7) Image size adjustment

Rotate (F) screw so that entire table will move to front or back. Placing the adjustment table far
from the screen will make the picture size bigger and closer the table will result the size smaller.
Adjust the size to the point that 2 pixels will be hidden by mullion. The outside line of the internal
test signal will appear for 6 pixels thickness in the image.
Do not adjust this if mechanism comes to an end, further adjustment will damage the mechanism.

ADJUSTMENT

Above adjustments will do positioning and also sizing. The position could be compensated by the

electronic adjustment but the size needs to be done mechanically. It is better to make mechanical
adjustment as much as possible so that any different magnification, the image will appear right.
