If the memory portion of the DVD is
transparent or translucent, do not use the
disc.
Transparent
A new DVD may have rough edges on
its inner and outer perimeters. If a disc
with rough edges is used, proper setting
will not be possible and the DVD player
will not play the DVD. In addition,
the disc may not eject resulting in a
malfunction. Remove the rough edges
in advance by using a ball-point pen
or pencil as shown below. To remove
the rough edges, rub the side of the pen
or pencil against the inner and outer
perimeter of the DVD.
When driving over uneven surfaces, the
sound may jump.
DVDs bearing the logo shown in the
illustration or DVD-R/DVD R/DVD-
RW/DVD RW written with video data
(DVD-Video/DVD-VR fi le) can be
played.
Use discs that have been legitimately
produced. If illegally-copied discs such
as pirated discs are used, the system may
not operate properly.
Be sure never to touch the signal surface
when handling the DVDs. Pick up a
DVD by grasping the outer edge or the
edge of the hole and the outer edge.
Do not stick paper or tape on the DVD.
Avoid scratching the reverse side (the
side without a label). The disc may not
eject resulting in a malfunction.
Dust, fi nger smudges, and dirt can
decrease the amount of light refl ected
from the signal surface, thus affecting
sound quality. If the DVD should
become soiled, gently wipe it with a soft
cloth from the centre of the DVD to the
edge.
Do not use record sprays, antistatic
agents, or household spray cleaners.
Volatile chemicals such as benzine and
thinner can also damage the surface
of the DVD and must not be used.
Anything that can damage, warp, or fog
plastic should never be used to clean
DVDs.
The DVD player ejects the DVD if the
DVD is inserted upside down. Also dirty
and/or defective DVDs may be ejected.
Do not insert cleaning discs in the DVD
player.
Do not insert any disc with a peel-off
seal affi xed to it.
