To
engineers
in
charge
of
repair
or
inspection
of
our
products.
Before
repair
or
inspection,
make
sure
to
follow
the
instructions
so
that
customers
and
Engineers
in
charge
of
repair
or
inspection
can
avoid
suffering
any
risk
or
injury.
1.
Use specified parts.
The
system
uses
parts
with
special
safety
features
against
fire
and
voltage.
Use
only
parts
with
equivalent
characteristics
when
replacing
them.
The
use
of
unspecified
parts
shall
be
regarded
as
remodelling
for
which
we
shall
not
be
liable.
The
onus
of
product
liability
(PL)
shall
not
be
our
responsibility
in
cases
where
an
accident
or
failure
is
as
a
result
of
unspecified
parts
being
used.
Place
the
parts
and
wiring
back
in
their
original
positions
after
replacement
or
re-wiring.
For
proper
circuit
construction,
use
of
insulation
tubes,
bonding,
gaps
to
PWB,
etc,
is
involved.
The
wiring
connection
and
routing
to
the
PWB
are
specially
planned
using
clamps
to
keep
away
from
heated
and
high
voltage
parts.
Ensure
that
they
are
placed
back
in
their
original
positions
after
repair
or
inspection.
If
extended
damage
is
caused
due
to
negligence
during
repair,
the
legal
responsibility
shall
be
with
the
repairing
company.
Check for safety after repair.
Check
that
the
screws,
parts
and
wires
are
put
back
securely
in
their
original
position
after
repair.
Ensure
for
safety
reasons
there
is
no
possibility
of
secondary
problems
around
the
repaired
spots.
‘
If
extended
damage
is
caused
due
to
negligence
of
repair,
the
legal
responsibility
shall
be
with
the
repairing
company.
Caution
in
removal
and
making
wiring
connection
to
the
parts
for
the
automobile.
Disconnect
the
battery
terminal
after
turing
the
ignition
key
off.
If
wrong
wiring
connections
are
made
with
the
battery
connected,
a’short
cirtuitard/or
fire
may
occur.
If
extensive
damage
is
caused
due
to
negligence
of
repair,
the
legal
responsibility
shall
be
with
the
repairing
company.
Cautions
regarding
chips.
Do
not
reuse
removed
chips
even
when
no
abnormality
is
observed
in
their
appearance.
Always
replace
them
with
new
ones.
(The
chip
parts
include
resistors,
capacitors,
diodes,
transistors,
etc).
The
negative
pole
of
tantalum
capacitors
is
highly
susceptible
to
heat,
so
use
special
care
when
replacing
them
and
check.the
operation
afterwards.
Cautions
in
handling
flexible
PWB
Before
working
with
a
soldering
iron,
make
sure
that
the
iron
tip
temperature
is
around
270°C.
Take
care
not
to
apply
the
iron
tip
repeatedly
(more
than
three
times)
to
the
Same
patterns.
Also
take
care
not
to
apply
the
tip
with
force.
Turn
the
unit
OFF
during
disassembly
and
parts
replacement.
Recheck
all
work
before
you
apply
power
to
the
unit.
Cautions
in
checking
that
the
optical
pickup
lights
up.
The
laser
is
focused
on
the
disc
reflection
surface
through
the
lens
of
the
optical
pickup.
When
checking
that
the
laser
optical
diode
lights
up,
keep
your
eyes
more
than
30cms
away
from
the
lens.
Prolonged
viewing
of
the
laser
within
30cms
may
damage
your
eye-sight.
Cautions
in
handling
the
optical
pickup
The
laser
diode
of
the
optical
pickup
can
be
damaged
by
electrostatic
charge
caused
by
your
clothes
and
body.
Make
Sure
to
avoid
electrostatic
charges
on
your
clothes
or
body,
or
discharge
static
electricity
before
handling
the
optical
pickup.
ORB 4375R
9-1. Laser diode
The
taser
diode
terminais
are
shorted
for
transportation
in
order
to
prevent
electrostatic
damage.
After
replacement,
open
the
shorted
circuit.
When
removing
the
pickup
from
the
mechanism,
short
the
terminals
by
soldering
them
to
prevent
this
damage.
9-2. Actuator
The
actuator
has
a
powerful
magnetic
circuit.
If
a
magnetic
material
is
put
close
to
it.
Its
characteristics
will
change.
Ensure
that
no
foreign
substances
enter
through
the
ventilation
slots
in
the
cover.
9-3. Cleaning the lens
Dust
on
the
optical
lens
affects
performance.
To
clean
the
lens,
apply
a
small
amount
of
isopropyl
alcohol
to
lens
paper
and wipe
the
lens
gently.

to
be
careful
in
handling.
6-2.When
disassembling,be
sure
to
turn
off
the
power.
Disconnecting
a
connector
during
power-on
may
destroy
the
intemal
IC.
7.Precautions
for
handling
the
pickup
7-1.Destruction
due
to
surge
current
or
static
electricity
if
a
large
current
flows
to
the
LD
even
for
a
very
short
Period,
deterioration
is
promoted
by
a
strong
light
emitted
by
itself,or
it
is
destroyed.
See
to
it
that
the
LD
drive
circuit
will
not
be
exposed
to
a
Surge
Current
caused
by
a
switch
and
others.
if
you
handle
it
carelessly,
it
will
be
destroyed
instantaneously
by
static
electricity
applied
form
a
hu-
man
body.
The
terminals
of
the
LD
have
been
shorted
in
order
to
protect
them
against
electrostatic
destruction
Caused
by
transportation
upon
shipment.To
make
Safety
doubly
sure,earth
a
human
body,
instruments,and
jigs
without
fail
when
installing.
It
is
recommended
to
spread
@
ground
mat
on
a
work
bench
or
the
floor
for
grounding.To
open
the
shorted
parts,use
a
soldering
iron
after
insert-
ing
a
connector.Use
the
soldering
iron
whose
metallic
part
is
earthed
or
whose
insulation
resistance
is
10M
_
ohm
or
more(500C
DC)in
Sminutes
after
turing
on
the
power,and
whose
temperature
at
its
tip
is
320°C
or
less
(30W),,and
work
quickly.
Depending
on
mechanism,when
rmaving
the
flexible
P.W.B.,
short
it.
7-2.2-axis
block
Actuator
The
actuator
has
a
powerful
magnetic
circuit.If
a
magnetic
substance
is
put
close
to
it.its
characteristics
will
change.Also
see
to
it
that
no
foreign
substances
will
enter
through
the
clearance
of
the
cover.
Cleaning
the
lens
Adherence
of
dust
to
the
objective
reduces
performance.To
clean
the
lens,apply
a
small
amount
of
isopropylalcohol
to
lens
paper
and
wipe
the
lens
gently.
7-3.Handling
a)When
handling
the
pickup
drive
unit,hold
the
resin
mold
chassis.
b)Note
that
if
the
circuitry
of
the
printed
circuit
board
is
directly
touched
by
a
hand
or
other
substances,the
LD
may
be
deteriorated.
C)If
you
directly
touch
the
pins
of
the
flexible
connector
with
hand,the
LD
will
be
deteriorated.When
removing
the
mechanism
from
the
set,be
fully
careful
in
handling.
@
DURING
REPAIR.OR
INSPECTION,OBSERVE
THE
FOLLOWING
1.Use
specified
parts.
The
system
uses
parts
with
special
safety
characteristics
against
flame
and
voltage.Use
only
parts
with
equivalent
characteristics
when
replacing
them.
2.Place
the
parts
and
wiring
back
in
their
original
positions
—
after
replacement
or
re-wiring.
For
proper
circuit
construction,use
of
insulation
tubes,
bonding,
gaps
to
P.W.B.
etc.is
involved.
The
wiring
connection
and
routing
to
the
P.W.B.
are
specially
de-
vised
using
clamps
to
keep
away
from
heated
and
high-
voltage
parts.So,make
sure
to
replace
them
back
in
their
Original
positions
after
repair
or
inspection.
3.Check
for
safety
after
repair.
Check
that
the
Screws,
parts,and
wires
are
put
back
Securely
in
their
original
position
after
tepair.And
make
sure
for
safety
reasons
there
is
no
possibility
of
second-
ary
ploblems
around
the
repaired
spots.
.
4.Cautions
regarding
chips.
Do
not
reuse
removed
chips
even
when
no
abnormality
is
observed
in
their
appearancé.Always
replace
them
with
new
ones.(The
chip
parts
include
resistors,
condensers,
diodes,
transistors,
etc.).
The
negative
pole
of
tantalum
condensers
is
highly
susceptible
to
heat,so
USe
special
care
when
replacing
them,and
check
opeéra-
tion
afterward.

P.W.B.
Before
working
with
a
soldering
iron,
make
sure
that
the
iron
tip
temperature
is
around
270°C
.Take
care
not
to
apply
the
iron
tip
repeatedly(more
than

take
care
not
to
apply
