To use the CD-ROM drive unit, the following components are required:
●Computer (IBM PC, PC/XT, PC/AT, HP Vectra, or equivalent)
●Host adapter
●Floppy disk drive
●Interface cable (50 to 50 pin flat cable)

Precautions
■Installation
●Avoid placing the drive in a location subject to:
– high humidity
– high temperature
– excessive dust
– mechanical vibration
– direct sunlight
●The drive can be used in either a horizontal or vertical position.
●Do not force the power cable. It is keyed to protect the drive.
■Operation
●Do not move the drive when it is in use. Doing so may cause data error
and damage the optical pick-up.
●Avoid exposing the drive to sudden changes in temperature as
condensation may form on the lens inside the drive. Should the
surrounding temperature suddenly rise while the drive is turned on, stop
using the drive and leave the power on at least one hour before
operating it or turning it off. Operating the drive immediately after a
sudden increase in temperature may result in a malfunction.
■Transportation
●Close the disc drawer before moving the drive.
●Keep the original packing materials. When you need to ship the drive to
another location, repacking it in its original container will help you
transport it safely.

Notes:
●The lower row of pins are ground.
●ID SELECT, PREVENT/ALLOW, and TEST MODE are recognized
only when the power is turned on or SCSI is reset.
●TEST MODE is reserved for use at the factory only. Do not put a
jumper over TEST MODE pins. Doing so may cause an unexpected
result.

Operating the Drive
This section describes how to start the drive and eject a disc.
Starting the Drive
1Turn on the power of your computer.
2Press the eject button.
The drawer comes out automatically.
3Place a disc in the drawer with its label side up.
Operating the Drive 21
Installing the Software Driver
The MSCDEX (or equivalent) and a device driver for the CD-ROM
drive are supplied with the host adapter. Install both the MSCDEX
(or equivalent) and the device driver in order to use the CD-ROM drive.
Refer to the manual supplied with the host adapter for instructions.
20 Installing the Software Driver
Place a disc with
its label side up.
Press the eject button.

Ejecting the Disc
To eject the disc, press the eject button on the front panel. The drawer
comes out automatically.
Note:
The eject button does not work if it is disabled by:
- the software you are using
- the PREVENT/ALLOW jumper
■Opening the drawer manually in an emergency
You can open the drawer manually when it fails to come out by means of
the eject button or software commands. To do this, follow the procedure
below:
1Turn off the power of your computer.
2Insert a pointed object, such as a paper clip, into the emergency eject
hole and push.
After removing a disc from the drive unit, consult your dealer or qualified
service personnel.
Operating the Drive 23
Note:
When the drive is set up in vertical position, use the appropriate disc locks
to prevent your disc from falling.
4Gently push the drawer or press the eject button to close the drawer.
The drive may begin reading the Table of Contents (TOC) data when it
accepts the disc. The busy indicator lights up in amber while the drive
is reading the TOC.
For subsequent drive operations, follow the instructions provided with
the application software you are using.
Note:
The busy indicator stays lit in amber if:
– the disc is not properly placed on the loading tray
– a malfunction occurs.
In either case, eject the disc and place it in the loading tray again making
sure that it sits properly in the tray. If doing this does not solve the
problem and the busy indicator still remains lit in amber, consult your
dealer or qualified service personnel.
Caution: Do not forcibly close the disc drawer. Applying excessive force
may damage the loading mechanism. The tray’s mechanism is designed to
operate with a “feather touch”.
