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
