once every 30 hours of playing/recording time by using a com-
mercial tape head demagnetizer. Read the demagnetizer’s in-
structions carefully before use.
●
In order to ensure proper operation of the CD player, preven-
tative maintenance (cleaning of the Laser Pick-up lens) should
be performed periodically in order to keep the lens dust-free.
