Important Precautions

Follow these precautions when handling the drive or discs.

Precautions

Installation

Operation

• Please take notice that the manufacturer of this equipment does
not offer any warranty against data loss due to inappropriate
installation or handling, or direct or indirect damages.

• Please take notice that the manufacturer will bear no
responsibility for direct or indirect damages caused by the use of
this product or its malfunction.

• Please take notice that the manufacturer will bear no
responsibility for damage to data caused by this product.

• Please backup (copy) all important data as protection against
data loss.

• Avoid placing the drive in a location subject to:

- high humidity

- high temperature

- excessive dust

- mechanical vibration

- direct sunlight

We recommend using the drive in a horizontal position.
Do not use it in a tilted or vertical position.

• Don’t move the drive suddenly from a cold place to a warm one or
raise the room temperature suddenly. Condensation may occur,
causing abnormal operation.

• Make sure to remove the disc before moving the drive. The disc
may be damaged, causing data loss.

• Be careful to prevent foreign objects, such as liquids or metal,
from entering the drive. In case a foreign object enters the drive,
please consult the dealer where the drive was purchased.

• Don’t interrupt the electric power while the drive is operating.

• When connecting two IDE devices to the Primary or Secondary
connectors, make sure that the two devices are not configured as
both Master, or both Slave. If they are both set the same,
Windows may fail to run or recognize the drives.

• The total length of the IDE cable should be no more than 18
inches (about 45 cm).

Connects to the power supply (5-and 12-V DC) of the host computer.
NOTE : Be careful to connect with the proper polarity. Connecting the
wrong way may damage the system (and is not guaranteed). Usually this
connector can only be attached one way.

2. IDE Interface Connector

Connect to the IDE (Integrated Device Electronics) Interface using a 40­pin flat IDE cable.
NOTE : Do not connect or disconnect the cable when the power is on,
as this could cause a short circuit and damage the system. Always turn
the power OFF when connecting or disconnecting the cable.

3. Jumper Connector

This jumper determines whether the drive is configured as a master or
slave. Changing the master-slave configuration takes effect after power­on reset.

4. Analog Audio Output Connector

Provides output to a sound card (analog signal). Generally you need this
to play a regular audio CD.

5. Digital Audio Output Connector

Provides output to a sound card (digital Signal).

Jumper

Setup

Before installation, set the jumper on the jumper connector on the
rear panel.
The drive can be connected as the Master or Slave on an EIDE
(ATAPI) interface. When several (up to four) EIDE devices are
connected, each must be set in a unique way. Specific knowledge
of hardware and software is necessary to install the drive.

NOTE : If two peripheral devices with the same settings are both
connected to the Primary or to the Secondary EIDE bus, the host
computer may fail to run or may malfunction. Careful attention is
necessary.

Device Drivers

When using Windows 98/95 or Window NT Workstation Ver.4.0, no
special device driver is required.

The Setup

Process

This CD-R/RW drive is supplied with MS-DOS drivers on a 3
floppy disk. These drivers are required to use the CD-R/RW drive in
DOS or to enable the CD-ROM disk. Drivers for other Operating
Systems are not normally required or available as they usually have
a generic IDE, E-IDE/ATAPI CD-ROM driver built in (Windows 95,
98, NT 3.51 and higher and OS/2 Warp 3 are such examples).
If it is necessary to edit any file manually, first make a backup copy
on a floppy, then the original file, then save the changed file to your
hard drive, exit and re-boot PC to ensure the change will be
implemented.

For non-Windows 95/98/NT and OS/2 Warp 3
Installation

The INSTALLprogram performs the following functions:

¥ Allows the user to select the target drive and directory in DOS.
¥ Unless modified by the user, the INSTALL program searches the

target drive for the directory (\CDROM): if this is not found, the
directory will be created.

¥ Copies the CD-R/RW device driver file named GSCDROM.SYS,

the Microsoft CD-ROM Extension file named MSCDEX.EXE and
the utility files to the specified directory.

¥ Modifies your CONFIG.SYS file to list the location and name of

the device driver.

v2.5b(s) Operation

How to Use the Discs

When using CD-ROM discs, CD-R discs or CD-RW discs, don’t
attach any stickers or labels to the discs. Using discs with them
attached not only causes read and write errors, but data on the disc
may be lost due to damage to the disc itself.

Emergency

Eject

This drive has a function that allows the CD to be ejected manually
if this becomes necessary in an emergency, such as failure of the
drive or a power outage.

NOTE: Don’t use this feature except in an emergency.

1) Turn the power to OFF.

2) Poke a fine-tipped object (such as a straightened heavy duty
paper clip) into the small hole above the eject button. The front
door will pop open and the disk tray will come partway out.

3) Pull the front door to open it all the way, then grip the disc tray
between thumb and forefinger and gently pull it straight out.

NOTE: This feature is a last measure to be used only in an
emergency. Using it excessively will cause malfunction.
* If you cannot get a good grip on the disc tray with your fingers, use

Troubleshooting

Before

Requesting

Service

Before calling for service, check this list.
¥ The drive doesn’t have power.

• Is the power supply cable from the host computer plugged in?

• Is the Power Connector to the drive securely attached?

¥ The system doesn’t start.

• Are the Primary and Secondary connections and the Master
and Slave settings correct?

• Is the total length of the IDE cable 18 inches or less?

• Is each connector completely attached?
Movement of the PC may loosen connections.

¥ Cannot Read or Write Discs.

• Is the condition of everything else in the system (CPU, hard
disc, and others) as it should be? (See system environment
page 4.)

• Does the CD-R or CD-RW disc have dirt or scratches?

• Did a screen saver or other application operate while writing to
the disc?

• Is there enough free space on the CD-R/RW disc?

• Does writing fail even using the simulation test?

• Is the disc loaded in the drive with the read/write surface facing
the right direction? (label up)

• Is the drive installed in the correct orientation?

• Was the drive or disc moved from a low temperature
environment to a high temperature environment? (There is a
possibility of condensation on the lens in the drive or on the
surface of the disc.)

When you call for service, be prepared to give as much information
as possible of your system, environment, and the specific problem.
(What happened? When? How long? What was going on? Were
there any error messages displayed? etc.)
