Safety and General Information Guide V1.0_en.book Page 8 Friday, March 4, 2011 4:55 PM Chapter 1. Important safety information • When the AC adapter is connected to an electrical outlet and your computer, it generates heat. Do not place the adapter in contact with any part of your body while using it. Never use the AC adapter to warm your body. Extended contact with your body, even through clothing, may cause a skin burn. For your safety, always follow these basic precautions with your computer: • Keep the cover closed whenever the computer is plugged in. • Regularly inspect the outside of the computer for dust accumulation. • Remove dust from vents and any perforations in the bezel. More frequent cleanings might be required for computers in dusty or high-traffic areas. • Do not restrict or block any ventilation openings. • Do not operate your computer inside furniture, as this might increase the risk of overheating. • Airflow temperatures into the computer should not exceed 35°C (95°F). „ CD and DVD drive safety CD and DVD drives spin discs at a high speed. If a CD or DVD is cracked or otherwise physically damaged, it is possible for the disc to break apart or even shatter when the CD drive is in use. To protect against possible injury due to this situation, and to reduce the risk of damage to your computer, do the following: • Always store CD/DVD discs in their original packaging. • Always store CD/DVD discs out of direct sunlight and away from direct heat sources. • Remove CD/DVD discs from the computer when not in use. • Do not bend or flex CD/DVD discs, or force them into the computer or their packaging. • Check CD/DVD discs for cracks before each use. Do not use cracked or damaged discs. 8
