MAINTENANCE

H Internal care

I In order to ensure proper operation of the CD player, preventative 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. Contact your local CD software dealer for options.

H External care

I Periodically wipe the cabinet with a soft cloth and dilute soap solution, then wipe with a dry cloth.

I Do not use chemically treated cleaning cloths or other chemicals.
