display the
Focus menu
against a background of the focus
pattern.
Signal Level
Before adjusting focus you may wish to change the signal
level for the on screen test pattern. This adjustment
DOES
NOT
affect the actual signal level for picture displays, but it
does allow lower signal levels during adjustments so that
they are more precise. Low levels use less beam current.
This, in turn, means that the video spot size is as small as
possible and is not prone to the softening caused by an over
driven signal.
To change the signal level for focus adjustments, first reach
the
Focus menu
as outlined in the steps shown above. At
the
Focus menu
, press
“5”
to display the
Signal Level
Menu
.

: Any change to the signal level in this menu will be effective only during focus adjustments. The signal

Focus Adjustment
Once the signal level has been set, adjust the focus of each color channel using the following steps:
1. From the
Focus menu
press “

” to display the
Green Focus adjustment
screen.
2. Adjust the overall optical focus by loosening the wing nut at the rear of the green (center) lens so that it is
loose, but do not remove it. Rotate the lens barrel by holding the lens with one hand and moving the nut
post with the other along the provided track. When the picture is in sharp focus hand tighten the wing nut.
3. Adjust the edge focus by loosening the wing nut closest to the outer edge of the lens, but do not remove
it. Focus the lens by holding the back of the lens with one hand while you rotate the outer barrel with the
other. You may find it easier to grasp the “wings” that protrude up from the barrel to aid in the focus. Tighten
the wing nut when complete.
