2-2 Dell Latitude LS Portable Computers System Information
•
Use only the AC adapter and batteries that are approved for use with this
computer 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
rating 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
disconnect 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.
•
If your computer includes an integrated or optional (PC Card) modem, 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
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.
•
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.
