review the Safety and Regulatory Guide that came with your workstation for more information.

electrical

Å
WARNING: For your safety always connect the equipment to a grounded floor outlet. Always use a
power cord with a properly grounded plug, such as the one provided with the equipment, or one in
compliance with your national safety standards. This equipment can be disconnected from the power by
removing the power cord from the power outlet. This means the equipment must be located close to an
easily accessible power outlet.

multimedia models

Å
WARNING: If your system is a multimedia model, or if you have installed a sound card in your system,
always turn the volume down before connecting the headphones or speakers. This prevents discomfort
from unexpected noise or static. Listening to loud sounds for prolonged periods of time may permanently
damage your hearing. Before putting on headphones, place them around your neck and turn the volume
down. When you put on the headphones, slowly increase the volume until you find a comfortable
listening level. When you can hear comfortably and clearly, without distortion, leave the volume in that
position.
