Use shielded signal cables to ensure that you maintain the appropriate EMC classification for the
intended environment. For parallel printers, a cable is available from Dell. If you prefer, you can order a
cable from Dell at its world-wide website at http://www.dell.com.
Static electricity can harm electronic components inside your computer. To prevent static damage,
discharge static electricity from your body before you touch any of your computer's electronic
components, such as a memory module. You can do so by touching an unpainted metal surface on the
computer's input/output panel.
When Using Your Computer
Observe the following guidelines to prevent damage to your computer.
When setting up the computer for work, place it on a level surface.
When traveling, do not check the computer as baggage. You can put your computer through an X-ray
security machine, but never put your computer through a metal detector. If you have the computer
checked by hand, be sure to have a charged battery available in case you are asked to turn on the
When traveling with the hard-disk drive removed from the computer, wrap the drive in a nonconducting
material, such as cloth or paper. If you have the drive checked by hand, be ready to install the drive in
the computer. You can put the hard-disk drive through an X-ray security machine, but never put the
drive through a metal detector.
When traveling, do not place the computer in overhead storage compartments where it could slide
around. Do not drop your computer or subject it to other mechanical shocks.
Protect your computer, battery, and hard-disk drive from environmental hazards such as dirt, dust,
food, liquids, temperature extremes, and overexposure to sunlight.
When you move your computer between environments with very different temperature and/or humidity
ranges, condensation may form on or within the computer. To avoid damaging the computer, allow
sufficient time for the moisture to evaporate before using the computer.
NOTICE: When taking the computer from low-temperature conditions into a
warmer environment or from high-temperature conditions into a cooler
environment, allow the computer to acclimate to room temperature before
turning on power.
When you disconnect a cable, pull on its connector or on its strain-relief loop, not on the cable itself. As
you pull out the connector, keep it evenly aligned to avoid bending any connector pins. Also, before you
connect a cable make sure both connectors are correctly oriented and aligned.
Handle components with care. Hold a component such as a memory module by its edges, not its pins.
When removing a memory module from the system board or disconnecting a peripheral device from the
computer, wait 5 seconds after turning off the computer before removing the memory module or
