SERVICING NOTES
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 0.5 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-operated A C voltmeter. The “limit” indication
is 0.75 V, so analog meters must have an accurate low-voltage
scale. The Simpson 250 and Sanwa SH-63T rd are examples of
a passive VOM that is suitable. Nearly all battery operated digital
multimeters that have a 2 V AC range are suitable. (See Fig. A)

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
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 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 emission, 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.
CAUTION
Use of controls or adjustments or performance of procedures
other than those specified herein may result in hazardous radiation exposure.

CHECK
1. Turn POWER switch on with to disc inserted and make Function 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 Po wer Control circuit or
Optical Pick-up is broken.
Objective lens moves up and do wn 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.

Notes on Adjustment
1. Perform adjustment in test mode.
After adjustments, be sure to release test mode.
2. Perform adjustments in the order given.
3. Use the disc (YEDS-18. Part No. 3-702-101-01) only when so
indicated.
How to Put the Set into Test Mode
1. Disconnect an AC plug cord.
2. Turn on the power while shorting the test point (TEST1). (Connect the AC plug cord)
3. Opening the shorted test point puts the set into Test Mode.

How to Release the Test Mode
1. Press the [OPERATE] button to put the set into the standby
status.
2. Finally, disconnect and connect the AC plug cord.
Before Begining Adjustment
Put the set into test mode and perform the following checks.
Repair if there are any problems.
• Sled Motor Check
Press the +, = buttons and confirm that the optical pick-up
moves smoothly from the innermost to outermost circumference
and back smoothly and with no catching or abnormal noises.

• Focus Search Check
1. Press the ( button. (Focus search operation is performed continuously.)
2. Look at the optical pick-up objective lens and confirm that it
moves up and down smoothly, when no catching or abnormal
noises.
3. Press the p button.
Confirm that focus search operation stops. If it does not , press
the p button again longer.

Focus/Tracking Gain Adjustment
A frequency responce analyzer is necessary in order to perform
this adjustment exactly.
However, this gain has a margin, so even if it is slightly off, there
is no problem. Therefore, do not perform this adjustment.
Focus/tracking gain determines 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, mechanical shock and skipping occurs
more easily.
• When gain adjustment is off, the symptoms below appear.
