Where it is impossible to avoid reflections or to adjust the lighting, an antiglare filter placed over the screen might be helpful. 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 as directed in your monitor documentation. 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 inches) of air space is sufficient. Also, make sure the vented air is not blowing on people. Electrical outlets and cable lengths The location of electrical outlets, 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: v Avoid the use of extension cords. When possible, plug the computer power cord directly into an electrical outlet. v Keep power cords and cables neatly routed away from walkways and other areas where they might get kicked accidentally. For more information about power cords, refer to the ThinkStation Safety and Warranty Guide that came with your computer. 4 User Guide
