subchapter
J,
based
on
the
Radiation
Control
for
Health
and
Safety
Act
of
1968”,
and
is
classified
as
class
1
laser
product.
There
is
not
hazardous
invisible
laser
radiation
during
operation
because
invisible
!aser
radiation
emitted
inside
of
this
product
is
completely
confined
in
the
protective
housings.
The
label
required
in
this
regulation
is
Shown

CAUTION
@
If
you
remove
the
above-mentioned
housings
under
the
operating
state
of
the
product,
there
is
a
possibility
of
human
access
to
the
invisible
laser
radiation
emitted
from
the
optical
pickup.
Pay
careful
attention,
not
to
jet
the
invisible
laser
beam
enter
into
your
eyes.
@
If
you
find
a
troubled
state
of
the
laser
diode,
change
to
the
specified
new
optical
pickup.
e
If
you
find
a
troubled

1.
Handling
the
pickup
assembly
@
Before
servicing
the
pickup
assembly
be
sure
to
prevent
electrostatic-inducer
destruction
by
grounding
not
only
test
equipment
in
use
but
also
yourself
as
shown
in
Fig.
4-1.
*
Electrostatic
charge
drastically
shortens
the
operating
life
of
the
laser
diode
or
possibly
results
in
its
destruction.
@During
the
transportation,
mounting
and
dismounting
of
the
assembly,
support
with
your
fingers
at
points
A
and
B
as
shown
in
Fig.
4-2.
Be
particularly
careful
not
to
touch
the
actuator,
photosensor
and
LD
plate
and
do
not
apply
force
to
them.
@Don't
disassemble
the
pickup
ass’y.
@Don’t
apply
shock
to
the
pickup
ass’y.
@Don't
place
the
assembly
in
a
place
subject
to
excessive
dust,
heat
or
moisture.

Objective
@laser
beams
are
similar
to
infrared
rays.
Don’t
look
at
the
beams
directly
and
keep
your
eyes
at
least
30cm
away
from
them.
@Don't
touch
the
objective
with
fingers.
@lIf
objective
becomes
dirty,
playback
will
deteriorate.
To
clean
the
objective,
moisten
a
good
cleaning
tissue,
such
as
made
by
KODAK,
in
isopropyl
alcohol
and
wipe
the
objective
gently.
Wipe
off
and
excess
fluid
with
a
dry
cleaning
tissue.
VOLTAGE
CONVERSION
Be
sure
to
remove
the
power
cord
from
the
AC
outlet
before
repositioning
the
voltage
converter
switch.
1.
Locate
the
voltage
selector
on
the
rear
panel.
2.
Using
a
flat-bladed
screwdriver,
set
to
the
appropriate
230
V
or
120
V
position
according
to
your
area.
