SERVICING PRECAUTIONS
NOTES REGARDING HANDLING OF THE PICK-UP
1. Notes for transport and storage
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 cot-
ton 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 compo-
nents 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 com-
monly are called Electrostatically Sensitive Devices (ESD). Examples of typical ESD devices are integrated cir-
cuits 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 sur-
face 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 gen-
erate static electricity sufficient to damage an ESD device).

SETUP AND CONNECTIONS
•Ensure that the power switch of this unit (and of
other equipment to be connected) is set to “Off”
before commencing connection.
•Do not block the ventilation holes of any of the
equipment and arrange them so that air can
circulate freely.
•Read through the instructions before connecting
other equipment.
•Ensure that you observe the color-coding when con-
necting audio and video cables.
NOTES:
•The video output (yellow) combines the complete
video signal (composite) and sends it to the TV
(or to the A/V receiver) by one cable only. Use the
video output when your TV set is equipped with
a video input jack only.
•The S-Video output connector separates the color (C)
and luminance (Y) signals before transmitting them to
the TV set in order to achieve a sharper picture. Use
the S-Video cable when connecting the player to a
TV equipped with an S-Video input for improved
picture clarity. Never connect both outputs, video
and S-Video, to your TV or A/V receiver; use only
one of them.
•When the audio signal is to be fed to an analog
receiver rather than to the TV, connect the audio out
jacks to any analog audio input on your amplifier/
decoder/receiver. The DVD 22 will “downmix”
Dolby Digital recordings to Pro Logic.* For more
information see the IMPORTANT NOTE on next
page.

SETUP AND CONNECTIONS 13
SETUP AND CONNECTIONS
• One of the major advantages of the DVD format is
its ability to use a variety of digital audio formats for
the ultimate in sonic performance. However, in order
to enjoy the benefits of digital audio, you must use a
receiver or processor that has digital audio decoding
capabilities and make an optical or coaxial digital
audio connection between the DVD 22 and your
home theater system. This simple connection is
made as shown below with an optional coax or
optical cable. Note that only one of these connec-
tions is required, and the choice is determined by
personal preferences, as well as the number of
inputs available on your receiver or processor as
compared to the number of digital audio sources it
must accommodate.
• When your receiver or processor does not have
digital audio capability, connect the left/right audio
outputs (red/white colored jacks) to an available
left/right audio input on your receiver or processor.
You may also connect these outputs directly to the
left/right audio inputs on a television or video display
when an analog stereo or multichannel receiver is
not used.
• Even when making a digital audio connection, we
recommend that you also connect the left/right
analog audio outputs of the DVD 22 to your receiver
or processor. While your primary listening will be
done using multichannel audio that is decoded from
the digital audio input, some receivers and proces-
sors also require an analog connection for use with
multizone systems or recording outputs. This optional
connection is shown below.

• When both composite (yellow) and S-Video jacks
(but not component inputs) are available on the
video display, we recommend using the S-Video
connection for higher video quality.
• If your receiver or processor has video switching
capability, we recommend that the composite or
S-Video outputs of the DVD 22 be connected to
the receiver or processor, along with the output
of other video sources in your system, such as a
VCR and cable or satellite receiver. This simplifies
the operation of your system since the receiver
or processor will switch multiple sources and
feed the selected output to the display.
• If your television, monitor, projector or video display
has component video inputs, we strongly recom-
mend that you connect the Y/Pr/Pb (green/red/blue)
video output jacks on the DVD 22 to the matching
video inputs on your receiver or processor, or
directly to the inputs on your television or other
video display.
• If your receiver or processor has component
video switching capability, we recommend that
the video outputs of the DVD 22 be connected
to the receiver or processor, along with the out-
put of other component video sources in your
system, such as an HDTV tuner or cable or satel-
lite receiver. This simplifies the operation of your
system since the receiver or processor will switch
multiple sources and feed the selected output to
the display.
• If your video display is compatible with high-
resolution video signals, be certain that the
connections are made to the input jacks on the
display marked “HD Component,” if available.
• If your video display is compatible with high-
resolution video signals, you may need to
configure the input settings on the display for
use with “480P” input signals.
• If you use the component video outputs with
a video display that is compatible with high-
resolution video signals, the DVD 22’s video
output should be changed from Interlaced to
Progressive, as shown on page 20.
• When the component video outputs are used, we
recommend that you also connect the standard
composite or S-Video outputs to your receiver or
processor so that standard-rate video signals are
available for use with the multizone or record
outputs, where applicable.

Video Display Connections
IMPORTANT NOTE: Make certain that any device
being connected, including the DVD 22, your receiver
or processor, and your TV or video display, are turned
off whenever you make connections between products.
NOTES:
•If an S-Video or composite video connection is
made either as your primary video connection or in
addition to a component video connection for use in
feeding a multizone system or recorder, note that
you may make either type of connection, but not
both. Only one type is needed.
•When video connections are made to an A/V
receiver, surround processor or other device that
switches the video signals, make the connections
between that device and your video display in
accordance with the instructions for that product.
Depending on the capabilities of the receiver,
processor or other switcher, you may need to
make both composite or S-Video and component
video connections.

For Your Reference:
•Dolby Digital is a digital sound compression
technique developed by the Dolby Laboratories
Licensing Corporation. Supporting 5.1- or 7.1-
channel surround sound depending on the specific
disc, as well as stereo (2-channel) sound, this tech-
nique enables a large quantity of sound data to be
efficiently recorded on a disc.
• DTS is another digital audio technology developed
by Digital Theater Systems, Inc. It supports 5.1 and
6.1 surround sound, depending on the specific disc,
thanks to a sophisticated encoding system.
•Linear PCM is a signal recording format used in
CDs. While CDs are recorded in 44.1kHz/16-bit,
DVDs are recorded in 48kHz/16-bit up to 96kHz/
24-bit.
•If you have a Dolby Pro Logic Surround decoder
connected to the DVD 22’s analog audio out con-
nectors, thanks to the “Downmix” function of the
DVD 22 you will obtain the full benefit of Pro Logic
from the same DVD movies that provide full 5.1-
channel Dolby Digital soundtracks, as well as from
titles encoded with Dolby Surround.
•The DVD 22 is designed to digitally output 96kHz
PCM audio with a 96kHz sampling rate. The 96kHz
indicator will light in the display. However, some
96kHz DVDs may include copy protection codes
that do not permit digital output. For full 96kHz
fidelity from these discs, use the analog outputs of
the DVD 22. If your surround processor converter
does not support 96kHz PCM audio, you must use
the DVD 22 analog outputs for full 96kHz fidelity
with these discs.
•When connecting a receiver or surround processor
with a digital input but which does not contain a
Dolby Digital or DTS decoder, be sure to select
PCM as the initial setting in the Digital Output menu
(see page 18). Otherwise, any attempt to play
DVDs may cause such a high level of noise
that it may be harmful to your ears and damage
your speakers.
•
CDs can be played as they would in a conventional
CD player.
Dolby Digital and DTS
Both Dolby Digital and DTS are audio formats used to
record 5.1-channel audio signals onto the digital track
of film. Both of these formats provide six separate
channels: left, right, center, left rear, right rear, and
common subwoofer.
Remember that Dolby Digital or DTS will only play
5.1-channel sound if you’ve connected the optical or
coaxial output of the DVD 22 to a DTS or Dolby Digital
receiver or decoder (see page 13) and if the disc was
recorded in the Dolby Digital or DTS format.
NOTE: Some first-generation DTS decoders that do
not support DVD-DTS interface may not work properly
with the DVD/CD player.
