Safety Information

The construction of the IBM Aptiva Personal Computer provides extra protection against the risk of electrical shock. This computer has a power cord with a three-prong plug that is required to ground metal parts. It is the responsibility of the person installing the computer to connect it to a properly grounded electrical outlet. Seek professional assistance before using an adapter or extension cord; these devices could interrupt the grounding circuit.

If the computer is connected to an electrical outlet that is incorrectly connected to the building wiring, serious electrical shock could result.

For continued protection against the risk of electrical shock:

•

Connect your computer only to an electrical outlet of the correct voltage. If

you are unsure about the voltage of the electrical outlet you are using,

contact your local power company.

•

If your computer has cables other than the power cords, you must connect

them before plugging the power cord into an electrical outlet. Before

removing these cables, you must first unplug the power cords from the

outlet.

•

If your computer has a telephone connection, do not touch the telephone

cords when there is lightning in the area.

•

Do not use or store the computer in an area where it can become wet.

•

Make sure all replacement parts have characteristics identical or

equivalent to the original parts. Other parts may not have the same safety

features.

•

Personal injury or electrical shock may result if you undertake actions

other than those specifically described in this book. This is particularly true

if you try to service or repair the power supply, monitor, or built-in modem.

Always refer service or repairs to qualified service personnel.
