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 have an accurate low-voltage
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.

PLA Y MODE/TUNING MODE
button to set the “ALL DISCS” mode, and the PRESET EQ
button to “REPEAT” off.
2) Load the tapes recording use into both decks.
3) Press three buttons x , PLAY MODE/TUNING MODE ,
and EX-CHANGE simultaneously.
4) Aging operations of CD and tape are started at the same time.
5) To exit the aging mode, perform [Cold Reset].
2.Aging mode in CD section
1) Operation during aging mode
• In the agining mode ,the program is excuted in the following
sequence.
(1) The disc tray opens and closes.
(2) The disc tray turns to select a disc 3.
(3) The pick-up accesses to the first track, and plays 3 seconds.
(4) The pick-up accesses to the last track, and plays 3 seconds.
(5) The disc tray opens and closes.
(6) The disc tray turns to select a disc 1.
(7) The same operation starts like step (3).
(8) After a disc 1 aging operation, a disc 2 is selected.
(9) When an aging operation of a disc 3 is completed, the display
“AGING ∗∗∗∗” value increases.
(10) If no error occurs, the aging operation continues repeatedly.

TEST MODE
HCD-GX450
[Change-over of AM Tuner Step between 9 kHz and
10 kHz]
•A step of AM channels can be changed ov er between 9 kHz and
10 kHz.
Procedure:
1. Press ?/1 button to turn the set ON.
2. Select the function “TUNER”, and press TUNER/BAND
button to select the BAND “AM”.
3. Press ?/1 button to turn the set OFF.
4. Press PLAY MODE/TUNING MODE and ?/1 buttons si-
multaneously, and the display of fluorescent indicator tube
changes to “AM 9 k STEP” or “AM 10 k STEP”, and thus the
channel step is changed over.
[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 three buttons x , PLAY MODE/TUNING MODE ,
and DISC 1 simultaneously.
2. The fluorescent indicator tube displays “COLD RESET” and
the set is reset.
[Aging Mode]
This mode can be used for operation check of CD section and tape
deck section.
• If an error occurred:
The aging operation stops and is displayed status.
• If no error occurs:
The aging operation continues repeatedly.
1.Operating method of Aging Mode
Press ?/1 button to turn the set ON and select “CD” of the function.
1) Set three discs in tray. Press the
PLA Y MODE/TUNING MODE
button to set the “ALL DISCS” mode, and the PRESET EQ
button to “REPEAT” off.
2) Load the tapes recording use into both decks.
3) Press three buttons x , PLAY MODE/TUNING MODE ,
and EX-CHANGE simultaneously.
4) Aging operations of CD and tape are started at the same time.
5) To exit the aging mode, perform [Cold Reset].
2.Aging mode in CD section
1) Operation during aging mode
• In the agining mode ,the program is excuted in the following
sequence.
(1) The disc tray opens and closes.
(2) The disc tray turns to select a disc 3.
(3) The pick-up accesses to the first track, and plays 3 seconds.
(4) The pick-up accesses to the last track, and plays 3 seconds.
(5) The disc tray opens and closes.
(6) The disc tray turns to select a disc 1.
(7) The same operation starts like step (3).
(8) After a disc 1 aging operation, a disc 2 is selected.
(9) When an aging operation of a disc 3 is completed, the display
“AGING ∗∗∗∗” value increases.
(10) If no error occurs, the aging operation continues repeatedly.
2) Error display

ELECTRICAL ADJUSTMENTS
CD SECTION
Note:
1. CD Block is basically designed to operate without adjustment.
Therefore, check each item in order given.
2. Use YEDS-18 (3-702-101-01) unless otherwise indicated.
3. Use an oscilloscope with more than 10MΩ impedance.
4. Clean the object lens by an applicator with neutral deter gent when the
signal level is low than specified value with the following checks.
S-CURVE CHECK
BD board (New type model)
BD81A board (Old type model)

Procedure:
1. Connect an oscilloscope to TP (FE) and TP (VC) on the BD
board (New type model) or BD81A board (Old type model).
2. Press the I/1 button to turn the power on.
3. Load the disc (YEDS-18) and actuate the focus search. (In
consequence of open and close the disc tray, actuate the focus
search)
4. Confirm that the oscilloscope waveform (S-curve) is
symmetrical between A and B. And confirm peak to peak le vel
within 2 ± 1 Vp-p.
