Safety Information
The construction of the IBM PS/1 computer provides extra protection against
the risk of electrical shock by either grounding of metal parts or using an
approved system of double insulation. If your computer has the symbol
(on the voltage rating plate on the back of the display), it does not require
grounding. This computer has a power cord with a two-pin plug. If your
computer does
not have the symbol, it must be connected to an electrical
outlet that is properly grounded. This computer has a power cord with a
three-prong plug. 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 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 tele-
phone 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 equiv-
alent to the original parts. Other parts may not have the same safety
features.
Refer service or repairs to qualified service personnel.
If your computer uses lithium batteries, there may be a risk of fire, explosion,
or burns if the batteries are handled incorrectly. To ensure safety:
Do not recharge, disassemble, heat, or incinerate a lithium battery.
Replace the battery with an identical or equivalent type lithium battery.
Discard used lithium batteries according to local country dispositions.
