The Dell Latitude LS Advanced Port Replicator (APR) integrates your Dell Latitude LS
portable computer quickly and easily into a desktop environment. Use the instructions
in this document to attach external devices to the APR and to connect your computer
to the APR.
NOTE: If you received a basic input/output system (BIOS) upgrade diskette with your
APR, use the diskette to upgrade the BIOS on your Dell Latitude LS computer before
attaching the computer to the APR. For instructions, see the documentation that
came with the BIOS upgrade diskette.

Use the following safety guidelines to help protect your APR from potential damage
and to help ensure your own personal safety:
Do not attempt to service the APR yourself. Always follow installation instruc-
tions closely.
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.
Place the AC adapter in a ventilated area, such as a desktop or on the floor, when
powering the APR. 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 APR in a wet environment, for example, near a bathtub, sink, or
swimming pool or in a wet basement.
Do not push objects into air vents or openings of your APR. Doing so can cause
fire or electric shock by shorting out interior components.
Use only the AC adapter that is approved for use with this APR as indicated in
this document. Use of another type of AC adapter may risk fire or explosion.
Before you connect the APR 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
rating of the products plugged into the extension cable does not exceed the
ampere rating of the extension cable.
To remove power from the APR, turn off the computer 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.
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.
When setting up the APR for work, place it on a level surface.
Protect your APR from environmental hazards such as dirt, dust, food, liquids,
temperature extremes, and overexposure to sunlight.
When you move your APR between environments with very different tempera-
ture or humidity ranges, condensation may form on or within the computer. To
avoid damaging the APR, 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 the APR with care.
Before you clean your APR, turn it off and unplug it from its power source.
Clean your APR with a soft cloth dampened with water rather than with liquid or
aerosol cleaners.

If your APR or computer gets wet or is damaged, follow the procedures
described in “Troubleshooting Your Computer,”in the User’s Guide. If, after fol-
lowing these procedures, you confirm that your APR or computer is not operating

1. Refer to Figure 1-1 to attach external devices to the appropriate connectors on the
back of the APR.
NOTES: If the cable connector from the external device has thumbscrews, be
sure to tighten them to ensure a proper connection.

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 ser-
vices, 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 Regulatory EMC 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/Bureaus/Compliance/WWW/tvibook.html.
Dell computer systems are designed, tested, and classified for their intended electro-
magnetic 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.
