Precautions
Installing the Drive Unit into the Computer
■ Installation
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.
●
Avoid placing the drive in a location subject to:
– high humidity
– high temperature
– excessive dust
Getting Started
– mechanical vibration
– direct sunlight.
●
Prepare the necessary parts and tools that have not been supplied:
– Screwdriver
Use the drive in a horizontal or vertical position. Do not use it in a tilted
position.
– four screws 3 mm in diameter (Screws must not extend more than
4.0 mm into the side panels or the bottom plate.)
– two mounting rails if your computer has mounting tracks.
Unplug the computer and disconnect the cables attached to the
back for your own safety. Do not turn on the power of the computer
before completing the entire installation process.
■ 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.
Setting the Jumpers
Set the jumpers on the rear panel of the drive unit in accordance with the
configuration of your computer system.
The jumpers are preset, as illustrated below, at the factory.
■ Transportation
●
Keep the original packing materials for future transport of the drive.

Use the device driver for a CD-R drive when using the CDU926S as a
recordable drive.
Be sure to install the device driver before operating the drive. Refer to the
manual supplied with the host adapter for instructions.
●
●
If the CD-R drive isn’t the last device at the SCSI bus, remove the
termination from the CD-R drive and make sure that the last device at
the SCSI bus has a proper termination installed.
Be aware that the SCSI bus needs to be terminated at each end of the
SCSI bus cable.
Closing the Computer
1 Replace the cover on the computer, being careful to reinstall all
screws that were removed.

3 Close the lid firmly.
Loading a Caddy with a Disc
1 To open the caddy lid, press the tabs on the both sides of the caddy at
the end opposite to the shutter.
Important:
●
Do not drop the disc or the caddy.
●
The caddy is designed so that its shutter automatically opens when it is
inserted into the drive unit. Do not open the shutter manually and touch
the disc.
2 Set a disc, with its label upward, in the caddy.
●
Data cannot be recorded if the recording surface is contaminated.
Be careful not to touch the recording surface when setting a CD-R disc
in the caddy. Data cannot be recorded if the recording surface is
contaminated.
●
The caddy is precisely adjusted at the factory. Do not disassemble it.

Operating the Drive
Make sure that the application software is installed in the host computer
before using the drive.
Storing Discs and Caddies
●
●
Remove the caddy from the drive unit before moving the drive.
Do not store the disc and caddy in a location subject to:
– high humidity
Starting Up
– high temperature
– excessive dust
– direct sunlight
1 Turn on the power supply.
2 Insert the caddy into the drive slot with the disc’s label facing up, and
push it partially into the drive until the automatic loading mechanism
pulls the caddy in.
Care of Discs
Important:
When inserting the caddy, let the automatic loading mechanism pull it into
the drive by itself. Do not hold onto the caddy or attempt to overpower the
loading mechanism.
●
●
●
Hold the disc by its edge. Do not touch the surface.
Wipe the CD-ROM disc with the optional CD cleaner to clean it.
Do not wipe a CD-R disc with a cleaner before recording data. To avoid
scratching the recording surface, blow away dust using an air blower.
The drive begins reading the Table of Contents (TOC) data. The busy
indicator lights amber while the TOC data is being read.
When the busy indicator changes to green, the drive is ready to receive
commands, and data may be retrieved from the disc.
After loading the CD-R disc, it takes a moment for the drive to become
ready while the Program Memory Area is read.
From here on, follow the instructions provided with the application
software.
Notes:
●
The drive unit does not allow a caddy to be inserted if:
– PREVENT/ALLOW of the jumper block is set to OFF.
– the host computer is set to the PREVENT mode by the software.
The busy indicator keeps on lighting amber if:
– the disc is not properly inserted.
●
– a malfunction occurs.
