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 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 accidentally dislodged.
Connecting cables
Read the following before connecting cables:
• Connect all device cables before plugging any power cords into an electrical
outlet.
• Connect the power cords to the computer and to the other devices before
plugging them into an electrical outlet.
If your computer is being connected to an Ethernet network, a Category 5
Ethernet cable must be used for operation of the system within FCC Class
A limits.
