Glare and Lighting Position the monitor to minimize glare and reflections from overhead lights, windows, and other light sources. Place the monitor at right angles to windows and other light sources whenever possible. Reduce overhead lighting, if necessary, by turning off lights or using lower wattage bulbs. If you install the monitor near a window, use curtains or blinds to block the sunlight. You might have to adjust the Brightness and Contrast controls on the monitor as the room lighting changes throughout the day. Where it is impossible to avoid reflections or to adjust the lighting, place an antiglare filter over the screen. However, these filters might affect the clarity of the image on the screen; try them only after you have exhausted other methods of reducing glare. Dust buildup compounds problems associated with glare. Remember to clean your monitor screen periodically using a soft cloth moistened with a nonabrasive liquid glass cleaner. Air Circulation Your computer and monitor produce heat. The computer has a fan that pulls in fresh air and forces out hot air. The monitor lets hot air escape through vents. Blocking the air vents can cause overheating, which might result in a malfunction or damage. Place the computer and monitor so that nothing blocks the air vents; usually, 51 mm (2 in.) of air space is sufficient. Also, make sure the vented air is not blowing on someone else. Electrical Outlets and Cable Lengths The location of electrical outlets and the length of power cords and cables that connect to the monitor, printer, and other devices might determine the final placement of your computer. When arranging your workspace: Avoid the use of extension cords. Whenever possible, plug the computer power cord directly into an electrical outlet. Keep power cords and cables neatly routed away from walkways and other areas where they might be kicked accidentally. For more information about power cords, see "Power Cord Notice" on page 150. 16 PC 300GL User Guide

Electrical Outlets and Cable Lengths
The location of electrical outlets and the length of power cords and cables
that connect to the monitor, printer, and other devices might determine the
final placement of your computer.
When arranging your workspace:
±
Avoid the use of extension cords.
Whenever possible, plug the
computer power cord directly into an electrical outlet.
±
Keep power cords and cables neatly routed away from walkways and
other areas where they might be kicked accidentally.
