SAFETY CHECK-OUT
After correcting the original service problem, perform the follow-
ing 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
TheAC 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 0.5 mA (500 microampers).
Leakage current can be measured by any one of three methods.
1. A commercial leakage tester, such as the Simpson 229 or RCA
WT-540A. Follow the manufacturers’ instructions to use these
instruments.
2. A battery-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-operatedAC voltmeter. 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
apassiveVOM thatissuitable. Nearly allbatteryoperateddigital
multimeters that have a 2 VAC range are suitable. (See Fig.A)

NOTES ON HANDLING THE OPTICAL PICK-UP
BLOCK OR BASE UNIT
CHUCK PLATE JIG ON REPAIRING
On repairing CD section, playing a disc without the CD lid, use
Chuck Plate Jig.
• Code number of Chuck Plate Jig: X-4918-255-1
The laser diode in the optical pick-up block may suffer electro-
static breakdown because of the potential difference generated by
the charged electrostatic load, etc. on clothing and the human body.
During repair, pay attention to electrostatic breakdown 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 emis-
sion, observe from more than 30 cm away from the objective lens.
This Compact Disc player is classiffied as a
CLASS 1 LASER product.
The CLASS 1 LASER PRODUCT table is
location on the rear exterior.

LASER DIODE AND FOCUS SEARCH OPERATION
CHECK
1. Turn POWER switch on with to disc inserted and make Func-
tion switch to CD position.
2. Open the lid for CD.
3. Turn on S801 as following figure.
4. Press the ·button.
5. Confirm the laser diode emission while observing the objecting
lens. When there is no emission,Auto Power Control circuit or
Optical Pick-up is broken.
Objective lens moves up and down three times for focus search.
HOW TO CHANGE THE FM CERAMIC FILTERS
This model is used two ceramic filters of CF1, 2 and CF3.
Therefore, the ceramic filter must change two pieces together since
it's supply two pieces in one package as a spare parts.
