Image 5-1: Lens calculator
The Lens Calculator can also be used to determine the position of the projector when the lens type
and screen width is known.
Due to lens tolerances the results of calculated values may be different from measured values.
These difference may vary +/- 5%.

Lens mechanism
The mechanism to hold the lens on the projector is a "turn and click" system. This double fixation of lens
(without safety cable) allows to avoid lens falling out in case of single fault condition when the projector is used
above an audience.
The lens mount and lens button are designed to prevent damage to the lens board while providing an easy
and stable lens change procedure.
The lens button (reference 1) is located at the bottom right of the lens mount (reference 2). The button can
switch between two positions:
• default position, the lens mechanism is locked.
• pressed, the lens mechanism is unlocked.
