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 S501 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 S501.

SECTION 1

GENERAL

Setting the Clock

and Date

1Set the alarm setting dial to ALARM

MODE OFF.

2Plug in the clock radio.

The display will flash “AM 12:00”or “0:00”.

3Press CLOCK for a few seconds.

You will hear a beep and the year will start to

flash in the display.

4Press CLOCK + or –until the correct

year appears in the display.

5Press CLOCK once.

6Repeat steps 4and 5to 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

CLOCK + 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 6, when you press CLOCK after the

minute setting to activate the clock, the seconds

start counting from zero.

•When the alarm setting dial is set to ALARM

TIME SET A or B, the clock cannot be set.

To change the display to the

daylight saving time (summer time)

indication

Press D.S.T./SUMMER T.

“s”is displayed and the time indication

changes to summer time.

To deactivate the summer time function, press

D.S.T./SUMMER T. again.
