• 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. If the computer gets
wet, consult your User’s Guide.
• 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
bed, sofa, or rug.
Ergonomic Computing Habits
CAUTION: Improper or prolonged keyboard use may result in
injury.
CAUTION: Viewing the monitor screen for extended periods of
time may result in eye strain.
For comfort and efficiency, observe the ergonomic guidelines in your
User’s Guide when setting up and using your computer system.
Regulatory Information
Electromagnetic Interference (EMI) is any signal or emission, radiated in
free space or conducted along power or signal leads, that endangers the
functioning of a radio navigation or other safety service or seriously
degrades, obstructs, or repeatedly interrupts a licensed radio
communications service.
Your Dell computer system is designed to comply with applicable
regulations regarding EMI. Changes or modifications not expressly
approved by Dell could void the user’s authority to operate the equipment.
NOTE: Additional regulatory information regarding your system can be found
in your User’s Guide.
