Caution!	Always ground yourself to remove any static
	charge before touching the PC board. Modern
	electronic devices are very sensitive to static
	electric charges. Use a grounding wrist strap at
	all times. Place all electronic components on a
	static-dissipative surface or in a static-shielded
	bag when they are not in the chassis.

Warning! To avoid damaging the computer, always turn off the power supply before setting “Clear CMOS.” Set the jumper back to “3V Battery On” before turning on the power supply.
