Avoid placing two CRT monitors
too close to one another; CRT monitors produce magnetic fields which may
cause damage to one or both displays; the damage done to a monitor
because of magnetism, is usually represented as shimmering images.
Keep the monitor's vents
unobstructed
Keep the monitor’s case clean
and free of any objects that may cover the heat-release vents in the
case.
Use only the length of wire
needed
Whenever possible, keep wire
connections as short as possible; the longer a signal travels, the more
it gets exposed to interference.
Avoid interference
Avoid placing a monitor too
close to power lines so as to allow the monitor’s cables to touch
electrical wires; this causes interference in the signal transmission
and it is seen onscreen as grainy images or images broken and wavy.
Storing media correctly
Store all media, particularly
magnetic media away from electronics and unshielded items; the
electronics heat can damage storage media and magnetism can spoil a
diskette’s saved data.
