Safety and EMC Instructions: Mobile

Workstation Computers

The following information defines the meaning of symbols used in the

Safety and Electromagnetic Compatibility (EMC) Instructions.

Safety Instructions

General

Attention: Caution Risk of electric shock

Risk of explosion Aircraft

Risk of fire Use of this feature may be prohibited

on aircraft

• Do not attempt to service the computer yourself unless

you are an authorized service technician. Always follow

installation instructions closely.

• If you use an extension power cable with your AC

adapter, ensure that the total ampere rating of the

products plugged in to the extension power cable does

not exceed the ampere rating of the extension cable.

• 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.

• Place the AC adapter in a ventilated area, such as a desk

top or on the floor, when you use it to run the computer

or to charge the battery. Do not cover the AC adapter

with papers or other items that will reduce cooling; also,

do not use the AC adapter inside a carrying case.

Dell Precision™ Mobile Workstation M40 System Information 5

• Do not allow your mobile workstation computer to

operate with the base resting directly on exposed skin

for extended periods of time. The surface temperature

of the base will rise during normal operation

(particularly when AC power is present). Allowing

sustained contact with exposed skin can cause

discomfort or, eventually, a burn.

• Do not use your computer in a wet environment, for

example, near a bath tub, sink, or swimming pool or in a

wet basement.

• If your computer includes an integrated or optional (PC

Card) modem, disconnect the modem cable if an

electrical storm is approaching 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. Do not use your computer during

an electrical storm unless all cables have been

disconnected and the computer is operating on battery

power.

• If your computer includes a 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.

• PC Cards may become very warm during normal

operation. Use care when removing PC Cards after their

continuous operation.

• Before you clean your computer, remove power. Clean

your computer with a soft cloth dampened with water.

Do not use liquid or aerosol cleaners, which may

contain flammable substances.

Power (Safety Instructions, continued)

• Use only the Dell-provided AC adapter approved for

use with this computer. Use of another AC adapter may

cause a fire or explosion.

• Before you connect the computer to an electrical outlet,

check the AC adapter voltage rating to ensure that the

required voltage and frequency match the available

power source.

• To remove power from the computer, turn it off,

remove the battery pack, and disconnect the AC

adapter from the electrical outlet.

• To help prevent electric shock, plug the AC adapter and

peripheral power cables into properly grounded power

sources. These power cables may be equipped with

three-prong plugs to provide an earth grounding

connection. Do not use adapter plugs or remove the

grounding prong from the power cable plug. If you use a

power extension cable, use the appropriate type, two-

prong or three-prong, to mate with the AC adapter

power cable.

• Be sure that nothing rests on your AC adapter's power

cable and that the cable is not located where it can be

tripped over or stepped on.

• If you are using a multiple-outlet power strip, use

caution when plugging the AC adapter's power cable

into the power strip. Some power strips may allow you

to insert the plug incorrectly. Incorrect insertion of the

power plug could result in permanent damage to your

computer, as well as risk of electric shock and/or fire.

Ensure that the ground prong of the power plug is

inserted into the mating ground contact of the power

strip.

Dell Precision™ Mobile Workstation M40 System Information 7

Battery (Safety Instructions, continued)

• Use only Dell battery modules that are approved for use

with this computer. Use of other types may increase the

risk of fire or explosion.

• Do not carry a battery pack in your pocket, purse, or

other container where metal objects (such as car keys or

paper clips) could short-circuit the battery terminals.

The resulting excessive current flow can cause

extremely high temperatures and may result in damage

to the battery pack or cause fire or burns.

• The battery poses a burn hazard if you handle it

improperly. Do not disassemble it. Handle a damaged

or leaking battery pack with extreme care. If the battery

is damaged, electrolyte may leak from the cells and may

cause personal injury.

• Keep away from children.

• 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.

When heated to excessive temperatures, battery cells

could explode or vent, posing a risk of fire.

• 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.

Air Travel (Safety Instructions, continued)

EMC Instructions

• 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.

• 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 workstation computer 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

workstation computer, 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.
