- An object fell into the product.
- The product was exposed to water.
- The product was 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, see the appropriate section in your
troubleshooting guide, or contact 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 avoid damaging your system, be sure that the voltage selection switch (if provided) on
the power supply is set to match the power at your location:
- 115V, 60 Hz in most of North and South America and some Far Eastern countries
such as South Korea and Taiwan
- 100V, 50 Hz in eastern Japan and 100V, 60 Hz in western Japan
- 230V, 50 Hz in most of Europe, the Middle East, and the Far East
• Be sure that attached devices are electrically rated to operate with the power available in
your location.
• Use only approved power cables. If you were not provided with a power cable for your
system or for any AC-powered option intended for your system, purchase a power cable
approved for your country. The power cable must be rated for the product and for the
voltage and current marked on the product electrical ratings label. The voltage and
current rating of the cable must 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.
• To help protect your system from sudden, transient increases and decreases in electrical
power, use a surge suppressor, line conditioner, or uninterruptible power supply (UPS).
• Position system cables and power cables carefully. Route cables so that they cannot be
stepped on or tripped over. Be sure that nothing rests on any cables.
