– 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 cable that is
approved for use in your country. The power cable must be rated for the product and for the
voltage and current marked on the product’s electrical ratings label. The voltage and current
rating of the cable should be greater than the ratings marked on the product.
• To help prevent electric shock, plug the system and peripheral power cables into properly
grounded electrical outlets.
• The peripheral power 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.
• Observe extension cable and power strip ratings. Make sure that the total ampere rating of all
products plugged into the extension cable or power strip does not exceed 80 percent of the
ampere ratings limit for the extension cable or power strip.
