Safety warning notice

WARNING!

To reduce the possibility of heat-related injuries or of overheating the device, do not

place the device directly on your lap or obstruct the device air vents. Use the device only on a hard, flat

surface. Do not allow another hard surface, such as an adjoining optional printer, or a soft surface,

such as pillows or rugs or clothing, to block airflow. Also, do not allow the AC adapter to contact the

skin or a soft surface, such as pillows or rugs or clothing, during operation. The device and the AC

adapter comply with the user-accessible surface temperature limits defined by the International

Standard for Safety of Information Technology Equipment (IEC 60950).
