repairs at the component level or to make modifications to any printed
wiring board. Improper repairs can create a safety hazard. Any indication
of component replacement or printed wiring board modifications may void
any warranty or exchange allowances.
WARNING:
The computer is designed to be electrically grounded. To
ensure proper operation, plug the AC power cord into a properly grounded
electrical outlet only.
CAUTION:
To properly ventilate the system, you must provide at least 3
inches (7.62 cm) of clearance on the left and right sides of the computer.
