1)Perform the following steps (1) to (3), and incorporate the internal lenses of the lens test projector according to the checking focal- length.

(1)Open the lid of the lens test projector.

(2)Pull up and turn the fixed levers on the right and left sides of the lens test projector.

(3)Remove or insert the lens.

Note: Be sure to have the right position and direction of the lens.
