Precautions
for
Traverse
Deck
The
laser
diode
in
the
traverse
deck
(optical
pickup)
may
break
down
due
to
potential
difference
caused
by
static
electricity
of
clothes
or
human
body.
So,
be
careful
of
electrostatic
breakdown
during
repair
of
the
traverse
deck
(optical
pickup).
@
Handling
of
traverse
deck
(optical
pickup)
1.
Do
not
subject
the
traverse
deck
(optical
pickup)
to
static
electricity
as
it
is
extremely
sensitive
to
electrical
shock.
2.
To
prevent
the
breakdown
of
the
laser
diode,
an
anti-static
shorting
pin
is
inserted
into
the
flexible
board
(FPC
board).
When
removing
or
connecting
the
short
pin,
finish
the
job
in
as
short
time
as
possible.
3.
Take
care
not
to
apply
excessive
stress
to
the
flexible
board
(FPC
board).
4.
Do
not
turn
the
variable
resistor
(laser
power
adjustment).
It
has
al-
ready
been
adjusted.
®
Grounding
for
electrostatic
breakdown
prevention
1.
Human
body
grounding
Use
the
anti-static
wrist
strap
to
discharge
the
static
electricity
from
your
body.
2.
Work
table
grounding
Put
a
conducive
material
(sheet)
or
steel
sheet
on
the
area
where
the
traverse
deck
(optical
pickup)
is
placed,
and
ground
the
sheet.
Caution:
The
static
electricity
of
your
clothes
will
not
be
grounded
through
the
wrist
strap.
So,
take
care
not
to
let
your
clothes
touch
the
traverse
deck
(optical
pickup).
