the side of the front adjustable plate (20).

Adjustment Notes
NOTE:
Except for fine-tuning, the NAV-1 is adjusted
after completing the adjustment process.
However, after restoring power to the projector,
you may want to repeat a particular adjustment
procedure in order to make minor changes.
NOTE:
Depending on your projector model, it may be
necessary to adjust the lens at a slight angle to
the projector lens, which helps to correct
keystone.
NOTE:
If you have difficulty with the lens alignment,
