2. Make the antenna tower interface perfectly flat using the tribrach level adjustment screws.
Note, the screw on side 1 is fixed and should never be change to not loose the absolute height
reference. The large bubble level on the positioner should be used to determine if the tower
mounting plate is level. Be sure to look down from directly above the level to make sure the
bubble is centered.
3. Power on the laser plummet using the battery pack. If this is the first measurement, mark the
position of the laser on the ground for future repositioning. This point is precisely on the
rotation axis of the tower. If you are returning to the site, adjust the positioner and leveler so
that the laser beam hits the previously marked rotation center
4. Remove the 4 socket screws on the tower mounting plate, and mount the tower on the plate.
There is an alignment pin on the plate that makes sure that there is only one way to position the
tower. Screw the tower to the mounting plate. When you remove the tower, be sure to screw the
4 screws back on to the plate for future use and storage.
5. Define the antenna elevation angle and set all six antenna holders accordingly. The antenna
illuminates about 60 degrees in elevation, Set the elevation angle so that the beam center aims
at the area of interest. If there are areas that are significantly farther away, adjust the beam to be
centered on these areas.

adjust by rotating the red knobs. The black
screw is to fix the knob setting. At the bottom of
the motor, the connector for the laser battery is
indicated.
