e Carrying for discs
Be

to
handle
discs
properly
as
described
in
the
‘‘Discs’’
section
of
this
booklet.
SET-UP UPON UNPACKING
When
the
CD-73
is
shipped,
two
screws
are
inserted
in
its
bottom
to
prevent
the
drawer
from
moving
during
shipment.
Remove
these
screws
before
using
the
unit.
Also,
be
sure
to
remove
the
protective
paper
from
the
disc
clamper.
DISCS
Note
how
the
surfaces
of
discs
gleam
with
all
the
colors
of
the
rain-
bow.
This
is
because
of
light
diffraction
caused
by
the
discs’
micron-
size
tracks.
The
CD-73
Compact
Disc
Player
uses
a
beam
of
laser
light
to
read
audio
information
from
these
tracks;
thus,
the
discs
are
never
subjected
to
stylus
wear
as
is
the
case
with
conventional
record
players.
@ Handle discs carefully to avoid scratching their surfaces.
@ Keep the surfaces of discs clean.
This
is
important,
because
there
may
be
as
many
as
15
billion
bits
of
information
recorded
on
their
surfaces
and
excessive
dust
can
result
in
intermittent
interruption
of
sound.
Remove
ordi-
nary
dust
and
fingerprints
by
breathing
on
the
disc
and
wiping
it
gently
with
a
clean
cotton
handkerchief
or
gauze.
® To maintain the quality of your discs, avoid placing them in
locations such as the following,
@
Locations
which
are
exposed
to
direct
sunlight
or
heat
(such
as
radiators)
e Locations with high concentrations of dust or humidity
e@ Places which may be exposed to water, such as near windows
e
Place
your
discs
in
their
protective
cases
when
they
are
not
in
use.
