5.This step applies to the optional 8 to 12 degree narrow angle lens set only.

a.Remove all lenses shown in Figure 1-8 and put them in a safe place where they will not get scratched.

b.Use Table 1-3 on page 1-14 to install the two lenses in the 8 to 12 degree narrow angle lens set. The name and orientation of each lens is printed on the side of the lens. The arrow printed on each lens must point toward the aperture (i.e., away from the lamp).

6.Lens positions in the lens tube are numbered from 1 to 10, both on the lens tube cover and on the bottom portion of the lens tube. Use those numbers in either Table 1-2 on page 1-14 or Table 1-3 on page 1-14 to move the lenses to correspond with the desired beam angle. The arrow printed on the lens must point toward the front of the fixture (i.e., away from the lamp).

Caution	Handle the lenses by the edge only.
	Fingerprints can result in lower image
	quality. Use only a soft, lint-free cotton
	cloth to clean lenses. Use a mild glass
	cleaning solution if necessary to clean built-
	up dust or dirt.
