You can connect speakers, a microphone, headphones, and record/playback devices such as cassette players, CD players, and VCRs to the sound jacks on the

computer. Dell recommends using amplified speakers for the best sound.

Connect headphones or speakers to the line-out jack on the far right of the sound jacks. Connect a microphone to the microphone jack in the middle. Connect

record/playback devices such as cassette players, CD players, and VCRs to the line-in jack on the far left.

See your Microsoft®Windows®98 documentation for the location of sound applications such as mixers and volume control.

You can control the sound coming from the external speakers and from the computer's built-in speakers with the volume control dial. You can also use the keyboard to

adjust the volumes. Press <Fn><Page Down> to lower the volume. Press <Fn><Page Up> to increase the volume. Press <Fn><End> to enable or disable both the

built-in and external speakers.

See Reinstalling Utilities and Drivers for information about reinstalling the audio drivers. The drivers are located on the Dell Inspiron 7000 System Software CD.
