Observe the following general precautions for using and working with your system:
Observe and follow service markings. Do not service any Dell product except as
explained in your Dell system documentation. Opening or removing covers that
are marked with the triangular symbol with a lightning bolt may expose you to
electrical shock. Components inside these compartments should be serviced
only by a Dell authorized service technician.
If any of the following conditions occur, unplug the product from the electrical
outlet and replace the part or contact your Dell authorized service provider:
The power cable, extension cable, or plug is damaged.
An object has fallen into the product.
The product has been exposed to water.
The product has been dropped or damaged.
The product does not operate correctly when you follow the operating
instructions.
Keep your system components away from radiators and heat sources. Also, do
not block cooling vents.
Do not spill food or liquids on your system components, and never operate the
product in a wet environment. If the computer gets wet, see the appropriate
chapter in your troubleshooting guide or contact a Dell-authorized service
provider.
Do not push any objects into the openings of your system components. Doing so
can cause fire or electric shock by shorting out interior components.
Use the product only with Dell products or other Dell-approved equipment.
Allow the product to cool before removing covers or touching internal
components.
Use the correct external power source. Operate the product only from the type
of power source indicated on the electrical ratings label. If you are not sure of the
type of power source required, consult your Dell service provider or local power
company.
To help avoid damaging your system components, be sure the voltage selection
switch (if provided) on the power supply is set to match the 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 South Korea and Taiwan
