Safety warning notice

Å

WARNING: To reduce the possibility of heat-related injuries or of overheating the computer, do not place the computer directly
on your lap or obstruct the computer air vents. Use the computer 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 computer 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).
