the raster width, it should not be used solely for that
purpose. The placement of the linearity sleeve should
be optimized for the best linearity.
(4) Readjust LlOl for proper width.
(5) Observe final horizontal linearity and width, and touch
up either adjustment if needed.
No horizontal hold control is used in this monitor. The raster should be
properly locked and centered when the horizontal drive signals as described in
