When loading or removing discs, try not
to touch their playing surfaces.

Cleaning
Fingerprints or other dirt on the disc may
affect sound and picture quality.
To clean your discs, use a soft clean cloth
to wipe them. If necessary, moisten a soft
cloth with diluted neutral detergent to
remove heavy dirt or fingerprints.
Do not wipe in a circular direction (Concentric
scratches in the disc groove tend to cause
noise.)
Gently wipe from the inside to the outer
edge.
Cleaning Care
Use a soft, dry cloth for cleaning. For
stubborn dirt, soak the cloth in a detergent
solution; ring well first and wipe. Use a
dry cloth to wipe it dry. Do not use any
volatile agents such as benzene or paint
thinner, as they may damage the surface
of the player.
Lens cleaner
The player’s pickup lens should not become
dirty under normal use, but is for some
reason it should malfunction due to soiling,
contact your nearest WACA authorized
service center. Lens cleaners are
commercially available, but special care
should be exercised in their use since some
may cause damage to the lens.
