CAUTION
Use of controls or adjustments or performance of
procedures other than those specified herein may
result in hazardous radiation exposure.
Notes on chip component replacement
• Never reuse a disconnected chip component.
• Notice that the minus side of a tantalum capacitor may be dam-
aged by heat.
Flexible Circuit Board Repairing
• K eep 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.
This appliance is classified as a CLASS 1 LASER product.
The CLASS 1 LASER PRODUCT MARKING is located on
the rear exterior.
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 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 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 2 V AC range are suitable. (See Fig. A)

exceeding the limit for Class 1.

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 objectiv e lens.

instance, when cleaning the pickup.
Procedure:
1. Select the function “CD”.
2. Press three buttons GROOVE , ENTER/NEXT , and
FLASH simultaneously.
3. The Sled Servo mode is selected, if “CD” is blanking on the
fluorescent indicator tube.
4. With the CD in stop status, press ) button in CD section
to move the pickup to outside track, or 0 button to inside
track.
5. To exit from this mode, perform as follows:
1) Move the pickup to the most inside track.
2) Press three buttons in the same manner as step 2.
Note:
• Always move the pickup to most inside track when exiting from
this mode. Otherwise, a disc will not be unloaded.
• Do not run the sled motor excessively, otherwise the gear can
be chipped.
[Change-over of AM T uner Step between 9kHz and 10kHz]
• A step of AM channels can be changed over between 9kHz and
10kHz.
Procedure:
1. Press POWER button to turn the set ON.
2. Select the function “TUNER”, and press TUNER/BAND
button to select the BAND “AM”.
3. Press POWER button to turn the set OFF.
4. Press ENTER/NEXT and POWER buttons simultaneously,
and the display of fluorescent indicator tube changes to “AM
9k STEP” or “AM 10k STEP”, and thus the channel step is
changed over.
[LED and Fluorescent Indicator Tube All Lit, Key Check
Mode]
Procedure:
1. Press three buttons GROO VE , ENTER/NEXT , and DISC 3
simultaneously.
2. LEDs and fluorescent indicator tube are all turned on.
Press DISC 2 button, and the key check mode is activated.
3. In the key check mode, the fluorescent indicator tube displays
“K 1 V0 J0”. Each time a button is pressed, “K”value increases. However , once a button is pressed, it is no longer taken
into account.
“J” Value increases like 1, 2, 3 ... if rotating JOG knob in “+”
direction, or it decreases like 0, 9, 8 ... if rotating in “–” direction.
“V” Value increases like 1, 2, 3 ... if rotating VOLUME knob
in “+” direction, or it decreases like 0, 9, 8 ... if rotating in “–
” direction.
4. To exit from this mode, press three buttons in the same manner as step 1, or disconnect the power cord.
[Change-over of FUNCTION Name]
• The FUNCTION name of external input terminal can be changed
over to VIDEO or MD. W ith the FUNCTION selected to “MD”,
about 5dB mute is applied to the input gain.
Procedure:
1. Press POWER button to turn the set OFF.
2. Press POWER button together with FUNCTION button, and
the power is turned on, the display of fluorescent indicator
tube changes to “MD” or “VIDEO” instantaneously, and thus
the FUNCTION is changed over.
