Location and Function of Parts and Controls

Precautions

■Installation

• Avoid placing the drive in a location subject to:

–high humidity

–high temperature

–excessive dust

–mechanical vibration

–direct sunlight.

We recommend to use the drive in a horizontal position. Do not use

it in a tilted position.

■Operation

• Do not move the drive during operation. This may cause it to

malfunction during reading or writing.

• Avoid exposing the drive to sudden changes in temperature as

condensation may form on the lens inside the drive as a result.

Should the surrounding temperature suddenly rise while the drive

is on, wait at least one hour before you turn off the power.

Operating the drive immediately after a sudden increase in

temperature, may result in a malfunction during reading or

writing.

■Transportation

• Keep the original packing materials for future transport of the

drive.

• Remove the caddy before moving the drive and, if you take the

drive out of the computer, repack the drive as you received it.

Precautions

Example of System Setup

To use the CD-R device, the following components are required:

• Computer (IBM-PC/AT* compatible)

• SCSI-Host adapter

• SCSI-Interface cable (50 to 50 pin flat cable)

• Software (Device driver, utilities)

Example of System Setup

* IBM-PC/AT is a registered trademark of International Business Machines

Corporation.

Installing the Drive Unit into the Computer

As you go through this section, you may wish to refer to your

computer’s manual for a more detailed description of how to install

internal drives.

Getting Started
