Replacement
of
the
pickup
assembly
@
Before
removing
the
pickup
assembly
be
sure
to
solder
-bridge
where
indicated
in
the
inset
(Fig.
4-1)
to
prevent
the
laser
diode
from
being
electrostatically
damaged.
After
replacing
the
pickup
assembly,
be
sure
to
unsolder
the
antistatic
bridge.
Or
else
the
laser
diode
does
not
function.
@
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.
4-2.
*
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.
4-3.
Be
particularly
careful
not
to
touch
the
actuator,
photosensor
and
LD
plate
and
do
not
apply
force
to
them.
@Don’t
touch
the
plated
portion
of
the
flat
cable
end
directly
with
fingers.
@Use
care
not
to
break
the
flat
cable.
@
Soldering
must
be
done
quickly
at
less
than
30W,
320°C.
@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.
@If
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.
