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.

System requirements

The following system environment is required in order to use the SonicStage/MD Simple Burner software.

Computer IBM PC/AT or Compatible

• CPU: Pentium III 450 MHz or higher

• Hard disk drive space: 200 MB or more (1.5 GB or more is recommended)

(The amount space will vary according to Windows version and the number of music ﬁles stored on the hard disk.)

• RAM: 128 MB or more Others • CD drive (capable of digital playback by WDM) (A CD-R/RW

drive is necessary for CD writing)

• Sound Board

• USB port

Operating System

Factory installed: Windows XP Media Center Edition 2005/Windows XP Media Center Edition 2004/Windows XP Media Center Edition/Windows XP Professional/Windows XP Home Edition/Windows 2000 Professional (Service Pack 3 or later)/ Windows Millennium Edition/Windows 98 Second Edition

better is recommended)

Others • Internet access for online registration and CDDB use

• Internet access and Microsoft Internet Explorer (version 5.5 or higher) for use

of EMD services

• Windows Media Player (version 7.0 or higher) installed for playing WMA

ﬁles

This software is not supported by operating systems other than those listed above, custom-built PCs, operating systems that are upgrades from the original manufacturer-installed system, multiboot environments, multi-monitor environments, or Macintosh computers.

Notes

• We do not ensure trouble-free operation on all computers that satisfy the system requirements.

• The NTFS format of Windows XP/Windows 2000 Professional can be used only with the standard (factory)

settings.

• We do not ensure trouble-free operation of the system suspend, sleep, or hibernation function on all computers.

SECTION 1

SERVICING NOTES

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.

OPERATION CHECK WHEN THE MAIN BOARD IS REMOVED

In making an operation check with the MAIN board removed from the set, short the SL463 of the MAIN board with the solder before starting the operation check.

Note: Be sure to remove the solder used for shortcircuit after the repaire

completed.

– MAIN Board (Conductor Side) –

SL463

NOTES ON REPLACEMENT OF CSP (CHIP SIZE PACKAGE) IC

Replacement of IC401, IC501, IC601 and IC701 on the MAIN board used in this set requires a special tool.

NOTES ON REPLACEMENT OF IC801 ON THE MAIN BOARD

IC801 on the MAIN board can not be exchanged alone. When IC801 on the MAIN board is damaged, exchange the complete MAIN board.

NOTES ON REPLACEMENT OF IC1 AND S8 ON THE OLED BOARD

IC1 and S8 on the OLED board can not be exchanged alone. When IC1 and S8 on the OLED board are damaged, exchange the complete OLED board.
