Color is not uniformY Degauss the monitor (page 15).
If you place equipment which generates a magnetic field, such as a loudspeaker, near
the monitor, or you change the direction of the monitor, color may lose uniformity.
The degauss function demagnetizes the metal frame of the CRT to obtain a neutral field
for uniform color reproduction. If a second degauss cycle is needed, allow a minimum
interval of 20 minutes for the best result.

Picture bounces or has wavyY Isolate and eliminate any potential sources of electric or magnetic fields. Common
oscillationscauses for this symptom are electric fans, fluorescent lighting or laser printers.
Y If you have another monitor close to this monitor, increase the distance between them
to reduce the interference.
Y Try changing the direction of the monitor. For example, if it is facing South, turn it so
that it is facing East.
Y Move the monitor away from power lines or place a magnetic shield around it.
Y Try plugging the monitor into a different AC outlet, preferably on a different circuit.
