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)

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.

CAUTION

Use of controls or adjustments or performance of procedures
other than those specifi ed herein may result in hazardous radia-
tion exposure.

SECTION 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 fl exible 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 refl ective 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.

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 fl ow)

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.

CHECKING THE OPERATION AFTER REPAIR

After repair completion, connect the “iPod” etc. corresponding to
this unit, and check the operation of playback (HCD-SBT300W/
SBT300WB only), charge, etc.

NOTE OF PERFORMING THE OPERATION CHECK IN
THE STATE THAT HEAT SINK WAS REMOVED

When performing the operation check in the state that this unit was
disassembled, it is possible to perform the operation check in the
state that heat sink was removed. But perform the operation check
in the volume state as low as possible.

TEST DISCS

Use following TEST DISC (for CD) when this unit confi rms the
operation and checks it.

(Even if pressing the [Z] button, the message “LOCKED”

is displayed on the liquid crystal display and the disc tray is
locked)

Releasing method:

1. Press two buttons of the [x] and [Z] simultaneously for fi ve
seconds.

2. The message “UNLOCKED” is displayed on the fl uorescent
indicator tube and the disc tray is unlocked.

AM STEP CHANGE
(Except AEP and UK models)

It can change AM step interval into 9 kHz or 10 kHz.

Procedure:

1. Press the [

CHECK VERSION DISPLAY

It can confi rm the MC, CD and NW version.

Procedure:

1. Press the [

] button to turn the power on.

2. Press two buttons of the [x] and [BASS BOOST] simultane­ously for three seconds.

3. It enters the check version display mode, the MC version is
displayed on the fl uorescent indicator tube.

4. Each time [> TUNE +] button is pressed, the display chang­es CD version → NW version (HCD-SBT300W/SBT300WB
only) this order, and release from check version display mode.

7. When pressing the [x] button while the each version is dis-

played, year, month and day of the software creation is dis­played. When pressing the [x] button again, the display re­turns to the each version display.

8. When pressing the [. TUNE −] button, “K 0 V0” is dis-

played on the fl uorescent indicator tube.

9. Each time a button is pressed, “K 0” value increases. However,
once a button is pressed, it is no longer taken into account.

When pressing the all buttons, display becomes “K10”.

10. “V0” value increases “V2”, “V4”, “V6” “V8”, “V0” if turn
the [VOLUME] knob clockwise, or it decreases “V8”, “V6”,
“V4”, “V2”, “V0” if turn the knob counterclockwise.

Releasing method:

Press two buttons of the [FUNCTION] and [. TUNE −] simul­taneously for three seconds.

signal

generator

unit

Procedure:

1. Press the [?/1] button to turn the power on.

2. Input the following signal from signal generator to FM antenna
input directly.

Carrier frequency : A = 87.5 MHz, B = 98 MHz, C = 108 MHz
Deviation : 75 kHz
Modulation : 1 kHz
ANT input : 35 dBu (EMF)

Note: Use 75 ohm coaxial cable to connect signal generator and the unit.

You cannot use video cable for checking.

Use signal generator whose output impedance is 75 ohm.

3. Press the [FUNCTION] button to turn the FM tuner function
and scan the input FM signal with automatic scanning.

4. Confi rm that input frequency of A, B and C detected and auto-
matic scanning stops.

When the station signal is received in good condition, automatic
scanning stops.

CD SECTION

Note:

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

2. Use HLX-A1 disc (Part No. J-2501-307-A) 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 specifi ed value with the following check.

3. Press the [FUNCTION] button to turn the CD function.

4. Press the [Z] button to open the disc tray and set the disc

5. Press the [Z] button to close the disc tray.

6. Press the [u] button to playback.

7. Confi rm that oscilloscope waveform is as shown in the fi gure

A good eye pattern means that the diamond shape (◊) in the

center of the waveform can be clearly distinguished.
