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 areturn to chassis, must
not exceed 0.5 mA (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 instru-
ments.
2. Abattery-operated AC miliiammeter. The Data
Precision 245 digital multimeter is suitable for
this job.
3.
Measuring the voltage drop across aresistor by
means of aVOM or battery-operated AC volt-
meter. The “limit” indication is 0.75 V, so
analog meters must have an accurate low-
voltage scale. The Simpson 250 and Sanwa
SH-63Trd are examples of apassive VOM that
is suitable. Nearly all battery operated digital
multimeters that have a2V AC range are
suitable. (See Fig. A)
SERVICING NOTE
NOTES ON HANDLING THE OPTICAL PICK-
UP BLOCK OR BASE UNIT
The laser diode in the optical pick-up block may
suffer electrostatic breakdown because of the poten-
tial 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.
CAUTION
Use of controls or adjustments or performance
of procedures other than those specified herein
may result in hazardous radiation exposure.
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 check-
ing the laser diode emission, observe from more than 30
cm away from the objective lens.

PROTECTION OF EYES FROM LASER BEAM DURING SERVICING
1.Laser Diode Properties
•Material: GaAlAs
•Wavelength: 780 nm
•Emission Duration: continuous
•Laser Output: max. 44.6 /iW*
*This output is the value measured at adistance of
about 200 mm from the objective lens surface on
the Optical Pick-up Block.
2. During service, do not take the Optical Pick-up
Block apart, and do not adjust the APC circuit.
If there is abreakdown in the APC circuit (includ-
ing laser diode), replace the entire Optiocal Pick-
up Block (including APC borad).
This set employs alaser. Therefore, be sure to fol-
low carefully the instructions below when servicing.
CAUTION
Use of controls or adjustments or performance
of procedures other than those specified herein
may result in hazardous radiation exposure.

Focus/Tracking Gain Adjustment
Afrequency response analyzer is necessary in order
to perform this adjustment exactly.
However, this gain has amargine, so even if it is
slightly off, there is no problem. Therefore, this adjust-
ment is not recomended generally to be performed.
Focus/tracking gains determine the pick-up follow-up
(vertical and horizontal) relative to mechanical noise
and mechanical shock when the 2-axis device operate.
However, as these reciprocate, the adjustment is at
the point where both are satisfied.
•When gain is raised, the noise when the 2-axis
device operates increases.
•When gain is lowered, it is more susceptible to
mechanical shock and skipping occurs more easily.
•When gain adjustment is off, the symptoms below
appear.
