USING DOLBY™ HEADPHONE
The Dolby Headphone utility lets you enjoy multi-channel sound sources, such as DVD
movies, with realistic surround sound using your
conventional
stereo headphones. The
Dolby Headphone is a utility that is available in the DVD player software.
Media discs which do not have the Dolby Surround 5:1 symbol
will not support Dolby Headphone.
After making changes to the Dolby Headphone feature and
clicking OK, wait at least ten seconds before making another
change in order to allow the system to stabilize.
To use the Dolby Headphone feature, perform the following steps:
1. Double click the DVD player application icon on your desktop.
2. On the toolbar that appears, click the
Properties
button (the fourth button from the
left, with the image of a wrench).
3. On the Properties window, select the
Dolby Headphone
tab.
4. To enable Dolby Headphone, check the
Enable Dolby Headphone
box. To
change the type of surround sound, select one of the radio buttons listed under
Room Filter Setting.
5. Click
OK
. The Dolby Headphone feature will now be enabled until you disable it by
unchecking Enable Dolby Headphone.

USING THE OPTICAL DRIVE ON BATTERY POWER
Since optical drive drives consume a lot of power, your overall battery life will be
significantly shorter when operating the optical drive drive continuously (such as watch-
ing a DVD movie) than during standard operation. Many movies run-times are longer than
your notebook PC can support on a single charged battery. If you are watching a DVD
movie on battery power you may need to swap in an additional, charged battery or
attach AC power during the movie to view it in its entirety.
Prolonged use of the optical drive drive, such as watching a DVD
movie, will substantially reduce your notebook PC’s battery life.
