Unacceptable Screen Dimensions

Try adjusting the monitor's vertical and horizontal controls. If
you turn any of the controls fully one direction or the other and
still cannot achieve the desired result, you may need to take the
monitor to a service technician who can adjust the video
alignment controls inside the monitor. DO NOT remove the
monitor's cover yourself! There are extremely high and
dangerous voltages waiting inside!

No 80 Column Display

If you have an acceptable 40 column display, but no 80 column
display when the Viewmaster 80 is activated (PR#3), first check
to see that the Viewmaster 80 is actually installed in slot 3. Next,
turn the computer off, remove the Viewmaster 80, verify that all
of the integrated circuit "chips" on the card are securely seated,
and reinstall it, making sure that it is fully seated in expansion
slot 3.
