SERVICING NOTES

HCD-GTX999

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 ﬂ exible 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 reﬂ ective 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 viscous (sticky, less prone to ﬂ ow)

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.

RELEASING THE DISC TRAY LOCK

The disc tray lock function for the antitheft of an demonstration disc in the store is equipped.

NOTE THE IC5 AND IC13 ON THE USB MICOM BOARD REPLACING

• Audio CD

• CD-R/CD-RW (audio data/MP3 ﬁ les)

Discs that this system CANNOT play

• CD-ROM

• CD-R/CD-RW other than those recorded in music CD format or MP3

format conforming to ISO9660 Level 1/Level 2, Joliet

• CD-R/CD-RW recorded in multisession that have not ended by “closing

the session”

• CD-R/CD-RW of poor recording quality, CD-R/CD-RW that have

scratches or are dirty, or CD-R/CDRW recorded with an incompatible recording device

• Discs of non-standard shape (for example, heart, square, star)

• Discs that have adhesive tape, paper, or sticker attached to them

• Rental or used discs with attached seals where the glue extends beyond

the seal

• Discs that have labels printed using ink that feels tacky when touched

Notes on discs

• Before playing, wipe the disc with a cleaning cloth from the centre out to

the edge.

• Do not clean discs with solvents, such as benzine thinner, or commer-

cially available cleaners or anti-static spray intended for vinyl LPs.

• Do not expose discs to direct sunlight or heat sources such as hot air

ducts, nor leave it in a car parked in direct sunlight.

• Do not use a commercial cleaning disc as it may cause the unit to mal-

function.

On safety

• Completely disconnect the power cord (mains lead) from the wall outlet

(mains) if it is not going to be used for an extended period of time. When unplugging the unit, always grip the plug. Never pull the cord itself.

• Should any solid object or liquid get into the system, unplug the system,

and have it checked by qualiﬁ ed personnel before operating it again.

• AC power cord must be changed only at the qualiﬁ ed service shop.

Consideration for others

Keep the volume at a moderate level out of consideration of your neighbors, especially at night.

About the Hard Disk Drive

Because of its high storage density, the hard disk drive can read and write data a very high speeds. It is, however, easily damaged by mechanical vibration, shock, or dust. Although the hard disk drive is equipped with safety mechanisms to prevent the lost of data due to these factors, the following precautions should be taken during the handling of the system.

• Do not subject the system to strong shocks or vibrations.

• Do not place the system in a location subject to mechanical vibration or

at an unstable location.

• Do not move the system while the power cord is connected to a wall

outlet.

• Do not disconnect the power cord while the system is recording or play-

ing a track.

•

Do not use the system in a place subject to extreme changes in temperature (a temperature gradient greater than 18°F (10°C)/hour).

• Do not attempt to replace or upgrade the hard disk drive by yourself, as

this may cause the system to malfunction. Sony cannot provide compensation for any loss of data caused by a damaged hard disk drive.

Note on the power cord

Before you unplug the power cord from the wall outlet, make sure that the system is turned off. If you unplug the power cord while the system is operating, data that was recorded may be lost or the system may malfunction.

Cleaning the cabinet

Clean this system with a soft cloth slightly moistened with a mild detergent solution. Do not use any type of abrasive pad, scouring powder, or solvent, such as thinner, benzine, or alcohol.

Note on playing MP3/WMA/AAC ﬁ les

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

On placement

• Do not place the system in an inclined position or in locations that are ex-

tremely hot, cold, dusty, dirty, or humid or lacking adequate ventilation, or subject to vibration, direct sunlight or a bright light.

• Be careful when placing the unit or speakers on surfaces that have been

specially treated (for example, with wax, oil, polish) as staining or discoloration of the surface may result.

• If the system is brought directly from a cold to a warm location or is

placed in a very damp room, moisture may condense on the lens inside the CD player, and cause the system to malfunction. In this situation, remove the disc, and leave the system turned on for about an hour until the moisture evaporates.

On heat buildup

• Heat buildup on the unit during operation is normal and is not cause for

alarm.

• Do not touch the cabinet if it has been used continuously at a high volume

because the cabinet may have become hot.

• Do not obstruct the ventilation holes.

On the speaker system

This speaker system is not magnetically shielded, and the picture on nearby TV sets may become magnetically distorted. In this situation, turn off the TV, wait 15 to 30 minutes, and turn it back on. If there is no improvement, move the speakers far away from the TV.

On volume adjustment

CDs reproduce sound with considerably less noise than vinyl records. For this reason, if you raise the volume while listening to a segment containing only noise (as you might do in the case of a vinyl record), a sudden output of highvolume sound may cause damage to the speakers. Make sure to lower the volume before the start of playback.
