EMC Instructions
l 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.
l 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.
l
When setting up the computer for work, place it on a level surface.
l
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 computer.
l
When traveling with the hard 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 drive through an X-ray security machine, but
never put the drive through a metal detector.
l 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.
l
Protect your computer, battery, and hard drive from environmental hazards such as dirt, dust, food, liquids, temperature extremes, and
overexposure to sunlight.
l 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.
l 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.
l Handle components with care. Hold a component such as a memory module by its edges, not its pins.
l
When removing a memory module from the system board or disconnecting a peripheral device from the computer, wait 5 seconds after
l Do not store or leave your computer or battery pack near a heat source such as a radiator, fireplace, stove, electric heater, or
other heat-
generating appliance or otherwise expose it to temperatures in excess of 60°C (140°F). When heated to
excessive temperatures, battery cells could explode or vent, posing a risk of fire.
l
Do not dispose of your computer's battery in a fire or with normal household waste. Battery cells may explode. Discard a
used battery according to the manufacturer's instructions or contact your local waste disposal agency for disposal
instructions. Dispose of a spent or damaged battery promptly.
l Certain Federal Aviation Administration regulations and/or airline-specific restrictions may apply to the operation of your Dell
computer while you are onboard an aircraft. For example, such regulations/restrictions may prohibit the use of any personal
electronic device (PED) that has the capacity for intentional transmission of radio frequency or other electromagnetic signals while
on an aircraft.
¡ In order to best comply with all such restrictions, if your Dell mobile workstationcomputer is equipped with Dell
TrueMobile™ or some other wireless communication device, please disable this device before you board the aircraft
and follow all instructions provided by airline personnel with regard to such device.
¡ Additionally, the use of any PED, such as a mobile workstationcomputer, may be prohibited in aircraft during certain
critical phases of flight, for example, takeoff and landing. Some airlines may further define the critical flight phase as any
time the aircraft is below 3050 m (10,000 ft). Please follow the airline's specific instructions as to when the use of a PED
is allowed.
