SAFETY CHECK-OUT
After correcting the original service problem, perform the
following safety check before releasing the set to the customer:
Check the antenna terminals, metal trim, "metallized" knobs, screws,
and all other exposed metal parts for AC leakage. Check leakage as
described below.
LEAKAGE TEST
The AC leakage from any exposed metal part to earth ground
and from all exposed metal parts to any exposed metal part having
a return to chassis, must not exceed 0.5mA (500 microampers).
Leakage current can be measured by any one of three methods.
1. Acommercial leakage tester, such as the Simpson 229 or RCA
WT-540A. Follow the manufacturers’ instructions to use these
instruments.
2. Abattery-operated AC milliammeter. The Data Precision 245
digital multimeter is suitable for this job.
3. Measuring the voltage drop across a resistor by means of a
VOM or battery-operated AC voltmeter. The "limit" indica-
tion is 0.75V, so analog meters must have an accurate low-
voltage scale. The Simpson 250 and Sanwa SH-63Trd are
examples of a passive VOM that is suitable. Nearly all battery
operated digital multimeters that have a 2V AC range are
suitable. (See Fig.A)

NOTES
ON
HANDLING
THE
OPTICAL
PICK-UP
BLOCK
OR
BASE
UNIT
The
laser
diode
in
the
optical
pick-up
block
may
suffer
electrostatic
break-down
because
of
the
potential
difference
generated
by
the
charged
electrostatic
load,
etc.
on
clothing
and
the
human
body.
During
repair,
pay
attention
to
electrostatic
break-down
and
also
use
the
procedure
in
the
printed
matter
which
is
included
in
the
repair
parts.
The
flexible
board
is
easily
damaged
and
should
be
handled
with
care.
NOTES
ON
LASER
DIODE
EMISSION
CHECK
The
laser
beam
on
this
model
is
concentrated
so
as
to
be
focused
on
the
disc
reflective
surface
by
the
objective
lens
in
the
optical
pick-up
block.
Therefore,
when
checking
the
laser
diode
emission,
observe
from
more
than
30
cm
away
from
the
objective
lens.
