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.

Termination
• If the CD-R drive is connected at the end of the SCSI chain, keep
the drive terminator mounted at the drive.
• 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.

• 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.

21
Operating the Drive
Make sure that the application software is installed in the host
computer before using the drive.
Starting Up
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.
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.
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.
22
Operating 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.
Ejecting a Caddy
1 Turn on the power supply.
2 Press the eject button on the drive unit.
CD Caddy
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:

ON.
–Turn the power of your computer off, and turn it on again. (Or
reset the SCSI bus using a software command.)
