@
Cleaning
Compact
Discs
Before

wipe
off
the
playing
surface
with
a
soft
cloth
to
remove
dust
and
other
soil.
Wipe
the
surface
in
straight
lines
from
the
center
of
the
disc
outward,
not
in
a
circular
motion
as
you
would
with
a
phonograph
record.
Do
not
use
benzene,
chemical
cleansers
or
phonograph
record
cleaning
solutions

avoid
static
electricity
prevention
solutions
since
they
can
damage
the
surface-of
Compact
Discs.
Problems
Caused
by
Dew
Dew
can
form
inside
a
Compact
player
when
it
is
brought
from
a
cold
environment
into
a
warm
room,
when
:a
room
is
rapidly
heated
and
if
a
player
is
left
in
a
humid
environ-
ment.
This
dew
can
prevent
the
laser
pickup
from
reading
the
data
contained
in
the
pits
in
the
disc
surface.
If
the
player
does
not
operate
properly
because
of
dew,
remove
the
disc
and
leave
the
player’s
power
switch
on
for
about
one
hour
to
remove
all
moisture.
