Glare And Lighting; Air Circulation; Electrical Outlets And Cable Lengths - IBM Aptiva E 2270 User Manual

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 58.
