enter

and ensure that the Serial Port #1 setting (or the Serial Port #2 settings if you have an
optional serial port adapter installed) or the LPT Port Mode setting matches the recommended settings.
RUN THE DELL DIAGNOSTICS
CHECK THE SPEAKER CABLE CONNECTIONS — Ensure that the speakers are connected as shown on the
setup diagram supplied with the speakers. If you purchased an audio card, ensure that the speakers are
connected to the card.
ENSURE THAT THE SUBWOOFER AND THE SPEAKERS ARE TURNED ON — See the setup diagram supplied
with the speakers. If your speakers have volume controls, adjust the volume, bass, or treble to eliminate
distortion.
ADJUST THE WINDOWS VOLUME CONTROL — Click or double-click the speaker icon in the lower-right
corner of your screen. Ensure that the volume is turned up and that the sound is not muted.
DISCONNECT HEADPHONES FROM THE HEADPHONE CONNECTOR — Sound from the speakers is
automatically disabled when headphones are connected to the computer’s front-panel headphone connector.
TEST THE ELECTRICAL OUTLET — Ensure that the electrical outlet is working by testing it with another
device, such as a lamp.
