Do not attempt to service the computer yourself. Always follow installation
instructions closely.
Do not carry a battery pack in your pocket, purse, or other container where metal
objects (such as car keys) could short-circuit the battery terminals. The resulting
excessive current flow can cause extremely high temperatures and may result in
damage from burns.
Be sure that nothing rests on your adapters power cable and that the cable is not
located where it can be tripped over or stepped on.
Place the AC adapter in a ventilated area, such as a desk top or on the floor, when
powering the computer or charging the battery. Do not cover the AC adapter with
papers or other items that will reduce cooling. Do not use the AC adapter inside a
carrying case.
Do not use your computer in a wet environment, for example, near a bath tub,
sink, or swimming pool or in a wet basement.
Do not push objects into air vents or openings of your computer. Doing so can
cause fire or electric shock by shorting out interior components.
Use only the AC adapter and batteries that are approved for use with this com-
puter as indicated in this document. Use of another type of battery pack or
AC adapter may risk fire or explosion.

Before you connect the computer to a power source, ensure that the voltage rat-
ing of the AC adapter matches that of the available power source:
115 volts (V)/60 hertz (Hz) in most of North and South America and some Far
Eastern countries such as South Korea and Taiwan
100 V/50 Hz in eastern Japan and 100 V/60 Hz in western Japan
230 V/50 Hz in most of Europe, the Middle East, and the Far East
To help prevent electric shock, plug the AC adapter 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.
If you use an extension cable with your AC adapter, ensure that the total
ampere (A) rating of the products plugged into the extension cable does not
exceed the ampere rating of the extension cable.
To remove power from the computer, turn it off, remove the battery pack, and dis-
connect the AC adapter from the electrical outlet.
If your computer includes an integrated or optional (PC Card) modem, the cable
used with the modem should be manufactured with a minimum wire size of 26
American wire gauge (AWG) and an FCC-compliant RJ-11 modular plug.
Disconnect the modem cable during an electrical storm to avoid the remote risk
of electric shock from lightning via the telephone line.
To help avoid the potential hazard of electric shock, do not connect or disconnect
any cables or perform maintenance or reconfiguration of this product during an
electrical storm.
PC Cards may become very warm during normal operation. Use care when
removing PC Cards after their continuous operation.
Do not dispose of battery packs in a fire. They may explode. Check with local
authorities for disposal instructions.
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 com-
puter 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.
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 tem-
perature 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.

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.
Before you clean your computer, turn it off, unplug it from its power source, and
remove the battery pack(s).
Clean your computer with a soft cloth dampened with water rather than with
liquid or aerosol cleaners.
Clean the display with a soft, clean cloth and commercial window cleaner that
does not contain wax or abrasives. Apply the cleaner to the cloth; then stroke the
cloth across the display in one direction, moving from the top of the display to the
bottom. If the display contains grease or some other contaminant, use isopropyl
alcohol instead of commercial window cleaner.
If your computer gets wet or is damaged, follow the procedures described in
Troubleshooting Your Computer in the
Users Guide
. If, after following these
procedures, you confirm that your computer is not operating properly, contact
Dell. (See Getting Help in the
Users Guide
for the appropriate telephone
number.)

For comfort and efficiency, observe the following ergonomic guidelines when setting
up and using your computer:
Position your computer directly in front of you as you work.
Adjust the tilt of the computers display, its contrast and/or brightness settings,
and the lighting around you (such as overhead lights, desk lamps, and the cur-
tains or blinds on nearby windows) to minimize reflections and glare on the
display.
When using an external monitor with your computer, set the monitor at a com-
fortable viewing distance (usually 510 to 610 millimeters [mm] [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.
Use a chair that provides good lower back support.
Keep your forearms horizontal with your wrists in a neutral, comfortable position
while using the keyboard, touch pad or external mouse.
Always use the palmrest with the keyboard or touch pad. Leave space to rest
your hands when using an external mouse.
Let your upper arms hang naturally at your sides.
Sit erect with your feet resting on the floor and your thighs level.
When sitting, make sure the weight of your legs is on your feet and not on the
front of your chair seat. Adjust your chairs height or use a footrest, if necessary,
to maintain proper posture.
Vary your work activities. Try to organize your work so that you do not have to
type for extended periods without stopping. When you stop typing, try to do
things that use both hands.

You can also take the following steps to prevent damage from electrostatic
discharge (ESD):
When unpacking a static-sensitive component from its shipping carton, do not
remove the component from the antistatic packing material until you are ready to
install the component. Just before unwrapping the antistatic packaging, be sure
to discharge static electricity from your body.
When transporting a sensitive component, first place it in an antistatic container
or packaging.
Handle all sensitive components in a static-safe area. If possible, use antistatic
floor pads and workbench pads.

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 navi-
gation or other safety service or seriously degrades, obstructs, or repeatedly
interrupts a licensed radio communications service. Radio communications services
include but are not limited to AM/FM commercial broadcast, television, cellular
services, radar, air-traffic control, pager, and Personal Communication Services (PCS).
These licensed services, along with unintentional radiators such as digital devices,
including computer systems, contribute to the electromagnetic environment.
Electromagnetic Compatibility (EMC) is the ability of items of electronic equipment to
function properly together in the electronic environment. While this computer system
has been designed and determined to be compliant with regulatory agency limits for
EMI, there is no guarantee that interference will not occur in a particular installation. If
this equipment does cause interference with radio communications services, which
can be determined by turning the equipment off and on, you are encouraged to try to
correct the interference by one or more of the following measures:
Reorient the receiving antenna.
Relocate the computer with respect to the receiver.
Move the computer away from the receiver.
Plug the computer into a different outlet so that the computer and the receiver
are on different branch circuits.
If necessary, consult a Technical Support representative of Dell or an experienced
radio/television technician for additional suggestions. You may find the
FCC Interfer-
ence Handbook, 1986
, to be helpful. It is available from the U.S. Government Printing
Office, Washington, DC 20402, Stock No. 004-000-00450-7 or on the World Wide
Web at http://www.fcc.gov/cib/Publications/tvibook.html.

Dell computers are designed, tested, and classified for their intended electromagnetic
environment. These electromagnetic environment classifications generally refer to
the following harmonized definitions:
Class A is for business or industrial environments.
Class B is for residential environments.
Information Technology Equipment (ITE), including peripherals, expansion cards, print-
ers, input/output (I/O) devices, monitors, and so on, that are integrated into or
connected to the system should match the electromagnetic environment classifica-
tion of the computer system.

Most Dell computer systems are classified for Class B environments. To determine
the electromagnetic classification for your system or device, refer to the following
sections specific for each regulatory agency. Each section provides country-specific
EMC/EMI or product safety information.

Most Dell computer systems are classified by the Federal Communications
Commission (FCC) as Class B digital devices. However, the inclusion of certain
options can change the rating of some configurations to Class A. To determine which
classification applies to your computer system, examine all FCC registration labels
located on the bottom or back panel of your computer, on card-mounting brackets, and
on the cards themselves. If any one of the labels carries a Class A rating, your entire
system is considered to be a Class A digital device. If
all
labels carry an
FCC Class B rating as distinguished by either an FCC ID number or the FCC logo,
( ), your system is considered to be a Class B digital device.
Once you have determined your systems FCC classification, read the appropriate
FCC notice. Note that FCC regulations provide that changes or modifications not
expressly approved by Dell could void your authority to operate this equipment.
This device complies with Part 15 of the FCC Rules. Operation is subject to the follow-
ing two conditions:
This device may not cause harmful interference.
This device must accept any interference received, including interference that
may cause undesired operation.

This equipment complies with Part 68 of the FCC rules. On the bottom of your com-
puter is a label that contains, among other information, the FCC registration number
and ringer equivalence number (REN) for your equipment. If requested, you must pro-
vide this information to the telephone company.
The REN is used to determine the quantity of devices that may be connected to the
telephone line. Excessive RENs on the telephone line may result in the devices not
ringing in response to an incoming call. In most areas, the sum of all the RENs on your
telephone line should be less than five to ensure proper service from the telephone
company. To be certain of the number of devices that you may connect to a line, as
determined by the total RENs, contact your local telephone company.
The registration jack Universal Service Order Code (USOC) used by this equipment is
RJ-11C. An FCC compliant telephone cord and modular plug is provided with this
equipment. This equipment is designed to be connected to the telephone network or
premises wiring using a compatible modular jack that is Part 68 compliant.
This equipment cannot be used on public coin-phone service provided by the tele-
phone company. Connection to party line service is subject to state tariffs.
There are no user serviceable parts on the modem contained in your computer.
If your telephone equipment causes harm to the telephone network, the telephone
company will notify you in advance that service may be temporarily discontinued. If
advance notice is not practical, the telephone company will notify you as soon as pos-
sible. Also, you will be advised of your right to file a complaint with the FCC if you
believe it is necessary.
The telephone company may make changes in its facilities, equipment, operations, or
procedures that could affect the operation of this equipment. If this happens, the tele-
phone company will provide advance notice in order for you to make necessary
modifications to maintain uninterrupted service.
If you experience trouble with this telephone equipment, refer to the chapter titled
"Getting Help" in your system's troubleshooting documentation or, for some systems,
the section titled "Contacting Dell" in your system's online guide to find the appropri-
ate telephone number for obtaining customer assistance. If the equipment is causing
harm to the telephone network, the telephone company may request that you discon-
nect the equipment until the problem is resolved.

The Telephone Consumer Protection Act of 1991 makes it unlawful for any person to
use a computer or other electronic device, including fax machines, to send any mes-
sage unless such message clearly contains in a margin at the top or bottom of each
transmitted page or on the first page of the transmission, the date and time it is sent,
identification of the business, other entity, or individual sending the message, and the
telephone number of the sending machine or such business, other entity, or individ-
ual. The telephone number provided may not be a 900 number or any other number
for which charges exceed local or long-distance transmission charges.

The IC label identifies certified equipment. This certification means that the equip-
ment meets telecommunications network protective, operational, and safety
requirements as prescribed in the appropriate Terminal Equipment Technical Require-
ments document(s). The IC label does not guarantee that the equipment will operate
to the user's satisfaction.
Before installing this equipment, users should ensure that it is permissible to be con-
nected to the facilities of the local telecommunications company. The equipment
must also be installed using an acceptable method of connection. The customer
should be aware that compliance with the above conditions may not prevent degrada-
tion of service in some situations.
Repairs to certified equipment should be coordinated by a representative designated
by the supplier. Any repairs or alteration made by a user to this equipment, or equip-
ment malfunctions, may give the telephone communications company cause to
request the user to disconnect the equipment.
Users should ensure for their own protection, that the electrical ground connections
of the power utility, telephone lines, and internal metallic water-pipe system, if
present, are connected together. This precaution may be particularly important in rural
areas.
