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.
