■ Internal care
● 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.
