Lens cleaning instruction
The actuator lens of the unit is an optical component that is exposed to the environment. The
environmental conditions in Juke-Box applications is not comparable with normal home use. For
example, the nicotine from cigarette smoke can soil the lens. This might influence the playability of the
system enormous and cleaning of the lens can be necessary.
Before cleaning the lens, it is advised to make the surface of the lens clean by blowing clean air over it
in order to avoid that little particles make scratches on the lens.
Because the lens is made of synthetic material coated with a special anti-reflectivity layer, the cleaning
must be done with a non-aggressive cleaning fluid. We advice to use the following lens cleaner which
is available in a normal photo shop.
Advised lens cleaner: “
KODAK LENS CLEANER CAT 176 71 36”
The actuator is a very precise mechanical component, which has to follow the tracks on the CD-disc
with a pitch of 1.6 um. This actuator may not be damaged in order to guarantee his full function. We
advice to clean the lens gently (don’t press too hard), with a soft and clean cotton tip moistened with
the special lens cleaner. The direction of movement of the cotton tip should be 90 degree to the radial
tracking movement of the actuator as indicated in the figure below.
Move cotton tip in this direction
