Safety Instructions
se the foll owing safety guidelines to help pr otect
U
your computer’ s system from potentia l damage and to
ensure your own personal safety.
W
hen Using Your Computer System
As you use your computer syste m, observe the foll owing
safety gu idelin es:
To help avoid damaging your c omputer, be sure the
•
voltage s elec tion s wit ch on t he power s uppl y is set to
match t h e alternating current (AC) power available
at your location:
— 115 volts (V)/6 0 hertz (Hz) in mo st of North and
South America and some Far Eas tern countries
such as Japan, South Korea, and Taiwan
— 230 V/50 Hz in most of Europe, the Middle
East, and the Far East
Also be sure your monitor and attached peripherals
are electrically rated to operate with the AC power
available in your location.
To help avoid possi ble damage to the system board,
•
wait five seconds aft er turning off the system befo re
removing a component from the system board or disconnecting a peripheral device from the computer.
To help prevent electric shock, plug the computer
•
and peripheral power cables into properly grounded
power sources. These cables are equipped with 3prong plugs to en su re proper grounding. Do not use
adapter plu gs or remove the grounding prong from a
cable. If you must use an extension cable, use a 3wire cable with properly grounded plugs.
To help protect your comput er s ys tem from sudden,
•
tran sient in creases and decreases in ele ctrical power,
use a surge suppressor, line conditioner, or uninterruptible power supply.
Be sure nothing rests on your c omputer system’s
•
cables an d that the cables are not lo cated 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
Troublesh ooting 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 cl osed-in wall unit or
on a bed, sofa, or rug.
Diagnostics and
Ergonomic Computing Habits
WARNING: Improper or prolonged keyboard use
may result in injury.
For comfort and efficiency, observe the following ergonomic guidelines when s etting up and using your
computer syste m:
Position your system so that the monitor and key-
•
board are directly in front of you as you work.
Special shelves are available (from Dell and oth er
sources) to help you cor r ectly position your
keyboard.
Set the monitor at a comfortable viewing distanc e
•

from your eyes).
Make s u re th e mo nitor sc re en is at eye leve l or
•
slightly lower when you are sitting in front of the
monitor.
v
Adjust the til t of the monitor, its contrast and bright-
•
ness settings, and the lighting around you (such as
overhead light s, desk lamps, and the curta ins or
blinds on nearb y windows ) to mi nimize reflections
and glare on the monitor screen.
Use a chair that provides good lower back support.
•
Keep your forearms horizon tal with your wrists in a

W
hen Working Inside Your Computer
Before you remove the compute r cover, perform the following steps in the sequence indicated:
CAUTIONS: Do not attempt to service the
computer system yourself, except as explained in
this guide and elsewhere in Dell documentation.
Always follow installation and servicing
instru c t io n s cl o s el y.
To help avoid p ossible damage to the system board,
wait five seconds after turning off the system
before removing a component from the system
board or disconnecting a peripheral device from
the comp u ter.
1.Turn off your computer and any peripheral s.
2.Disconnect your computer and peripherals from
their power sources. Also disconnect any telephone or telecommunication lines from the computer.
Doing so reduces the po tential for personal injury or
shock.
3.Touch an unpainted m e tal s urface on the cha ssis,
such as the metal around the card-slot openings at
the back of the computer, before touching anything inside your computer.
While you work, periodically touch an unpainted
metal s u rfa c e on th e co mp u ter chassis to dis si p ate
any static ele ctricity tha t mi ght harm internal
components.
In addition, ta ke note of these safety guidelines when
appropriate:
When you disconnect a cable, pull on its connector
•
or on its strain-relief loop, not on the cable itself.
Some cables have a connector with locking tabs; if
you are disconnecting this type of cable, press in on
the locking tabs before disconnecting the cable. As
you pull connectors apart, keep them evenly aligned
to avoid bending an y connector pins. Also, before
you connect a cable, make sure both connectors are
correctly oriented and aligned.
Handle components and cards with care. Don’t
•
touch the components or contacts on a card. Hold a
card by its edges or by its metal mounting bracke t.
Hold a comp o n ent such as a microprocessor chip by
its edges, not by its pins.
Protecting Against Electrostatic
Discharge
Static electricity can harm delicate components inside
your computer. T o prevent static damage , discharge
static electricity from your body before you touch any of
your computer’ s electronic components , such as the
microprocessor. You can do so by touc hing an unpain ted
metal surface on the computer chassis.
As you continue to work inside the computer, periodically touch an unpainted metal surface to remove any
static charge your body may have accumulated.
In addition to the preceding precautions, you can also
take the followin g steps to prevent damage from electrostatic discharge (ESD):
When unpacking a stati c-sensitive component from
•
its shipping carton, do not remove the component’s
antistatic packing material until you are ready to
install the component in your computer. Just before
unwrapping the antistatic packaging, be sure to discharge static el ec tricity from your body.
When transportin g a sens itive compone nt, firs t place
•
it in an an ti s t at ic contai n er or packag in g .
Handle all sensi tive c omponen ts in a sta tic-s afe ar ea.
•
If possible, use antistatic floor pads and workbench
pads.
The following caution may appear throughout this document to remind you of these precautions:
CAUTION: See “Protecting Against Electrostatic
Discharge” in the safety instructions at the front of
this guide.
