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)
