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 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. 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
VOM or battery-operated AC 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)

SERVICING NOTES

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.

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 viscou-s (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.

* Replacement of USB board IC8 and BT board IC905

used in this set requires a special tool.

• The voltage and wav eform of CSP (chip size package) cannot

be measured, because its lead layout is different from that of
conventional IC.

• Lead layouts

surface

CAUTION

Use of controls or adjustments or performance of procedures
other than those specified herein may result in hazardous radiation
exposure.

This appliance is classified as a
CLASS 1 LASER product.
The CLASS 1 LASER PRODUCT
MARKING is located on the rear
exterior.

Laser component in this product is capable of emitting radiation
exceeding the limit for Class 1.

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.

ANTITHEFT LOCK MODE

This mode is used to unable to take sample disc out of disc table in
the shop.

Procedure:

1. Press the @/1 button to turn the power on.

2. Press the CD

3. Press two buttons of x CANCEL and Z for 5 seconds.

4. The message “CD LOCKED” is displayed on the fluorescent
indicator tube and the disc slot is locked. (Even if pressing
the Z button, the message “CD LOCKED” is displayed on
the fluorescent indicator tube and the disc table is locked.)

5. To release from this mode, press two buttons of x CANCEL and

Z for 5 seconds.

6. The message “CD UNLOCKED” is displayed on the fluores­cent indicator tube and the disc table is unlocked.

Note on USB board replacement

New part of EEP ROM (IC6) on the USB board cannot be used. Therefore,
if the mounted USB board (X-2149-040-1) is replaced, exchange new

EEP ROM (IC6) with that used before the replacement.

TEST MODE

HCD-U1BT

COLD RESET

The cold reset clears all data including preset data stored in the
RAM to initial conditions. Execute this mode when returning the
set to the customer.

Procedure:

1. Press two buttons of [DSGX] and @/1 simultaneously.

2. The fluorescent indicator tube becomes blank momentarily,
then becomes standby states.

COMMON TEST MODE

This mode is used to check operations of Amplifier.

Procedure:

1. Press the @/1 button to turn the power on.

2. Press two buttons of [DSGX] and [VOLUME +] for 5 seconds.

3. When the COMMON test mode is activated, the function
enters “AUDIO IN”, “c PLAY/SLEEP” blink on the fluo­rescent indicator tube.

4. Press the [ENTER] button, next mode is displayed on the
fluorescent indicator tube.

5. Press the [VOLUME +] button, “VOLUME MAX” is displayed
on the fluorescent indicator tube.

6. Press the [VOLUME --] button, “VOLUME MIN” is displayed
on the fluorescent indicator tube.

7. To release this mode, press the @/1 button.

PANEL TEST MODE

This mode is used to check the fluorescent indicator tube, LED,
model, destination, software version and button.

Procedure:

1. Press the @/1 button to turn the power on.

2. Press three buttons of [SEARCH], Z and @/1 simultaneously.

3. Fluorescent indicator tube and each LED is all turned on.

4. When the [DSGX] button is pressed, the screen is switched to

ELECTRICAL ADJUSTMENTS

CD SECTION

Note:

1. CD Block is basically constructed to operate without adjustment.

2. Use YEDS-18 disc (3-702-101-01) unless otherwise indicated.

3. Use an oscilloscope with more than 10 MΩ impedance.

4. Clean the object lens by an applicator with neutral detergent when the
signal level is low than specified value with the following checks.

5. Check the focus bias check when optical pick-up block is replaced.

Procedure :

1. Connect oscilloscope to TP (RFACI) and TP (VC) on the
BD83S board.

2. Press the ?/1 button to turn the power ON, and press
the Z (CD) button to open the CD disc tray.

3. Set disc (YEDS-18) on the tray and press the CD u button
to playback.

4. Confirm that oscilloscope waveform is as sho wn in the f igure
below. (eye pattern)
A good eye pattern means that the diamond shape (◊) in the
center of the waveform can be clearly distinguished.
