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.
