.
