Use the following safety guidelines to ensure your own personal safety and to help protect your system from potential
damage.
Safety Cautions
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 may 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 the 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 a fire or an 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.
