CRT Rotation

3-8
The CRT tilt adjustment aligns the CRT level with the screen. This
is a factory-set adjustment and should not need adjusting unless
the CRT or yoke is moved.
Remove the rear cover (Section 4.2) and tilt the electronic module
up (Sections 3.3).
1. Select Test Pattern 8, Center/Lin.
2. View the color for the CRT that requires rotation. Hide the other
2 colors.
3. In the Geometry menu, set "Reg Enable" to off by unchecking
the box. Unchecking the Reg Enable box temporarily disables
any convergence corrections that have been performed with a
different CRT/Yoke assembly and sets these values to the
default levels so that CRT Rotation can be accomplished
correctly.
