1.6 Safety Precautions

Warning!	Always completely disconnect the power cord
	from your chassis whenever you work with the
	hardware. Do not make connections while the
	power is on. Sensitive electronic components
	can be damaged by sudden power surges. Only
	experienced electronics personnel should open

Caution!	Always ground yourself to remove any static

	batteries according to manufacturer's instruc-
	tions.
