CAUTIONUse of controls or adjustments or performance of procedures

radiation exposure.

HCD-GNZ55D

NOTES ON HANDLING THE OPTICAL PICK-UP BLOCKOR BASE UNIT

The laser diode in the optical pick-up block may suffer electrostaticbreakdown 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 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 270C 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 SOLDERBoards requiring use of unleaded solder are printed with the lead

free 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 alsobe added to ordinary solder.

This appliance is

claassified as a CLASS 1

LASER product. This

label is located on the

rear exterior.

NOTES ON LASER DIODE EMISSION CHECKThe laser beam on this model is concentrated so as to be focused on

the disc reflective surface by the objective lens in the optical pick-

up 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 forClass 1.

Ver. 1.1

NOTE ON REPLACEMENT OF DMB15 BOARDNew part of EEPROM (IC103) on the DMB15 board cannot be

used. Therefore, if the mounted DMB15 board (A-1167-778-A, etc.)is replaced, exchange new EEPROM (IC103) with that used before

the replacement.

HCD-GNZ55DSECTION 3TEST MODE

[PANEL TEST MODE] This mode is used to check the fluorescent indicator tube, LEDs,

keys, VOLUME jog, model, destination, software version and

VACS level.

Procedure:

1. Press x button, [ILLUMINATION]button and [DISC2]button

simultaneously.2. All LEDs and segments in fluorescent indicator tube are lighted

up.

3. When you want to enter to the software version dispaly mode,

press [DISC1]button. The model information appears on the

fluorescent indicator tube. Press [DISC1]button again to view

the destination information.

4. Each time [DISC1]button is pressed, the display changes from

MC version, SYS version, UI version, DVD version, CDMA

version, CDMB version, ST version, TA version, TM version,

TC version in this order, and returns to the model version display.

5. When [DISC3]button is pressed while the version numbers are

being displayed except model and destination, the date of the

software creation appears. When [DISC3]button is pressed

again, the display returns to the software version display. When

[DISC1]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 [DISC2]button, the key check mode is activated.

7. In the key check mode, the fluorescent indicator tube displays

K 0 V0.

Turn the [OPERATIONALDIAL]clockwise; K value increases

by one. Turn the [OPERATIONALDIAL]counterclockwise; K

value increases by one. Each time a button is pressed, K value

increases. Press other keys on main unit to check whether the

key is detected. 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 [DISC3]button is pressed after all LEDs and segments in

fluorescent indicator tube light up, the fluorescent indicator tube

displays VACS A. A is VACS level which is triggered by signal

level.

9. When [DISCSKIP/EX-CHANGE]button is pressed after all LEDs

and segments in fluorescent indicator tube light up, alternate

segments in fluorescent indicator tube would light up. If you

press [DISCSKIP/EX-CHANGE]button again, another half of

alternate segments in fluorescent indicator tube would light up.

button or [DISCSKIP/EX-CHANGE]button is pressed. The

message LOCKED will appears on the fluorescent indicator

tube.

Procedure:


2. Select DVD function.3. Press xbutton and [OPEN/CLOSE]button simultaneously and

hold down until LOCKED or UNLOCKED appears on the

fluorescent indicator tube (around 5 seconds).

[TCM OFFLINE MODE] This mode prevents the system from turning off automatically

when TCM is not connected. Therefore, measurements can be

done even when TCM is not connected during production.

Procedure:

UNLEADED SOLDER

Boards requiring use of unleaded solder are printed with the lead

free 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.

New part of EEPROM (IC103) on the DMB15 board cannot be used.

Therefore, if the mounted DMB15 board (A-1167-778-A, etc.) is replaced,

exchange new EEPROM (IC103) with that used before the replacement.
