Place a post as a pointing reference.
Rotate the knob to unlock the azimuthal convergence adjuster of the optical pointer and set the angle defined by
the standards. Turn the knob to lock the pointer in position.
Use the optical pointer to correctly align the light beams.
Make small movements until reaching the right position.
Keeping the alignment fixed, tighten the screws present on the coupling to the indicated torque paying attention
not to send the locking nut to stroke on the coupling. Therefore tighten the nuts to the indicated torque.
