Overview
Use the following safety guidelines to help protect your computer system from potential damage and to ensure your own
personal safety.
WARNING: There is a danger of a new battery exploding if it is incorrectly installed. Replace the battery
only with the same or equivalent type recommended by the manufacturer. Discard used batteries
according to the manufacturer's instructions.
When Using Your Computer System
As you use your computer system, observe the following safety guidelines:
Be sure your monitor and attached peripherals are electrically rated to operate with the AC power available in
your location.
To help prevent electric shock, plug the computer and peripheral power cables into properly grounded power
sources. These cables are equipped with three-prong plugs to help ensure proper grounding. Do not use adapter
plugs or remove the grounding prong from a cable. If you must use an extension cable, use a three-wire cable
with properly grounded plugs.
To help protect your computer system from sudden, transient increases and decreases in electrical power, use a
surge suppressor, line conditioner, or uninterruptible power supply (UPS).
Be sure nothing rests on your computer system's cables and that the cables are not located where they can be
stepped on or tripped over.
Do not spill food or liquids on your computer.
Do not push any objects into the openings of your computer. Doing so can cause fire or electric shock by shorting
out interior components.
Keep your computer away from radiators and heat sources. Also, do not block cooling vents. Avoid placing loose
papers underneath your computer; do not place your computer in a closed-in wall unit or on a rug.
Ergonomic Computing Habits
WARNING: Improper or prolonged keyboard use may result in injury.
For comfort and efficiency, observe the following ergonomic guidelines when setting up and using your computer
system:
Position your system so that the monitor and keyboard are directly in front of you as you work. Special shelves
are available (from Dell and other sources) to help you correctly position your keyboard.
Set the monitor at a comfortable viewing distance (usually 510 to 610 millimeters [20 to 24 inches] from your
eyes).
Make sure the monitor screen is at eye level or slightly lower when you are sitting in front of the monitor.
