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 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).

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 connecting 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 connections 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 processors also require an analog connection for use with multizone systems or recording outputs.This optional connection is shown below.

SETUP AND CONNECTIONS

• If your television, monitor, projector or video display has standard composite and S-Video connections only, connect one or the other (but not both) either to the matching video inputs on your receiver or processor, or directly to the inputs on your television or other video display.

• 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 recommend 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 output of other component video sources in your system, such as an HDTV tuner or 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 video display is compatible with highresolution 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 highresolution 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 highresolution 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.

Digital format must be selected as “Original” or “PCM” in Digital Output menu (see “Digital Output” section on page 19).

For Your Reference:

• Dolby Digital is a digital sound compression technique developed by the Dolby Laboratories Licensing Corporation. Supporting 5.1- or 7.1channel surround sound depending on the specific disc, as well as stereo (2-channel) sound, this technique 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 connectors, 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 5.1channel 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.
