HCD-WZ5

Laser component in this product is capable

of emitting radiation exceeding the limit for

Class 1.

CAUTION

Use of controls or adjustments or performance of procedures

other than those specified herein may result in hazardous radiation

exposure.

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 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.

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 pick-

up block. Therefore, when checking the laser diode emission,

observe from more than 30 cm away from the objective lens.

NOTES ON HANDLING THE OPTICAL PICK-UP

BLOCK OR BASE UNIT

This appliance is

classified as a CLASS 1

LASER product. This

label is located on the

rear exterior.

The following caution label is located inside the apparatus.

SAFETY-RELATED COMPONENT WARNING!!

COMPONENTS IDENTIFIED BY MARK 0OR DOTTED LINEWITH

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 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.

[When bringing in the equipment for service]

In case of repairing, please bring the entire system set([HCD-WZ5,

DXA-WZ5],except for the speaker) to the service station.

SECTION 3

ELECTRICAL ADJUSTMENTS

CD SECTION

Note:

1. CD Block is basically constructed to operate without

adjustment.

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

3. Use an oscilloscope with more than 10 MΩimpedance.

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 block is replaced.

Focus Bias Check

Procedure :

1. Connect an oscilloscope to TP5 (RF AC) and TP7 (DVC) on

the CD board.

2. Press the ?/1 button to turn the power on, and press the Z

button to open the CD disc tray.

3. Put the test disc (YEDS-18) in and press the gG button to

play-back.

4. Confirm that the oscilloscope waveform is as shown in the figure

below. (eye pattern)

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

center of the waveform can be clearly distinguished.

[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, EQ EDIT and ?/1simultaneously.

2. The liquid crystal display does not display any message and the

set is reset.

[MD/VIDEO Function Selection Mode]

•This mode is used to select the function of MD or VIDEO.

Procedure:

1. Press the ?/1button to turn the set on.

2. Press the MD(VIDEO) and ?/1buttons simultaneously.

3. The function will change from MD to VIDEO, and "VIDEO" is

displayed.

4. To change change back to MD , repeat the same procedure.

[AM Channel Step 9 kHz/10kHz Selection Mode]

•Either the 9 kHz step or 10 kHz step can be selected for the AM

channel step.

Procedure:

1. Set the function to AM.

2. Turn off the main power.

3. While depressing the xbutton, press the ?/1button to turn

on the main power.

4. The channel step is changed over.

* For E model only

[CD Ship Mode (without Cold Reset)]

•This mode moves the optical pick-up to the position durable to

vibration. Use this mode when returning the set to the customer

after repair.

Procedure:

1. Press the ?/1button to turn the set on.

2. Set the function to CD.

3. Press the xbutton and the M(Control lever) button

simultaneously.

4. After the "STANDBY" display blinks six times, the message

"LOCK" is displayed on the liquid crystal display, and the CD

ship mode is set.

[CD Ship Mode (without Cold Reset)]

•This mode is used to perform the CD Ship Mode with Cold Reset.

Procedure:

1. Press the ?/1button to turn the set on.

2. Set the function to CD.

3. Press three buttons x, zSTART (REC PAUSE) and

.m – simultaneously.

4. After the "STANDBY" display blinks six times, the message

"LOCK" is displayed on the liquid crystal display, and the CD

ship mode is set.

[Disc Tray Lock]

•The disc tray lock function for the antitheft of an demonstration

disc in the store is equipped.

Setting Procedure :

1. Press the ?/1button to turn the set on.

2. Set the function to CD.

3. Press two buttons of x and Z simultaneously for five seconds.

4. The message “LOCKED” is displayed and the tray is locked.

Releasing Procedure :

1. Press two buttons of xand Zsimultaneously for five seconds

again.

2. The message “UNLOCKED” is displayed and the tray is

unlocked.

Note :When “LOCKED” is displayed, the tray lock is not released

by turning power on/off with the ?/1button.

[GC Test Mode]

•This mode is used to check the software version, key board,VACS

level, liquid crystal display and LEDs.

Procedure:

1. Press three buttons x, zSTART (REC PAUSE) and

TUNER/BAND simultaneously.

2. Segments of the liquid crystal display and LEDs are all turned

on.

3. To enter the software version display mode, press the .m –

button. The model name and destination are displayed.

4. Each time the .m – button is pressed, the display changes

in the following order. MC, GC, CD, CDD, CDMA, CDMB,

BDA, BDB, ST,TA, TM, TC and MD. Each time the + M >

button is pressed, the contents of the version display change.
