8. Now you will see a light spot
from the light source,
provided it is turned on.
Focus by moving the outer
part as indicated in the
adjacent figure until you get
the smallest and sharpest
possible spot. The size of the
square spot depends on the
distance between the
receiver and the transmitter;
the longer the path the
smaller the spot.
Use the lens hood to
suppress ambient light for a
better visibility of the focused
light.
9. Align the transmitter using the
supplied Allen key by turning
the two screws without
springs until the focused spot
appears in the center of the
crosshair.
Do not turn the screws with
the springs!
10. Remove the coarse aligning
unit and replace it with the
fine aligning unit.
Verify if the target of the fine
alignment unit is orientated
such that the "B" axis points
to the purging inlet of the
flange.
