3. Use the lens formulas to find the best corresponding PD with regard to the measured projector-screen distance for the required
screen width.

3.5.4 Lens Installation
How to install ?
Follow the next procedure:
1. Remove the foam rubber in the opening of the lens holder.
2. Take the lens assembly out of its packing material and remove the lens caps on both sides.
3. Move the handle (A) of the lens anchor system to the right. (image 3-6)
4. Push the lens, motors at the top, in the lens block gap horizontally, lining up the motor connector on the lens with the connector
on the lens block (B), until the lens clicks in the lens anchor system. (image 3-7)
Caution: On a table mounted projector, hold the projector when pushing the lens into the lens block to avoid sliding off from
the table.
