3. Using Your Notebook PC
3-3-6 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.
POINTS
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.
3-3-6 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.
CAUTION
Prolonged use of the optical drive drive, such as watching a DVD
movie, will substantially reduce your notebook PC’s battery life.
Many movie run-times are longer than your system can support
on a single 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.
