Use the following safety guidelines to help protect your computer system from poten-
tial damage and to ensure your own personal safety.
:KHQ8VLQJ<RXU&RPSXWHU6\VWHP
As you use your computer system, observe the following safety guidelines.

To help avoid damaging your computer, be sure the voltage selection switch on
the power supply is set to match the AC power available at your location:
— 115 volts (V)/60 hertz (Hz) in most of North and South America and some Far
Eastern 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 oper-
ate with the AC power available in your location.
Before working inside the computer, unplug the system to help prevent electric
shock or system board damage. Certain system board components continue to
receive power any time the computer is connected to AC power.
To help avoid possible damage to the system board, wait 5 seconds after turning
off the system before disconnecting a 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
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.
To help protect your computer system from sudden, transient increases and
decreases in electrical power, use a surge suppressor, line conditioner, or un-
interruptible 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.

vi
Do not spill food or liquids on your computer. If the computer gets wet, consult
your
Diagnostics and Troubleshooting 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.

For comfort and efficiency, observe the following ergonomic guidelines when setting
up and using your computer system:
Position your system so that the monitor and keyboard are directly in front of you
as you work. Special shelves are available (from Dell and other sources) to help
you correctly position your keyboard.
Set the monitor at a comfortable viewing distance (usually 510 to 610 millimeters
[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.
Adjust the tilt of the monitor, its contrast and brightness settings, and the lighting
around you (such as overhead lights, desk lamps, and the curtains or blinds on
nearby windows) to minimize reflections and glare on the monitor screen.
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 or mouse.
Always leave space to rest your hands while using the keyboard or 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 chair’s 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 of time. When you stop typing, try to do things that
use both hands.

While you work, periodically touch an unpainted metal surface on the computer
chassis to dissipate any static electricity that might harm internal components.

In addition, take 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 dis-
connecting 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 bend-
ing any 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 con-
tacts on a card. Hold a card by its edges or by its metal mounting bracket. Hold a
component such as a microprocessor chip by its edges, not by its pins.
3URWHFWLQJ$JDLQVW(OHFWURVWDWLF'LVFKDUJH
Static electricity can harm delicate 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 the microprocessor. You can do so
by touching an unpainted 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.
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 in your computer. 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.
The following caution may appear throughout this document to remind you of these
precautions:

provides information on connecting the system to a network, configuring the net-
work interface controller (NIC), and installing drivers for the NIC.
Chapter 5, “Working Inside Your Computer,” Chapter 6, “Installing System Board
Options,” and Chapter 7, “Installing Drives,” are intended for users who want to
install or remove options inside the computer, such as dual in-line memory mod-
ules (DIMMs), additional video memory, expansion cards, or drives.
Appendix A, “Technical Specifications,” is intended primarily as reference mate-
rial for users interested in learning more about the details of the system.
Appendix B, “ISA Configuration Utility Messages,” describes error messages
generated by the ISA Configuration Utility (ICU), possible causes, and corrective
actions.

x
Appendix C, “Regulatory Notices,” is for users who are interested in which regu-
latory agencies have tested and approved the Dell OptiPlex E1 Mini Tower
Managed PC.
