COMMENTS
Check for brightness
balance between the three
blocks, making sure that
the raster doesn't show
when operator brightness
slideswitch is pushed
completely to the right.
Are the letters
on the top of this
pattern the same size as
the letters at the
bottom? Are they the
same size throughout?
Are there any focus
problems on the screen?
If there are problems,
skip steps 15 and 16. Go
to "Aligning the Terminal

The monitor has several alignments and adjustments. If the
term inal display is out of tolerance in one or two areas, make
adjustments to correct those problems with individual adjust~ents
suggested in Table 4-1. If you change the CRT, the yoke, the
CRT/yoke assembly, or the terminal PCB, you must perform a full
alignment.
Follow these procedures only if the display is out of
tolerance and doesn't match the specification.

o Flat-bladed nonconductive alignment tool
