SAFETY CHECK-OUT (US Model)
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 0.5mA (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 instru-
ments.
to
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 volt-
meter. 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)

SAFETY-RELATED COMPONENT WARNING!!
COMPONENTS IDENTIFIED BY MARK A OR DOTTED

For the United Kingdom and
European countries
This Compact Disc player
is classified as a CLASS 1
CLASS 1 LASER PRODUCT LASER product.

KLASS 1 LASERAPPARAT The CLASS 1 LAS ER
PRODUCT label is located
on the rear exterior.
NOTES ON HANDLING THE OPTICAL PICK-UP
BLOCK OR BASE UNIT
The laser diode in the optical pick-up block may suffer
electrostatic breakdown because of the potential di-
ference 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 objec-
tive lens in the optical pick-up block. Therefore, when
checking the laser diode emission, observe from more
than 30cm away from the objective lens.

1-2. HOOKING UP THE SYSTEM
_DIGITAL OUT (OPTICAL) |
1
aD
14
You can connect the player with analog or
digital signat depending on your amplifier or
D/A converter.
Before hooking up the player:
* Turn off the power of each unit before
making connections.
* Connect the AC power cord last. For the
model supplied with the plug adaptor, use
it if the piug of the power cord does not
match your wall outfet.
* Be sure to insert the plugs firmly into the
jacks. Loose connection may cause hum
and noise.
* Leave a little slack in the connecting cord
to allow for inadvertent shock or vibration.
* Cord ptugs and jacks are color coded:
Red plugs and jacks are for the right
channel (R) and white ones for the left
channel (L).
Connecting Directly to an
Amplifier
Proceed as shown in Fig. EY.
a) Speaker system
b) Amplifier
c) Player
d) to a wall outlet
e) to an AC outlet
Note on LINE OUT
FIXED: The output levet is fixed.
VARIABLE: The output levet can be
adjusted with the LINE OUT/PHONE
LEVEL controt or LINE OUT LEVEL on the
remote commander.
* Connect your system to the VARIABLE
Output when using Level files.
* Note, if the LINE OUT/PHONE LEVEL
contro! or the LINE OUT LEVEL on the
romote commandor is turned while
recording, the recording level will change
even when it is preset on the tape deck,
Amplifler or D/A converter
When connecting to an amplifier or D/A
converter with OPTICAL IN, use DIGITAL
OUT (OPTICAL) instead of LINE OUT. See
the figures on the left.
1 Take off the cap.
2 Plug in firmly.
Note on DIGITAL OUT (OPTICAL)
When connecting with DIGITAL OUT
(OPTICAL), use the POC-15 audio optical
connecting cord (not supplied).
Please note that when the digital out is
connected, fade out, fade in, time fade and
level file functions cannot be used.

ELECTRICAL BLOCK CHECKING
Note:
1. CD Block basically constructed to operate without adjus-
tment. Therefore, check each item in order given.
2. Use YEDS-18 disc (3-702-101-01) unless otherwise indicat-
ed.
3. Use the oscilloscope with more than 10MQ impedance.
4. Clean an object lens by an applicator with neutral deter-
gent when the signal level is low than specified value
with the following checks.

Procedure :
1. Connect oscilloscope to test point TP (FE) on BD board.
2. Connect between test point TP (FEI) and TP (VC) with
lead wire.
3. Turned Power switch on and actuate the focus serch.
(actuate the focus serch when disc table is moving in and
out.)
4. Check the oscilloscope waveform (S curve) is symmetri-
cal between A and B. And confirm peak to peak level
within 3+1Vp-p.

within 3 +1Vpp
5. After check, remove the lead wire connected in step 2.
Note: @ Try to mesure several times to make sure that the
ratio of A: B or B: A is more than 10: 7.
e Take sweep time as long as possible and light up the
brightness to obtain best waveform.
