The operating environment of the PC System can have a large effect on the lon-
gevity and reliability of the system. Improper operating environments can lead to
malfunction, failure, and other unforeseeable problems with the PC System. Be
sure that the operating environment is within the specified conditions at installa-
tion and remains within the specified conditions during the life of the system.
Observe the following precautions when using the PC System.
Always heed these precautions. Failure to abide by the following precautions
could lead to serious or possibly fatal injury.
