setup. In some cases, you will need to install additional software to make use of all the
features of the COMBO drive.
To use the COMBO drive on a computer:
 As a CD-ROM drive: Most Windows Operating Systems (Windows XP,
Windows ME, Windows 2000, Windows 98, and Windows 95) supply a generic
CD-ROM device driver that allows the COMBO drive to function as a standard
CD-ROM drive. You do not need to install anything else.
 As a DVD-ROM drive: The computer’s operating system (excluding Windows 95)
also allows the COMBO drive to function as a DVD-ROM drive. You do not need
to install anything else to play DVDs. (In Windows 95, you will need additional
software to play DVD media, which will be included with the COMBO drive
software CD kit.)
 As a CD-R/CD-RW drive: In order to write to CD-R or CD-RW media, you will
need additional software. The Recording software kit included with the package
will offer you function like mastering CDs, backing up your hard disk or files,
capturing audio, duplicating CDs, and more.
Loading and Unloading the Tray
(1) While the COMBO drive is powered up, push the Eject button on the front
panel. The tray drawer slides out in a few seconds.

PLAYING CDS & DVDS
Playback Software
You must install the DVD playback software to your computer first. If you do not have any
DVD playback software installed in your computer, the included DVD playback software in
the CD kit will bring you the best playback result.
You can immediately play Audio CDs and pre-recorded DVD discs, including movies and
other DVDs. To play a CD or a Digital Video Disc (DVD), insert the disc with the label up
(for CDs). This COMBO drive plays both single-layer and dual-layer DVDs.
Playing Audio CDs
In order to listen to an audio CD, connect an audio cable to the analog audio connector on the
rear of the drive and connect the other end to your sound board.
To listen to music through the computer’s sound board, you can control volume with the
volume control on the Windows Media Player or CD Player Taskbar. You can also mute the
sound on your sound board and listen to music through headphones or self-powered speakers.

Playing DVDs for the First Time
A code on some DVDs allows them to be played only in a certain regional area, such as North
America, Europe, etc. When the COMBO drive ships, there is no region code set. The first
time a DVD that has a region setting is inserted into the COMBO drive, the act of inserting
the DVD sets the drive to that region code.
If you later insert a DVD with a different region code, you are prompted to either accept
changing the region code or not. If you do not accept the change, then that DVD will not play.
If you do accept the change, then the COMBO drive’s region code setting is changed. But
advised that you may change the COMBO drive’s region code only 5 times. After that,
you will not be able to change your drive’s code setting.
