Apple Power Macintosh 5400 series - Manual (Page 136)

Power supply
The power supply in your computer is a high-voltage component and should
not be opened for any reason, even when the computer is off. If the power
supply needs service, contact your Apple-authorized dealer or service
provider.
Cleaning your equipment
Follow these general rules when cleaning the outside of your computer and
its components:
m Use a damp, soft, lint-free cloth to clean the computer’s exterior. Avoid
getting moisture in any openings.
m Don’t use aerosol sprays, solvents, or abrasives.
Cleaning the computer case
To clean the case, do the following:
1 Turn off the computer completely and then disconnect the power plug. (Pull the plug, not
the cord.)
2 Wipe the surfaces lightly with a clean, soft cloth dampened with water.
Cleaning the monitor
To clean the screen, put household glass cleaner on a soft cloth and wipe the
screen. Don’t spray the cleaner directly on the screen, because the liquid
might drip into the monitor or computer.
