Disc Tray
This is the tray for the disc. Place the disc on the ejected disc tray, then
lightly push the tray (or push the eject button) and the CD will be loaded.
NOTE: Don't pull out or
push in the disc tray forcibly. This might cause damage to the loading section
of the drive.
Eject Button
Press this button to open the CD tray. This button works only when power is
supplied to the drive.
Emergency Eject Hole
The emergency eject hole is to be used only when the CD tray will not open when
Stop/Eject button is pressed.
Drive Activity Indicator
This LED is used to indicate the operation of CD-RW/DVD-ROM Drive.
How to Use the Discs
When using CD-ROM discs, DVD-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.
The Discs in this unit operate at a very high speed!
DO NOT use damaged, cracked or warped discs. The drive's optical unit may be
damaged if they break.
DO NOT use non-standard discs. Non-standard discs may not play or store data
properly.
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.
Turn the power to OFF.
Poke a fine-tipped object (such as a straightened heavy duty paper clip) into
the small hole above the eject button ( See figure 2.).
The front door will pop open and the disk tray will come partway out.
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.
Figure 2.
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 a steel binder clip or spring clamp to pull it out.
NOTE: Don't pull out or
push in the disc tray forcibly. This might cause damage to the loading section
of the drive.
