(2)Open the camera front cover slide the camera onto the horn of the collimator. Make sure that the camera is all the way on the horn so that the camera is captured by the spring latches.
(3)Swing the collimator infinity lens to its vertical position. (Be sure the 8’ lens is not in the viewing path.)
(4)Look into the camera viewfinder while turning the focus wheel counterclockwise until the image appears sharp. Look at the collimator center target (top group of lines) and note the number .63. This number and the lines should have maximum clarity as the focusing wheel reaches infinity.
(5)if the wheel stops before the focus is sharp, make the following adjustment before continuing with the collimation procedure.
Spring Loaded Idler Gears
(a)With the camera still on the colimator, slip special tool #11939 over the lens and push it in, toward the back of the camera. This will disengage the idler gear from the focus wheel, allowing the lens to be turned without affecting the focus wheel.
(b)With the focus wheel still set it its infinity position, look through the camera while turing the lens. (This is done by maintaining pressure on the tool.) While turning it, you will be able to see the target through the opening in the tool.
(c)When the image is sharpest, release the special tool to reengage the refocused lens to the focus wheel. (Continue setp 6.)
Non Spring Loaded Idler Gears
(a)Remove the camerar from the collimator
(b)Loosen the adjusting screw at the bottom of the shutter housing so the idler gear no longer engages the focus wheel and lens barrel (Figure
(c)Return the camera to the collimator and adjust the infinity focus by rotating the lens barrel while maintaining the infinity position on the focus wheel.
(d)When the focus is sharpest, remove the camera from the collimator and tighten the adjustement screw. Returns the camera to the collimator and continue with step 6.

(6)Verify the infinity setting. Do this by observing the vertical line target through the collimator infinity lens and the camera optics. The line should be straight within the tolerance in Figure
(7)Swing the collimator infinity lens back down to its horizontal position, out of the viewing path of the camera. Turn the camera focus wheel to the 10.4’ setting.
