Power (Safety Instructions, continued)
• Place the AC adapter in a ventilated area, such as a desk
top or on the floor, when you use it 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.
• Do not allow your portable 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.
• 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.
• Use only the Dell-provided AC adapter approved for
use with the high-capacity battery pack. Use of another
AC adapter may cause a fire or explosion.
• Before you connect the high-capacity battery pack to an
electrical outlet, check the AC adapter voltage rating to
ensure that the required voltage and frequency match
the available power source.
2H934bk0.book Page 4 Wednesday, October 10, 2001 11:08 AM

Dell™ Latitude™ C400 High-Capacity Battery Pack 5
Battery (Safety Instructions, continued)
• To help prevent electric shock, plug the AC adapter
cable into a properly grounded power source. The
power cable may be equipped with a three-prong plug
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 the AC adapter 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 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.
• Do not carry the high-capacity battery pack in your
luggage, briefcase, 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 high-capacity battery pack 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 pack is damaged, electrolyte may leak from
the cells and may cause personal injury.
• Keep away from children.

• Protect your high-capacity battery pack from environmental hazards
such as dirt, dust, food, liquids, temperature extremes, and
overexposure to sunlight.
• When you move the high-capacity battery pack between environments
with very different temperature and/or humidity ranges, condensation
may form on or within the high-capacity battery pack. To avoid
damage, allow sufficient time for the moisture to evaporate before
using the battery pack.
NOTICE: When taking the high-capacity battery pack from low-temperature
conditions into a warmer environment or from high-temperature conditions
into a cooler environment, allow the battery pack to acclimate to room
temperature before turning on power.
• 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.
• 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, or
otherwise expose it to temperatures in excess of 60°C
(140°F). When heated to excessive temperatures,
battery cells could explode or vent, posing a risk of fire.
• Do not dispose of a high-capacity battery pack in a fire
or with normal household waste. Battery cells may
explode. Discard a used battery pack according to the
manufacturer’s instructions or contact your local waste
disposal agency for disposal instructions. Dispose of a
spent or damaged battery pack promptly.
