About the Speakers
Why is there no sound in any application?
 Adjust the volume control dial, located on the left panel, to adjust speaker volume.
 If the software application you are using has its own volume control, check that the volume is turned up.
 Check the volume controls in the Windows ® operating system using these steps:
1. Click Start in the Windows taskbar, then select Control Panel.
2. Select Sounds, Speech, and Audio Devices, then click Adjust the system volume. The Sounds and Audio
Devices Properties dialog box appears.
3. From the Volume tab, adjust the Device volume by moving the slider bar to the desired sound level. Verify
that the Mute option is not enabled.
 Check that the Mute check box is not selected in the Windows volume control.
You may need to reinstall the sound drivers. See Reinstalling device drivers using Application Recovery CD(s) for more
information.
How can I use headphones while my speakers are connected?
The speakers continue to produce sound even when headphones have been connected. If you want to use optional
headphones instead of the supplied speakers, adjust the volume control dial, located on the left panel, to mute the built-in
stereo speakers.
