a. Remove dome assembly by grasping the die-cast ring attached to the dome and turning it
counter-clockwise.
b. Remove three #10 hex head screws that secure strobe-spinning assembly to housing.
c. Remove strobe-spinning assembly.
d. If desired, remove the factory field wiring leads from the terminal block.
