SAFETY CHECK-OUT 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 gencrated 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
After correcting the original service problem,
perform the following safty 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.
matter which is included in the repair parts.
The flexible board is easily damaged and should be
handled with care.
LEAKAGE TEST
The AC leakage from any exposed metal part to
earth ground and from all exposed metal part to any
exposed metal part having a retum to chassis, must
not exceed 0.5 mA (S00 microampers). Leakage
current can be measured by any one of three
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
methods. objective lens in the optical pick-up block. There-
fore, when checking the laser diode emission, observe
more than 25 cm away from the objective lens.
1. A commercial leakage tester, such as the
Simpson 229 or RCA WT-540A. Follow the
manufacturers’ instructions to use these instm-
ments. This appliance is classified as a
CLASS 1 LASER product. The
CLASS 1 LASER PRODUCT
MARKING is located on the rear
exterior. ;

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 volt-
meter. The “limit” indication 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)

ELECTRICAL BLOCK CHECKING
Note:
as
CD Block basically constructed to operate without
adjustment. Therefore, check each item in order given.
2. Use YEDS-18 disc (3-702-101-01) unless otherwise
indicated.
3. Use the oscilloscope with more than 10M 22 impedance.

detergent when the signal level is low than specified
value with the following checks.

3. Turned Power switch on and actuate the focus search.
(actuate the focus search when disc table is moving in

4. Check the oscilloscope waveform (S- curve) is
symmetrical between A and B. And confirm peak to

Note :
* Try to measure several times to make sure that
the ratio of A:B or B:A is more than 10:7,
* Take sweep time as long as possible and light up
