To change raster rotation:
1.
Press the Select Mode button until the status LED indicator below
the raster rotation icon is lit.
2.
Use the left and right arrow buttons to adjust the rotation.
Important:
The raster rotation control cannot correct for the effects of
external AC fields such as those produced by large motors,
generators and transformers. Such effects often take the
form of display jitter. Protection against this kind of
magnetic interference requires special shielding.
