Palsonic DVD7500 - Manual (Page 35)

Fingerprints or stains on the discs surface
will directly affect signal recording and result in
poor picture quality. Therefore, use a soft cloth
and wipe in a circular manner from the centre to
the outer edges when cleaning the disc.
Do not keep the disc in direct sunlight, near a heat
source, in dusty places or near moisture (kitchen,
bathroom). Keep the disc vertically in the disc
storage case. Heavy objects on the disc case will
cause deformation of the disc.
Do not touch the surface.
Do not add labels or adhesive tapes on discs.
If the surface of your disc is very dirty, wipe the
disc with a moist cloth. Finally use a dry soft cloth
to remove all the water stains.
Never use electrostatic prevention products or
solutions which contain benzene, thinner or any
other vaporising substances, as they may damage
the disc surface.
