Apple Power Macintosh 4400 - Manual (Page 176)

Handling the monitor
Follow these procedures for handling a monitor:
m Turn down the screen brightness control if you leave the computer turned
on for extended periods. If the brightness is not turned down, the image on
the screen could “burn in” and damage the screen.
You can also use a “screen saver” program, which dims or varies the
image on the screen when the computer has been idle for a specified
period of time. These programs are available from independent suppliers
and user groups.
m Make sure the vents on the computer are clear and unobstructed.
m If there is interference on the monitor’s screen or on a television or radio
near your computer, move the affected equipment farther away.
Handling the keyboard
Take care not to spill any liquid on the keyboard. If you do, turn off your
computer immediately.
m If you spill liquid that is thin and clear, turn off your computer, unplug the
keyboard, turn it upside down to let the liquid drain out, and let it dry for
24 hours at room temperature. If, after you take these steps, the keyboard
doesn’t work, take it to your Apple-authorized service provider for repair.
m If you spill liquid that is greasy, sweet, or sticky, unplug the keyboard and
take it to your Apple-authorized service provider for repair.
