WITH  MARK  
!
  ON  THE  SCHEMATIC  DIAGRAMS  AND  IN
THE  PARTS  LIST  ARE  CRITICAL  TO  SAFE  OPERATION.

PART  NUMBERS  APPEAR  AS  SHOWN  IN  THIS  MANUAL  OR

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 AC 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 a
passive VOM that is suitable. Nearly all battery operated digital
multimeters that have a 2 V AC range are suitable.  (See Fig. A)

Note on chip component replacement
• Never reuse a disconnected chip component.
• Notice that the minus side of a tantalum capacitor may be dam-
aged by heat.

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.
NOTES  ON  HANDLING  THE  OPTICAL  PICK-UP
BLOCK  OR  BASE  UNIT
CAUTION
Use of controls or adjustments or performance of procedures
other than those specified herein may result in hazardous
radiation exposure.
This Compact Disc player is classified as a CLASS 1
LASER product.
The CLASS 1 LASER PRODUCT label is located on the
bottom exterior.
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
LASER  DIODE  AND  FOCUS  SEARCH
OPERATION  CHECK
1. Open the CD lid.
2. Turn on S401 as following figure.
3. Confirm that 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 once for the focus search.
Insert a precision
screwdriver and
push S401

instruction manual.
Setting the Clock
and Date
1
Plug in the clock radio.
The display will flash “AM 12:00” or “0:00”.
2
Press CLOCK for a few seconds.
You will hear a beep and the year will start to
flash in the display.
3
Press  TIME SET + or  until the correct
year appears in the display.
4
Press CLOCK once.
5
Repeat steps 3 and 4 to set the month,
day, hour, and minute.
After setting the minute, press CLOCK to start
the counting of the seconds, and you will
hear two short beeps.
• To display the year and date, press SNOOZE/
DATE/SLEEP OFF once for the date, and within
2 seconds press it again for the year. The
display shows the date or year for a few
seconds and then changes back to the current
time.
• To set the current time rapidly, hold down
TIME SET + or .
• The clock system varies depending on the
model you own.
12-hour system: “AM 12:00” = midnight
24-hour system: “0:00” = midnight
• In step 5, when you press CLOCK after the
minute setting to activate the clock, the seconds
start counting from zero.
To change the display to the
daylight saving time (summer time)
indication
Press D.S.T./SUMMER T.
” is displayed and the time indication
changes to summer time.
To deactivate the summer time function, press
D.S.T./SUMMER T. again.
