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.

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
claassified as a CLASS 1
LASER product. This
label 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 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.

TEST MODE

[PANEL TEST MODE]

•This mode is used to check the LCD display, LEDs, keys,
VOLUME jog and OPERATION DIAL jog, model,
destination, software version and VACS level.

Procedure:

1. Press x button, [DISPLAY] button and X button simultaneously .

2. All LEDs and segments in LCD display are lighted up. All
LEDs are lighted up in red.

3. When you want to enter to the software version dispaly mode,
press [FUNCTION] button. The model inf ormation appears on
the fluorescent indicator tube. “GRL2D” is shown for HCD­GNZ333D and “GRL4D” is shown for HCD-GNZ444D. Press
[DISC 1] button again to view the destination information.

4. Each time [DISC 1] button is pressed , the display changes from
MC version, SYS version, UI version, D VD version, CDMA
version, CDMB version, ST version, T A version, TM v ersion,
TC version in this order, and returns to the model information
display.

5. When [DISC 3] button is pressed while the version numbers
are being displayed except model and destination, the date of
the software creation appears. When [DISC 3] button is pressed
again, the display returns to the software version display . When
[DISC 1] button is pressed while the date of the software creation
is being displayed, the date of the software creation is displayed
in the same order of software version display.

6. Press [DISC 2] button, the key check mode is activated.

7. In the key check mode, the LCD displays “K 0 V0 J0”.
Each time a button is pressed, “K” value increases. However,
once a button has been pressed, it is no longer taken into
account.
“V” value increases in the manner of 0, 1, 2, 3 ... if [VOLUME]
knob is turned clockwise, or it decreases in the manner of 0,
9, 8, 7 ... if [VOLUME] knob is turned counterclockwise.

8. When [DISC SKIP/EX-CHANGE] button is pressed after all LEDs
and segments in LCD display light up, alternate segments in
LCD display would light up. If you press [DISC SKIP/EX-
CHANGE] button again, another half of alternate segments in
LCD display would light up. When [DISC SKIP/EX-CHANGE]
button is pressed again, all segments lights off. Press [DISC
SKIP/EX-CHANGE] button again would cause all segments
lights up.

9. To release from this mode, disconnect the AC plug.

[DVD SHIP MODE]

•This mode can run the DVD sled motor optionally. Use this
mode, for instance, when cleaning the optical pick-up.

Procedure:

1. Press the

2. Press the [FUNCTION] button to select DVD function.

3. Press two buttons of DVD N and @/1 simultaneously.

4. Set to the DVD ship mode. (chucking on)

5. After blink “STANDBY”, “LOCK” is displayed, disconnect
the AC plug.

[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 @/1 button to turn on the system.

2. Press x button, [TUNER/BAND] button, and @/1 STANDBY
button simultaneously.

3. The message “RESET” appears on the LCD display. Then,
the LCD display becomes blank for a while, and the system is
reset.

[TUNER STEP CHANGE]

•The step interval of AM channels can be toggled between 9
kHz and 10 kHz. This mode is not available for Saudi Arabia
and Russia models.

Procedure:

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

2. Press [TUNER/BAND] button repeatedly to select the “AM”.

3. Press

4. After pressing the [DISPLAY] button, press [PRESET +] button
and @/1 STANDBY button simultaneously. The system will
turn on automatically. The message “AM 9K STEP” or “AM
10K STEP” appears on the LCD display and thus the channel
step is changed.
