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 A C leaka ge from an y e xposed metal part to earth gr ound and
from all exposed metal parts to any exposed metal part having a
return to chassis, must not exceed 0.5 mA (500 microamperes.).
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 A C 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-63T rd are e xamples 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)

SERVICING NOTES
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 objecti ve lens.
CAUTION
Use of controls or adjustments or performance of procedures
other than those specified herein may result in hazardous radiation exposure.
LASER DIODE AND FOCUS SEARCH OPERATION
CHECK
This appliance is classified as a CLASS 1 LASER product.
The CLASS 1 LASER PRODUCT MARKING is located on
the rear exterior.
HOW T O OPEN THE DISC T ABLE WHEN PO WER
SWITCH TURNS OFF
Insert a tapering driver into the aperture of the unit bottom, and
turn it in the direction of the arrow (to OUT direction).
table
tapering driver
*To close the disc table, turn the tapering
driver in the reverse direction (to IN direction).
Carry out the “S curve check” in “CD section adjustment” and
check that the S curve waveforms is output three times.
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 the 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 CLEANING OF OPTICAL PICK-UP LENS
Do not clean up the optical pick-up lens.

Procedure:
1. Remove the discs from all trays.
2. While pressing the DISK SKIP button and PROGRAM button, press the POWER button to turn ON the power.
3. “NO DISC” is displayed, indicating that the mode has ended.
Note:“NO DISC” may be displayed even if there are discs on the
trays.
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-313:4-989-366-01) is used for checking the display.
To check, perform the following procedure.
Checking Method:
1. Set the test disc on a free tray, and chuck the disc.
2. Press the H button and playback the disc.
3. The following will be displayed on the fluorescent indicator tube.
Display : 1kHz/0 dB/ L&R
4. Turn the l AMS L knob 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

This set has the Aging mode for operation check of the mechanism deck.
• If a failure occurred
The aging operation stops and a faulty status is displayed on the fluorescent indicator tube.
• If no failure occurs
The aging operation continues repeatedly.
Note: Do not use the test disc when performing aging.
Aging will not be performed properly if discs with tracks shorter than 4 seconds are used.
Procedure:
1. Press the [POWER] button and turn ON the power.
2. Set discs on all trays.
