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 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 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 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 v oltmeter. The “limit” indication
is 0.75 V, so analog meters must hav e an accurate lo w-v oltage
scale. The Simpson 250 and Sanwa SH-63Trd are e xamples of
a passive VOM that is suitable. Nearly all battery operated
digital multimeters that have a 2V AC range are suitable. (See
Fig. A)

The release method of a CD disc tray LOCK function

There is a disc lock function for the disc theft prevention for a
demonstration at a shop front in this machine.
Procedue:

1. Press the ?/1 button to turn the set on.

2. Press two buttons of x and Z (EJECT) simultaneously for
five seconds.

3. The message “LOCKED” is displayed and the tray is locked.
(Even if exiting from this mode, the tray is still locked.)

4. Press two buttons of x and Z (EJECT) simultaneously for
five seconds again.

5. The message “UNLOCKED” is displayed and the tray is
unlocked.

6. To exit from this mode, press the ?/1 button to turn the set
off.

Unleaded solder

Boards requiring use of unleaded solder are printed with the lead­free mark (LF) indicating the solder contains no lead.
(Caution: Some printed circuit boards may not come printed with
the lead free mark due to their particular size.)

: LEAD FREE MARK

Unleaded solder has the following characteristics.

• Unleaded solder melts at a temperature about 40°C higher than
ordinary solder.
Ordinary soldering irons can be used but the iron tip has to be
applied to the solder joint for a slightly longer time.
Soldering irons using a temperature regulator should be set to
about 350°C.
Caution: The printed pattern (copper foil) may peel away if the
heated tip is applied for too long, so be careful!

• Strong viscosity
Unleaded solder is more viscous (sticky , less prone to flow) than
ordinary solder so use caution not to let solder bridges occur such
as on IC pins, etc.

• Usable with ordinary solder
It is best to use only unleaded solder but unleaded solder may
also be added to ordinary solder.

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 pick­up block. Therefore, when checking the laser diode emission,
observe from more than 30 cm away from the objective lens.

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.

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
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.

or B : A is more than 10 : 7.

• Take sweep time as long as possible and light up the brightness
to obtain best waveform.

Procedure:

1. Connect an oscilloscope to TP (RFACO) and TP (VC) on the
BD81A board.

2. Press the I/1 button to turn the power on.

3. Load the disc (YEDS-18) and playback.

4. Confirm that oscilloscope waveform is clear and check if RF AC
signal level is correct or not.

Note: Clear RFAC signal w aveform means that the shape “ ◊ ” can be clearly

distinguished at the center of the waveform.

THIS NOTE IS COMMON FOR PRINTED WIRING BOARDS AND SCHEMATIC DIAGRAMS.
(In addition to this, the necessary note is printed in each block.)

For Schematic Diagrams.
Note:

• All capacitors are in µF unless otherwise noted. (p: pF)
50 WV or less are not indicated except f or electrolytics and

tantalums.

• All resistors are in Ω and 1/

specified.

• f : internal component.

• C : panel designation.

Note:

The components identi­fied by mark 0 or dot­ted line with mark 0 are
critical for safety.
Replace only with part
number specified.

• A : B+ Line.

• B : B– Line.

• H : adjustment for repair.

•Voltages and waveforms are dc with respect to ground un-

der no-signal (detuned) conditions.

•Voltages are taken with VOM (Input impedance 10 MΩ).

Voltage v ariations ma y be noted due to normal production
tolerances.
