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:  
– a flat-blade screwdriver  
Use the drive in a horizontal position. Do not use it in a vertical or tilted  
position.  
– 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.  
Setting the Jumpers  
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.  
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.

Mounting a Host Adapter  
Reassembling the Computer  
Install a host adapter in the computer by inserting it securely in a system  
expansion slot. Refer to the operating instructions of the host adapter for  
complete instructions on its installation and the assignment of its switches.  
1 Tuck the cables behind the drives so that they do not come up above the  
power supply.  
Power supply  
Check the following before closing the computer:  
Note:  
Are the connections between the drive and computer correct?  
Are the switches set to the appropriate positions?  
If you connect external SCSI device(s), you must remove a host adapter’s  
terminator resistors.  
2 Slide the computer’s cover on and fasten the cover mounting screws at  
the back of the computer.

Installing the Software Driver  
Using Discs and Caddies  
MSCDEX and the device driver for an ordinary CD-ROM drive can be  
Loading a Caddy with a Disc  
used when using the CDU924S as a SCSI CD-ROM drive.  
Use the device driver for a CD-R drive when using the CDU924S 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.  
1 To open the caddy lid, press the tabs on the both sides of the caddy at  
the end opposite to the shutter.  
2 Set a disc, with its label upward, in the caddy.  
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.

3 Close the lid firmly.  
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  
– high temperature  
– excessive dust  
– direct sunlight  
Care of Discs  
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.  
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.  
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.  
In such a case, eject the caddy and re-insert it properly. If the busy  
indicator remains lit amber, consult your dealer or qualified service  
personnel. The busy indicator also lights amber during audio play.  
However, this is not a malfunction.  
Starting Up  
Ejecting a Caddy  
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.  
1 Turn on the power supply.  
2 Press the eject button on the drive unit.  
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.  
Notes:  
The eject button does not work if it is disabled by the software.  
To eject a caddy when the eject button is disabled by the software:  
– Make sure that the jumper block’s PREVENT/ALLOW is set to ON.  
– Turn the power of your computer off, and turn it on again. (Or reset  
the SCSI bus using a software command.)  
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.
