Installation, Usage and Handling Precautions

lnstallation

[

Avoid placing the drive in a location subject to :

- high humidity

- high temperature

- mechanical vibration

- direct sunlight

Operation

[

- During operation, excessive vibration or a sudden jolt to the drive may

cause a malfunction.

- Avoid exposing the drive to sudden changes in temperature. This may

cause condensation to collect inside the drive.

- Do not use damaged, cracked, or warped discs.

Transportation

[

- Always remove the disc before moving the drive.

Troubleshooting

* When the CD-ROM drive does not work with the hard disk drive in primary

IDE channel.

(SOLUTION)

1. Check the CD-ROM drive Master/Slave Jumper setting.
The CD-ROM drive must be set to the Slave mode.

2. Check to be sure your hard disk Interface type is IDE type.

3. Check your hard disk Master/Slave Jumper setting.
Some old-version IDE type hard disks were set to Master Only mode.
In that case, contact your hard disk company and change your hard disk
jumper setting to master mode.

4. If the CD-ROM drive does not work with above methods, you may need a
secondary IDE card. If you use the secondar y IDE card, you should set the
CD-ROM drive jumper to the master mode if the CD-ROM drive is the first
device you are connecting to the secondary IDE card.

* When the CD-ROM drive does not install in OS/2 warp.

(SOLUTION)

1. Select NON-LISTED IDE CD.

* CD-ROM drive is not present in Windows 3.1 or 3.11 or DOSSHELL.

(SOLUTION)

1. When the WIN or DOSSHELL command lines are present in your
AUTOEXEC.BAT, make sure that the MSCDEX.EXE command line appears
before the WIN or the DOSSHELL command lines.

NOTE: For more information, consult the README.TXT file of the supplied Setup

Diskette.
