Check/Resistance
Check
Before
returning
the

to
the
customer,
make
sure
you
make
either
(1)
a
leakage
current
check
or
(2)
a
line
to

resistance
check.
If
the
leakage
current
exceeds
0.5
milliamp,
or
if
the
resistance
from
chassis
to
either
side
of
the
power
cord
is
less
than
240
k
ohms,
the
unit
is
defective.

Handling
the
Laser
Pickup
In
case
of
repair
or
replacement
of
the
Laser
Pickup,
pay
attention
to
the
following
handling
instructions
since
the
laser
diode
in
the
Laser
Pickup
is
not
resistant
to
static
electricity.
(1)
Grounding
When
you
repair
a
Laser
Pickup,
first
ground
the
human
body,
as
well
as
the
measuring
instruments
and
other
tools
(with
particular
caution
to
soldering
iron).
What’s
more,
your
workbench
and
floor
should
desirably
be
grounded
using
conductive
sheet
or
copper
plate.
See
Fig.
1.1.
Note:
Be
careful
so
as
not
to
let
your
clothes
touch
the
Laser
Pickup,
as
static
electricity
on
the
clothes
will
not
be
released
even
if
your
body
is
grounded.

Discharge
of
Electricity
Be
sure
to
discharge
electricity
from
objects
brought
into
contact
with
the
Laser
Pickup
(i.e.,
soldering
iron,
tweezers,
probes,
volt-ohm-meter
probes,
etc.)
before
starting
work
by
contacting
them
with
the
Compact
Dise
Player’s
chassis.
Besides,
never
touch
the
Laser
Pickup
while
power
is
applied.
Soldering
Iron
to
be
Used
The
soldering
iron
for
use
in
repair
work
shoud
be:
(1)
a
ceramic
soldering
iron,
(2)
a
soldering
iron
with
its
metal
part
grounded,
or
(8)
a
soldering
iron
whose
insulation
resistance
after
five
minutes
of
power
application
is
10
M-ohm
or
more
at
500
VDC.
Soldering
should
be
completed
promptly,
at
a
soldering
iron
temperature
of
320°
max
(39
W).
A
soldering
iron
heated
above
this
temperature
can
break
down
the
laser
diode.
