70 - Troubleshooting
Possible Solutions
Adjust the volume control on your notebook and operating system. Use the
[Fn+F9] key combination on your keyboard. Pressing [F9] repeatedly while hold-
ing [Fn] will increase the volume of your notebook.
Manually adjusting the volume (using the keyboard hot keys) should dynamically
adjust the volume (see above). If that doesn't work, adjust the sound volume con-
trol settings in your software or application.
Plugging in headphones disables the built-in speakers. Remove the headphones.
The Audio Driver may be installed or reinstalled by using the Fujitsu Software
Download Manager (FSDM). Refer to "Downloading Driver Updates" on page 86.
Click on the Volume icon in the tool tray on the bottom right of the screen. (It
looks like a speaker). If the Mute box is checked, click on it to uncheck it. Pressing
the [F3] key while holding the [Fn] key will also toggle the audio on and off.
Open optical drive tray and re-install the disc properly.
Install DVD Player software.
Verify that the drive designator used by the application is the same as used by the
operating system. When the OS is booted from a DVD/CD, drive designators are
automatically adjusted.
Wipe the disc with a non-abrasive CD cleaning cloth and reinsert. It if still will not
work try another disc in the drive.
Install DVD player software.
Select the DVD player software from the programs list and right-click on the win-
dow. Select Properties and verify that the region selected is "USA, Canada."
