Safety Instructions

Use the following safety guidelines to ensure your own personal safety and to help protect
your system from potential damage.

To reduce the risk of bodily injury, electrical shock, fire, and damage to the equipment,
observe the following precautions:

• Observe and follow service markings.

- Do not service any product except as explained in your system documentation.

- Opening or removing covers that are marked with the triangular symbol with a

lightning bolt can expose you to electrical shock. Only a trained service technician
should service components inside these compartments.

• If any of the following conditions occur, unplug the product from the electrical outlet and

replace the part, or contact your trained 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 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 system gets wet, contact technical support or your trained
service provider.

• Do not push any objects into the openings of your system. Doing so can cause fire or

electric shock by shorting out interior components.

• Use the product only with approved equipment.

• Allow the product to cool before removing covers or touching internal components.

• Operate the product only from the type of external power source indicated on the

electrical ratings label. If you are not sure of the type of power source required, consult
your service provider or local power company.

• To help avoid damaging your system, be sure that 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

- 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

• Also, be sure that attached devices are electrically rated to operate with the power

available in your location.

• Use only approved power cables. If you have not been provided with a power cable for

your system or for any AC-powered option intended for your system, purchase a power
