Plugs and outlets

If a receptacle (power outlet) that you intend to use with your computer equipment
appears to be damaged or corroded, do not use the outlet until it has been replaced by
a qualified electrician.
Do not bend or modify any plug. If a plug is damaged, contact the relevant
manufacturer to obtain a replacement.
Some products are equipped with a three-pronged plug. This kind of plug fits only
into a grounded electrical outlet. This is a safety feature. Do not defeat this safety
feature by trying to insert the plug into a non-grounded outlet. If you cannot insert the
plug into an outlet, contact a qualified electrician for details on obtaining an approved
outlet adapter, or to have the outlet replaced with one that enables this safety feature.
Never overload an electrical outlet. The overall system load should not exceed 80
percent of the branch circuit rating. If you have any questions about power loads or
branch circuit ratings, consult a qualified electrician.
Be sure that the power outlet you are using is properly wired, easily accessible and
located close to the equipment. Do not fully extend power cords in a way that will
stress the cords.
Connect and disconnect equipment from electrical outlets carefully.

Heat and product ventilation

Computers, AC power adapters and various accessories generate heat during use, as
do batteries while being charged. Always follow the basic precautions below:
• Do not leave a computer, AC power adapter or accessory in contact with the body
for extended periods of use, or while the battery is charging. Computers, AC power
adapters and accessories generate heat during normal operation; contact with the
body for extended periods can cause discomfort or, potentially, a skin burn.
• Do not charge a battery or operate your computer, AC power adapter or accessories
near flammable materials or in explosive environments.
• This product includes ventilation slots, fans and heat sinks for safe and reliable
operation. These safety features may be compromised if the product is placed on a
bed, sofa, carpet or other soft surface. Never block, cover or disable these safety
features.
