1) The pick-up should always be left in its conductive bag until immediately prior to use.
2) The pick-up should never be subjected to external pressure or impact.
2. Repair notes
1) The pick-up incorporates a strong magnet, and so should never be brought close to magnetic materials.
2) The pick-up should always be handled correctly and carefully, taking care to avoid external pressure and
impact. If it is subjected to strong pressure or impact, the result may be an operational malfunction
and/or damage to the printed-circuit board.
3) Each and every pick-up is already individually adjusted to a high degree of precision, and for that reason
the adjustment point and installation
screws should absolutely never be touched.
4) Laser beams may damage the eyes!
Absolutely never permit laser beams to enter the eyes!
Also NEVER switch ON the power to the laser output part (lens, etc.) of the pick-up if it is damaged.
5) Cleaning the lens surface
If there is dust on the lens surface, the dust should be cleaned away by using an air bush (such as used
for camera lens). The lens is held by a delicate spring. When cleaning the lens surface, therefore, a cotton swab should be used, taking care not to distort this.
6) Never attempt to disassemble the pick-up.
Spring by excess pressure. If the lens is extremely dirty, apply isopropyl alcohol to the cotton swab. (Do
not use any other liquid cleaners, because they will damage the lens.) Take care not to use too much of
this alcohol on the swab, and do not allow the alcohol to get inside the pick-up.
Storage in conductive bag
NEVER look directly at the laser beam, and don’t let contact
fingers or other exposed skin.

NOTES REGARDING COMPACT DISC PLAYER REPAIRS
1. Preparations
1) Compact disc players incorporate a great many ICs as well as the pick-up (laser diode). These components are sensitive to, and easily affected by, static electricity. If such static electricity is high voltage,
components can be damaged, and for that reason components should be handled with care.
2) The pick-up is composed of many optical components and other high-precision components. Care must
be taken, therefore, to avoid repair or storage where the temperature of humidity is high, where strong
magnetism is present, or where there is excessive dust.
2. Notes for repair
1) Before replacing a component part, first disconnect the power supply lead wire from the unit
2) All equipment, measuring instruments and tools must be grounded.
3) The workbench should be covered with a conductive sheet and grounded.
When removing the laser pick-up from its conductive bag, do not place the pick-up on the bag. (This is
because there is the possibility of damage by static electricity.)
4) To prevent AC leakage, the metal part of the soldering iron should be grounded.
5) Workers should be grounded by an armband (1MΩ)
6) Care should be taken not to permit the laser pick-up to come in contact with clothing, in order to prevent
static electricity changes in the clothing to escape from the armband.
7) The laser beam from the pick-up should NEVER be directly facing the eyes or bare skin.

ESD PRECAUTIONS
Electrostatically Sensitive Devices (ESD)
Some semiconductor (solid state) devices can be damaged easily by static electricity. Such components commonly are called Electrostatically Sensitive Devices (ESD). Examples of typical ESD devices are integrated circuits and some field-effect transistors and semiconductor chip components. The following techniques should
be used to help reduce the incidence of component damage caused by static electricity.
1. Immediately before handling any semiconductor component or semiconductor-equipped assembly, drain off
any electrostatic charge on your body by touching a known earth ground. Alternatively, obtain and wear a
commercially available discharging wrist strap device, which should be removed for potential shock reasons
prior to applying power to the unit under test.
2. After removing an electrical assembly equipped with ESD devices, place the assembly on a conductive surface such as aluminum foil, to prevent electrostatic charge buildup or exposure of the assembly.
3. Use only a grounded-tip soldering iron to solder or unsolder ESD devices.
4. Use only an anti-static solder removal device. Some solder removal devices not classified as "anti-static"
can generate electrical charges sufficient to damage ESD devices.
5. Do not use freon-propelled chemicals. These can generate electrical charges sufficient to damage ESD
devices.
6. Do not remove a replacement ESD device from its protective package until immediately before you are
ready to install it. (Most replacement ESD devices are packaged with leads electrically shorted together by
conductive foam, aluminum foil or comparable conductive materials).
7. Immediately before removing the protective material from the leads of a replacement ESD device, touch the
protective material to the chassis or circuit assembly into which the device will by installed.
CAUTION : BE SURE NO POWER IS APPLIED TO THE CHASSIS OR CIRCUIT, AND OBSERVE ALL
OTHER SAFETY PRECAUTIONS.
8. Minimize bodily motions when handing unpackaged replacement ESD devices. (Otherwise harmless motion
such as the brushing together of your clothes fabric or the lifting of your foot from a carpeted floor can generate static electricity sufficient to damage an ESD device).
Introduction
Thank you for choosing the
Harman Kardon DVD
The DVD is a multipurpose DVD player, capable of
playing both DVD-Audio and DVD-Video discs
and conventional CD audio discs with the highest
fidelity and access to future software upgrades
via the Internet. Along with conventional DVDAudio/Video and CD audio discs, the
DVD 31 is also compatible with MP3, CD-R and
CD-RW as well as VCD discs.
To enable you to get the maximum quality from
DVDs, the DVD is equipped with the latest in

Terminology
Terminology
Since they share some of the characteristics and
technology of CD players, many of the terms and
operational concepts used in a DVD player are
similar to what you may be familiar with from CD
players and changers, or older video disc formats
such as Laser Disc. However, if this is your first
DVD product, some of the terms used to describe
the features of a DVD player may be unfamiliar.
The following explanations should solve some of
the mysteries of DVD, and help you to enjoy all
the power and flexibility of the DVD format and
the DVD.
With the arrival of DVD, disc data capacity has
increased dramatically. On a DVD Video disc most
of this capacity is taken up by MPEG 2 video and
the multichannel movie soundtrack in Dolby
Digital and/or DTS.This information is compressed. But with DVD Audio, most of this
capacity is available for music only, without any
compression. This allows us to put the audio
information on the disc in the same quality as
the original mastering in the studio, in PCM up to
24 bit/192 kHz.
DVD-Audio's 24-bit system provides substantially
improved resolution of fine detail, because it
describes a specific point in the musical information using a 24-digit long string of one's and
zero's with 16,777,216 possible combinations,
while CD's primitive 16-bit system offers only
65,536 options.The 192 kHz frequency allows us
to have fast changes in music made audible,
which results in more dynamism, and also allows
us to obtain a higher bandwidth, up to 96 kHz.
Although that is far beyond the human audible
spectrum, it still improves the musical realism.
Aspect Ratio: This is a description of the width
of a video image in relation to its height. A conventional video screen is four units wide for every
three units of height, that’s why the ratio is
called ”4:3”. Newer wide aspect ratio video displays are 16 units wide for every nine units of
height, making them more like the screen in a
movie theater. The program material on a DVD
may be recorded in either format and, in addition, you may configure the DVD to play back in
either format, depending on the features recorded on a disc.
Title: For a DVD, a title is defined as an entire
movie or program.There can be as many chapters
within a title as the producers decide to include.
Most discs include only one title, but some may
have more than one, to give you a “Double
Feature” presentation.
Chapter: DVD programs are divided into chapters and titles. Chapters are the sub-sections programmed into a single title on a disc. Chapters
may be compared to the individual tracks on an
audio CD.
RGB Video: This is a new form of video signal
that eliminates many of the artifacts of traditional composite video signals by splitting the signal
into the three fundamental colors Red, Green
and Blue (RGB). With an RGB connection (via
SCART), you will see greater picture resolution
and eliminate many picture imperfections such as
the moiré patterns often seen on checkered patterned cloths. However, in order to benefit from
RGB video, you must have a video display with
an RGB compatible SCART input.
Progressive scan: DVD offers progressive scan
video outputs for use with compatible high-resolution televisions and projectors. Before DVD, no
consumer medium could store, transmit or display
video with full resolution. To conserve bandwidth,
analog compression (interlacing) is employed: first
the odd-numbered lines of a frame are displayed,
followed by the even-numbered lines.The result is
that only half of the video image is drawn at one
time; the viewer's brain must reassemble the
complete image.This is acceptable, if the monitor
is not too large and if there is not too much
motion in the image. Large displays and fast-moving images reveal the limitations of this system.
Thanks to DVD's immense data capacity, images
are now stored intact (progressively), so that all
the lines in each frame (odd and even) are shown
at the same time. But because most TV's cannot
handle a progressive signal, all current DVD players generate an interlaced output for compatibility. Now, the Harman Kardon DVD is among the
select few DVD players with true progressive scan
video output (NTSC and PAL) for use with compatible TV's and CRT projectors and with all plasma, LCD and DLP display devices via the component video output. The result is 40% greater light
output than a conventional TV and a stunningly
detailed high definition image, along with an
almost complete absence of visible scanlines and
motion artifacts. Of course, traditional Y/Pr/Pb
component video, SCART, S-Video and composite
video outputs are included for use with conventional televisions and projectors.
Multiple Angle: DVDs have the capability to
show up to four different views of the same
scene in a program. When a disc is encoded with
multiple-angle information, pressing the Angle
button will enable you to switch between these
different views. Note that at present, few discs
take advantage of this capability and, when they
do, the multiple-angle technology may only be
present for short periods of time within the disc.
Producers will usually insert some sort of icon or
graphic in the picture to alert you to the
availability of multiple viewing angles.
Reading: This is a message that you will see
after you´ve loaded the disc and the tray has
closed. It refers to the fact that the player must
first examine the contents of the disc to see if it
is a CD or DVD, and then extract the information
about the type of material on the disc, such as
languages, aspect ratios, subtitles, number of
titles and more.The slight delay while the
contents of the disc are read is normal.
Resume: The operation of the Stop Button on
the DVD works differently from what you are
used to on CD players. On a traditional CD player, when you press the Stop button, the unit does
just that: it stops playback. On a CD player, when
you press the start button again, the disc starts
from the beginning. With the DVD, however, you
have two options when playing DVD discs.
Pressing Stop once will stop playback, but it
actually puts the unit in the Resume mode.This
means that you can turn the machine off and,
when you press play the next time, the disc will
resume or continue from the point on the disc
where the Stop button was pressed. This is helpful if you are watching a movie and must interrupt your viewing session but wish to pick up
where you left off. Pressing the Stop button twice
will stop the machine in a traditional manner
and, when the disc is played again, it will start
from the beginning.
In resume mode, the cover of the DVD will be
displayed, if available. Otherwise, the
Harman Kardon screen will appear.
