SERVICING NOTES

NOTES ON HANDLING THE OPTICAL PICK-UP BLOCK OR BASE UNIT

System requirements

The following hardware and software are required in order to use the SonicStage software for the Net MD.

The laser diode in the optical pick-up block may suffer electro- static 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

Never look into the laser diode emission from right above when checking it for adjustment. It is feared that you will lose your sight.

NOTES ON HANDLING THE OPTICAL PICK-UP BLOCK (LCX-5R)

The laser diode in the optical pick-up block may suffer electro- static break-down easily. When handling it, perform soldering bridge to the laser-tap on the flexible board. Also perform mea- sures against electrostatic break-down sufficiently before the op- eration. The flexible board is easily damaged and should be handled with care.

1)Note on hard disk drive space

120 MB or more free space on the hard disk drive is required. If your computer does not have enough space, the software will not be properly installed. The required free space differs according to the version of your Windows OS, or the amount of audio files that you handle.

This software is not supported by the following environments:

•Macintosh

•Windows XP versions other than Home Edition or Professional

•Windows 2000 versions other than Professional

•Windows 98 versions other than Second Edition

•Windows NT

•Windows 95

•Personally constructed PCs or operating systems

•An environment that is an upgrade of the original manufacturer-installed operating system

•Multi-boot environment

•Multi-monitor environment

Notes

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

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

OPTICAL PICK-UP FLEXIBLE BOARD

¥In performing the repair with the power supplied to the set, re- moving the MAIN board causes the set to be disabled.

In such a case, make a solder bridge to short SL802 (OPEN/ CLOSE) on the MAIN board.
