Recall
Use this option to reset the display settings to their original factory
values.
1. Display the OSD.
2. Use the arrow keys (

or
<
) to select the recall box.
3. Press the + or – key to reset the display values to their original
factory settings.
Degauss
The display screen is degaussed automatically each time the monitor is
powered on. This degaussing eliminates color impurities and other
distortions of the display by neutralizing the effects of magnetic fields in
the surrounding environment.
When the unit is left on for a long period, or is repositioned following
power-up, the screen may pick up additional magnetic flux, causing
colors to appear "blotchy" or otherwise distorted. For full effectiveness,
allow at least 20 minutes between manual degaussings. Shorter intervals
may result in an incomplete removal of flux and residual color
impurities.
Note: The internal degauss will not prevent color impurities
caused by local magnetic fields. Metal enclosures can
easily become magnetized by welding and machinery
operations.
Use a hand held degaussing coil to remove residual
magnetism from the enclosure.
Note: If the unit is located near electric transformers, motors,
loudspeakers or other strong magnetic sources, degaussing
alone may not be sufficient to eliminate interference. Try
reorienting the unit relative to the magnetic source or
moving the monitor further away.
If this still does not solve the problem, contact Rockwell
Automation about magnetic shielding.
The degaussing operates for approximately five seconds after selection.
In this duration, the front panel keys are not operational.
