° Material: AlGaAs
Wavelength: 760-800mm
Emission duration: Continuous
Laser Output: 0.2mW
* This output is the value measured at distance 1.6mm from the objective lens surface on the optical pick-up block.
Classification: CLASS 1
5. WARNING FOR SERVICING
WARNING: When servicing, do not approach the LASER exit with the eye too closely. In case it is necessary to confirm
LASER beam emission, be sure to observe from a distance of more than 30cm from the surface of the
objective lens on the optical pick-up block.
VARNING: Nar underhaliningsarbeten utférs, narma dig férsiktigt och se inte pa laserutstralningen pa for nare hall. Ifall det

Wi SERVICING NOTES
Disconnect
power
supply
cord
before
separating
cabinet
for
servicing
as
you
may
experience
an
electric
shock.
Avoid
repairing
under
direct
sunshine
and
heat
which
may
cause
cabinet,
transistor
and
IC
to
be
transformed
or
misoperate.
Use
a
soft
cotton
swab
moistened
with
warm
water
or
neutral
cleaner
when
parts
of
a
unit
need
to
be
cleaned.
Be
sure
to
use
identical
and
standardized
replacement
parts,
especially
for
critical
parts
marked
by
A\
in
the
circuit
diagram
and
arts
list.
‘avoid repairing the set near a TV or any other magnetic forces.
Disconnect
the
plug
from
wall
socket
during
electric
storm
to
reduce
the
risk
of
damage.
Be
careful
of
electrostatic
damage
when
replacing
the
control
IC
such
as
u-COM,
LSI
and
pick-up.

HANDLING THE OPTICAL PICK-UP
*
The
laser
diode
in
the
optical
pick
up
may
suffer
electrostatic
breakdown
because
of
potential
static
electricity
from
clothing
and
your
body.
The following method is recommended.
Place
a
conductive
sheet
on
the
workbench.
(The
black
sheet
used
as
wrapping
for
repair
parts.)
Place
the
set
on
the
conductive
sheet
so that
the
chassis
is
grounded
to
the
sheet.
Place
your
hands
on
the
conductive
sheet.
(This
gives
them
the
same
ground
as
the
sheet.)
Remove
the
optical
pick
up block.
Perform work on top of the conductive sheet.
Be
careful
not
to
let
your
clothes
or
any
other
static
sources
touch
the
unit.
9 FON>
Be sure to put on a wrist-strap grounded to the sheet.
Be
sure
to
lay
a
conductive
sheet
made
of
copper
etc.
which
is
grounded
to
the
table.
