exceeding the limit for Class 1.
This appliance is classified as
a CLASS 1 LASER product.
The CLASS 1 LASER PR ODUCT MARKING is located on
the rear exterior.
The following
caution label is
located inside of
the unit.
CAUTION
Use of controls or adjustments or performance of procedures
other than those specified herein may result in hazardous radiation exposure.
SAFETY CHECK-OUT
After correcting the original service problem, perform the following safety checks before releasing the set to the customer:
Check the antenna terminals, metal trim, “metallized” knobs, screws,
and all other exposed metal parts for AC leaka ge. Check leakage as
described below.
LEAKAGE
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. F ollow 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 V OM
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 2V AC range are suitable. (See Fig. A)
Notes on chip component replacement
• Never reuse a disconnected chip component.
• Notice that the minus side of a tantalum capacitor may be
damaged by heat.
Flexible Circuit Board Repairing
• Keep the temperature of soldering iron around 270˚C
during repairing.
• Do not touch the soldering iron on the same conductor of the
circuit board (within 3 times).
• Be careful not to apply force on the conductor when soldering
or unsoldering.

NOTES ON HANDLING THE OPTICAL PICK-UP BLOCK
OR BASE UNIT
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 pickup block. Therefore, when checking the laser diode emission, observe from more than 30 cm away from the objective lens.
The emission check enables continuous checking of the S curve.
LASER DIODE AND FOCUS SEARCH OPERATION
CHECK
Carry out the “S curve check” in “CD section adjustment” and check
that the S curve waveform is output three times.

CD-TEXT TEST DISC
This unit is able to display the TEXT data (character information) written in the CD on its fluorescent indicator tube.
The CD-TEXT TEST DISC (TGCS-313:J-2501-126-A) is used for checking the display.
To check, perform the following procedure.
Checking Method:
1. Turn ON the po wer, set the disc on the disc table with the side labeled as “test disc” as the right side, close the front cover, and chuck the
disc.
2. The following will be displayed on the fluorescent indicator tube. (The display switches each time the TIME/TEXT button is pressed.)
Display : Main Artist Test or CD TEXT TEST DISC (Album Title)
3. Press the ” button and play back the disc.
4. The following will be displayed on the fluorescent indicator tube. (If nothing is displayed, press the TIME/TEXT button.)
Display : 1kHz/0 dB/ L&R
5. Rotate ≠ and ± buttons to switch the track. The text data of each track will be displayed.
For details of the displayed contents for each track, refer to “T able 1 : CD-TEXT TEST DISC TEXT Data Contents” and “Table 2 : CDTEXT TEST DISC Recorded Contents and Display”.
Restrictions in CD-TEXT Display
In this unit, some special characters will not be displayed properly. These will be displa yed as a space or a character resembling it. For details,

• Mode which repeatedly changes and plays back discs automatically in the unit.
• It will repeat aging as long as no errors occur.
• If an error occurs during aging, it will stop all servos, motors, etc.
instantaneously, display the error number, and stop operations.
However , the stopping conditions dif fer according to whether the
unit is equipped with the “self-protection function during errors”
described later.
The function serves to maintain the state of the unit when errors
occur.

Special Aging Mode Functions
The aging mode is provided with the following con venient functions
• Disc setting mode (*1)
• Selection of presence of protection function during error (*2)
• Count function of aging cycle (*3)
*1 Disc setting mode:
5 discs are set before setting the aging mode. This mode makes
the setting of these discs more easy.
*2 Self protection function during errors:
Function which voluntarily corrects errors which occur during
normal operations by retries.
If this function is not provided, all operations will be stopped
without retiring. It is suitable for checking errors with low reproducibility.
If this function is provided, and errors can be corrected by retries,
aging will be continued without stopping.
*3 Aging cycle count function:
Functions which displays the number of agings carried out on
the Fluorescent indicator tube in numbers. One aging cycle consists of five discs.

Perform this adjustment after completing all adjustments of the
mechanism section.
If not performed accurately, the presence of the disc may not be
detected properly.

Procedure:
1. Connect the oscilloscope to Pins 1, 2, and 4 of CN506 of the
MAIN board. Also connect a 1 kΩ resistor to Pin 4 at the same
time. (Connection 1)
2. Check that no discs are loaded in the unit.
3. With the power OFF, press the 1/u button while pressing the
INPUT button, and turn on the power at the same time.
4. The rotary table will continue rotating in the clockwise direction.
5. Observe the waveform at that time on the oscilloscope.
6. Loosen the screw securing the D.SENS (LUMINOUS) board
slightly.
7. Slide the D.SENS (LUMINOUS) board to the left and right so
that the peak of the D0 waveform is at the center between the
descending point of the T1 waveform and ascending point of the
T2 waveform. (Waveform 1) After adjusting, apply locking
compound.

8. Disconnect the resistor connected to Pin 4 of CN506 of the
MAIN board. (Connection 2)
9. Observe the waveform on the oscilloscope. (Waveform 2)
10. Adjust RV501 of the MAIN board so that the waveform on the
oscilloscope satisfies the following adjustment value 1.
11. Press the 1/u button and turn OFF the power.
12. Press the 1/u button, turn on the power, press the OPEN/
CLOSE button, and open the front cover . Next rotate the DISC/
CHARACTER dial in the counterclockwise direction
continuously so that the rotary table rotates continuously in the
counterclockwise direction.
13. Observe the waveform on the oscilloscope and confirm that it
satisfies the adjustment value 2 (waveform 3). If it does not,
adjust RV501 of the MAIN board.

14. After the adjustment, load a disc only in slit 1, and press the 1/
u button to turn off the power.
15. Press the 1/u button while pressing the PUSH ENTER button
to turn on the power.
16. If the rotary table makes one round, and “YES” is displayed on
the fluorescent indicator tube after it stops, it means that the
adjustment has been performed properly.
Adjustment value 1:
At the shoulder part of waveform D1, T1 becomes H and T2 becomes L, and at the same time, the Y width must not be smaller
than 1/4 of the Z width.
In order to satisfy this value more easily, adjust so that X=Y approximately and observe the deviation of the waveform.
Adjustment value 2:
At the shoulder part of waveform D1, T1 becomes L and T2 becomes H, and at the same time, the Y width must not be smaller
than 1/4 of the Z width.
