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
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. Follo w 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 lowvoltage 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 A C range are suitable. (See Fig. A)

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
pick-up block. Therefore, when checking the laser diode emission, observe from more than 30 cm away from the objective lens.
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 repeatedly.

CD-TEXT TEST DISC
This unit is able to display the test data (character information) written in the CD on its fluorescent indicator tube.
The CD-TEXT TEST DISC (TGCS-313:4-989-366-01) is used for checking the display.
To check, perform the following procedure.
Checking Method:
1. Turn ON the power, set the disc on the disc table with the side labeled as “test disc” as the right side, close the front co v er, and chuck the
disc.
2. Press the · button and play back the disc.
3. The following will be displayed on the fluorescent indicator tube.
Display : 1kHz/0 dB/ L&R
4. Press the ≠ 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 “Table 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 displayed as a space or a character resembling it. For
details, refer to “Table 2 : CD-TEXT DISC Recorded Contents and Display”.

• 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 oper ations. However, the stopping conditions differ 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.

Function which voluntarily corrects errors which occur during normal operations by retries.
If this function is not provided, all operations will be stopped

If this function is provided, and errors can be corrected by
retries, aging will be continued without stopping.

Aging procedure:
Some operating method will be changed depending on if the following jig for the aging mode exists or not.
1. Turn ON the power of the unit. Open the front cover.
2. Press the [AGINGSTART] button of the remote commander for
aging mode.
3. When the disc set mode is set, the · and P LEDs blink.
4. Rotate the JOG dial. The slits (No. 10, 20, 30, 40, 51) for setting
the discs will come forward. Insert the discs into these slits. Do
not set the discs in other slits.
5. Set the use/disuse of the self protection function in errors. Press
the
[REPEAT] button. When REPEAT is displayed on the fluo-
rescent indicator tube, the self protection function during the
error will become “Use”.
If the REPEAT display is OFF, it means that the function is not
used. (Normally set to “Use” when performing aging.)
6. Press the · button.
7. The · LED blinks, the aging mode is set, and aging is started.
8. The aging cycle lasts 3 minutes. When problems occur during
aging, the error number will be displayed on the fluorescent indicator tube, and the P LED will light up.
(Refer to the following table for the details of the errors.)
9. Aging will be repeated as long as no errors occur.
10. After each aging cycle, the number displayed on the Fluores-
cent indicator tube will increase.

Confirm the following :
A/B x 100 = less than ± 10%
11. Turn OFF the power, and remove the lead wire connected at
step 7.
Note : • Try to measure several times to make sure than the ratio of A
