Laser component in this product is capable of emitting radiation
exceeding the limit for Class 1.
This appliance is classified as
a CLASS 1 LASER product.
The CLASS 1 LASER PRODUCT 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. 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 V OM
or battery-operated A C v oltmeter. 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
repain 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.

Procedure:
While pressing the CLEAR button with the power OFF, press the
1/u button and turn on the power.
The fluorescent display tube displays “ ALL ERASE” and all memories will be cleared.
AGING MODE
• 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 convenient func-
tions
• 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.

Aging Procedure
1. Turn ON the power of the unit. Pr ess the § OPEN/CLOSE and
open the front cover.
2. Change the COMMAND MODE switch (S901) on set to CD1 .
3. Press the AGING STAR T button of the remote commander for
aging mode (J-2501-123-A).
4. When the disc set mode is set, the · and P LEDs blink.
5. Rotate the DISC/CHARACTER dial. The slits (No. 60, 120,
180, 240, 300) for setting the discs will come forward. Insert the
discs into these slits. Do not set the discs in other slits.
6. Set whether the self-protection function during errors is equipped
with the unit. Press the REPEAT button. If “REPEAT” is displayed on the Fluorescent indicator tube, it means the function
is provided. If “REPEA T” is not displayed, it means the function
is not provided.

8. The · LED blinks, the aging mode is set, and aging is started.
9. The aging cycle lasts 3 minutes. If errors occur during aging, the
error number will be displayed on the Fluorescent indicator tube.
(Refer to the following table for the details of the errors.)
10. Aging will be repeated as long as no errors occur.
11. After each aging cycle, the number displayed on the Fluorescent
indicator tube will increase.
12. To end aging, disconnect the power cord from the outlet.

The error codes displayed during operations and when errors occur
are the same as the “AGING MODE” described earlier.
TABLE AGING MODE
• This mode is used for rotating the table randomly.
• Aging will be performed continuously unless an error occurs.
• When an error occurs, the error code will be displayed on the
fluorescent indicator tube.
Procedure:
1. Set discs in slits 1, 2, 99, 100, and 200.
2. With the power ON, while pressing the GROUP 3 button and
§ OPEN/CLOSE button, press the +100 button.
3. When the mode is set, both the · and P indicators will
start to blink.

blink and aging starts.
5. To end the mode, press the 1/u button or disconnect the power
cord from the outlet.
During aging, operations will be carried out sequentially in the order of No. 1, No. 2, No. 100, No. 99, and No. 200 slits.
The error codes displayed during operations and when errors occur
are the same as the “AGING MODE” described earlier.

TEST MODE
5-1. ADJ MODE
1. Turn ON the power of the unit, set disc to disc table, and perform chucking.
2. Disconnect the power supply plug from the outlet.
3. To set ADJ mode, connect the test point (ADJ) of the MAIN
board to Ground, and connect the power supply plug to the outlet.
In this mode, table rotation and loading operations are not performed
because it is taken that the disc has already been chucked.
Note: The same operations are also performed in the follo wing when
the test point (ADJ) is connected to Ground after turning on
the power.
• Direct search (movement of sledding motor) is not performed dur-

• Ignored even when GFS becomes L
• Ignored even when the Q data cannot be read

Note:
1. CD Block is basically designed to operate without adjustment.
Therefore, check each item in order given.
2. Use YEDS-18 disc (3-702-101-01) unless otherwise indicated.
3. Use an oscilloscope with more than 10MΩ impedance.
4. Clean the object lens by an applicator with neutral detergent when
the signal level is low than specified value with the following
checks.
Note: A clear RF signal wa veform means that the shape “◊” can be
clearly distinguished at the center of the waveform.
