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.

CAUTION

Use of controls or adjustments or performance of procedures
other than those specified herein may result in hazardous radiation
exposure.

SERVICING NOTES

HCD-NEZ31

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.

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.

LASER DIODE AND FOCUS SEARCH OPERATION
CHECK

During normal operation of the equipment, emission of the laser
diode is prohibited unless the upper lid is closed while turning ON
the S820. (push switch type)
The following checking method for the laser diode is operable.

• Method

Emission of the laser diode is visually checked.

1. Open the upper lid.

2. Push the S820 as shown in Fig.1.

Note: Do not push the detection lever strongly, or it may be bent or damaged.

3. Press the u button.

4. Check the object lens for confirming normal emission of the
laser diode. If not emitting, there is a trouble in the automatic
power control circuit or the optical pick-up.
In this operation, the object lens will move up and down 2
times along with inward motion for the focus search.

Basic Operations

Before using the system

To use the remote

Slide and remove the battery compartment lid , and
insert the two supplied R6 (size AA) batteries,
first, matching the polarities shown below.

Notes on using the remote

• With normal use, the batteries should last for about six months.

• Do not mix an old battery with a new one or mix different types of
batteries.

• If you do not use the remote for a long period of time, remove the
batteries to avoid damage from battery leakage and corrosion.

“

* When playing a CD-DA disc, (SHUF) Play performs the same

operation as normal (SHUF) Play.

Notes on Repeat Play

• All tracks or files on a disc are played repeatedly up to five times.

• “REPEAT 1” indicates that a single track or file is repeated until you
stop it.

Notes on playing MP3 discs

• Do not save other types of files or unnecessary folders on a disc that
has MP3 files.

• Folders that have no MP3 files are skipped.

• MP3 files are played back in the order that they are recorded onto
the disc.

• The system can only play MP3 files that have a file extension of
“.MP3.”

• If there are files on the disc that have the “.MP3” file extension,
but that are not MP3 files, the unit may produce noise or may
malfunction.

• The maximum number of:
– folders is 150 (including the root folder).
– MP3 files is 255.
–
– folder levels (the tree structure of files) is 8.

• Compatibility with all MP3 encoding/writing software, recording
device, and recording media cannot be guaranteed. Incompatible
MP3 discs may produce noise or interrupted audio or may not play
at all.

Notes on playing multisession discs

• If the disc begins with a CD-DA (or MP3) session, it is recognized
as a CD-DA (or MP3) disc, and playback continues until another
session is encountered.

• A disc with a mixed CD format is recognized as a CD-DA (audio)
disc.

CD ERROR HISTORY

When this mode is entered, optical pick-up error code is displayed
with the 8-character format on the fluorescent indicator tube.

Procedure:

1. Set the FUNCTION to CD.

2. While pressing the [DSGX] button, press the CD u button

and turn the [VOLUME] knob in the counter-clock wise.

3. CD error history is displayed on the liquid crystal display.

The first digit from the left indicates:

The first digit from the left indicates which mode the error history
is. In the optical pick-up error code mode, “D” is displayed on the
liquid crystal display.

The second digit from the left indicates:
(Error history No. display)

The second digit from the left indicates which order the error history
is. “1” indicates the latest error history, and each time the number
increases by one, the error history goes back to one-previous error.

The third and 4th digit from the left indicates:
(Error status display)

The third and 4th digit from the left indicates which error status is
indicated.

Display Status

01 Not focused (TOC read without a disc)

02 GFS NG (TOC read with a disc chucked)

03 Start operation time-over

04 Defocused continuously (Defocused during TOC reading)

05 Q code not entered for specified time

06 Tracking not turned ON

07 Blank disc (Blank disc TOC read)

distination
(In this case, North American model)

model name
(In this case, HCD-NEZXX)

5. Press the [PLAY MODE/TUNING MODE] button, “KEY 0 0” is

displayed on the liquid crystal display, and key test mode in.
Each time a key is pressed, the numerical value corresponding
to each key is displayed on the liquid crystal display.

6. To exit from this mode, perform the “COLD RESET”.

TUNER STEP CHANGE-OVER

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

Procedure:

1. Set the FUNCTION to AM, and press the

I/1 button to turn

the power off.

2. While depressing the [TUNER/BAND] button, press the I/1 button.

3. The message “9K STEP” or “10K STEP” is displayed on the
liquid crystal display, and thus the channel step is changed
over.

The 5th and 6th digit from the left indicates:

The 5th and 6th digit from the left indicates which processing when
a trouble occurred

MECHANICAL ADJUSTMENTS

CD POWER MANEGE

This mode is for switch the CD power supply on/off. Even if this
state pulls out AC plug, it is held.

Procedure:

1. Press the I/1 button to turn the power on.

2. Set the FUNCTION to CD.

3. Press the I/1 button again to turn the power off (standby).

4. While pressing the CD u button, press the I/1 button.

5. If turns power on and display “CD POWER”, then display
“ON” or “OFF”.

PRECAUTION

1. Clean the following parts with a denatured-alcohol-moistened
swab :

record/playback head pinch roller
erase head rubber belts
capstan idlers

2. Demagnetize the record/playback head with a head
demagnetizer. (Do not bring the head magnetizer close to the
erase head.)

3. Do not use a magnetized screwdriver for the adjustments.

4. After the adjustments, appiy suitable locking compound to
the parts adjusted.

5. The adjustments should be performed with the rated power
supply voltage unless otherwise noted.
