5.2.2 Beam Angle Adjustment
All beacons are shipped from the factory preset at an elevation angle of 5
degrees, per FAA requirements.
To adjust the beacon beam to a different angle, perform the following procedure:
1. The beacon head has four screws that secure the lamp to the lamp support
brackets. Loosen these four screws. This will allow the head to pivot on
the top mounting bolts. (See figure 3)
2. Locate the beam elevation label on the right side of the beacon head. (See
figure 3)
3. Locate the sight window at the bottom of the right support bracket. (See
figure 3)
