Using Your Computer Safely
To avoid possible injury to yourself or damage to your computer, do not install or remove any component, or alter switch or jumper settings, while your computer is on. If you install a modem, disconnect its phone cord every time you remove the computer cover.
To avoid accidental discharge of static electricity, which could damage computer components, you can use a grounding wrist strap.
As you set up and use the computer, take the following precautions:
∙The monitor screen should be at eye level as you sit at the computer. Adjust lighting in the room to reduce glare on the screen. Use the controls on the monitor to adjust the brightness and contrast to comfortable levels.
∙If you plan to use the keyboard or mouse for several hours at a time, consider purchasing and using wrist- support padding. Take occasional breaks from using the computer.
∙Use a flat, stable work surface with enough space around it for proper air circulation. These are the minimum clearances:
Rear of system: 3 in (7.6 cm)
Left side of system: 6 in (15.2 cm)
Right side of system: 6 in (15.2 cm)
Top of monitor: 6 in (15.2 cm)
∙Use the system in an environment where the air temperature is more than 41 F °(5° C) and less than 104° F (40° C). For nonoperating systems, such as systems in storage, the acceptable temperature range is
∙Choose a work surface large enough to accommodate the entire system.
∙Protect the equipment from wet weather and liquids.
∙Avoid dropping, jarring, or shaking the equipment.
