USING DOLBY™ HEADPHONE

The Dolby Headphone utility lets you enjoy multi- channel sound sources, such as DVD movies, with real- istic virtual surround sound using conventional stereo headphones. The Dolby Headphone is a utility that is available in the InterVideo WinDVD application.

Dolby Headphone is a signal processing system that enables your stereo headphones to realistically emulate the sound of a five-speaker playback system.

P O I N T S

■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 InterVideo WinDVD 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 Head- phone 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 MEDIA PLAYER ON

BATTERY POWER

Since media player drives consume a lot of power, your overall battery life will be significantly shorter when oper- ating the media player drive continuously (such as watching a DVD movie) than during standard operation. Many movies run-times are longer than your LifeBook notebook 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.

P O I N T

■Prolonged use of the media player drive, such as watching a DVD movie, will substantially reduce your LifeBook notebook’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.

■An additional fully-charged battery is highly recom- mended if you will be watching DVD movies on battery power. If you don’t have an additional battery, you may purchase one either online at www.fujitsupc.com or by calling 1-877-372-3473.

To Watch a Movie on Battery Power:

1.Have an additional full-charged battery or your AC adapter ready for use.

2.Start watching your DVD movie.

3.When the low battery warning occurs, immediately stop the movie and exit the media player.

C A U T I O N

If you do not stop the media player quickly and the LifeBook notebook attempts to auto-suspend (critical battery low state) the LifeBook notebook will shut down improperly. If this occurs, you will need to perform a hard reset and follow the instruction, if any, presented to you before the system will reboot.

4.Power down your LifeBook notebook and replace the discharged battery with an additional fully- charged battery. If you do not have an additional battery, you may attach AC power as soon as you see the low battery warning.

5.Resume your LifeBook notebook by pressing the Suspend button again. This step is not required if you attached AC power without entering suspend mode.

6.Restart your media player, locate and skip to the chapter of the movie you were last watching.

7.Continue watching your DVD movie.

P O I N T

Some shorter DVD movies may not require you to swap batteries or attach AC power to complete them. However, it is best to be prepared since actual battery life while operating the media player drive cannot be guaranteed.
