3. Use the lens formulas to
fi
nd the best corresponding PD with regard to the measured projector-screen distance for the required
screen width SW.
Tip:
Divide PD by SW to determine the approximately required throw ratio. Choose a lens, which captures the calculated
throw ratio. Use the lens formula of the chosen lens to recalculate exactly.

How to install a lens into the projector lens holder ?
1. Remove the foam rubber in the opening of the lens holder if not removed yet.
2. Take the lens assembly out of its packing material and remove the lens caps on both sides.
3. Place the lens holder in the “unlocked” position by moving the lens lock handle (A) towards the lens power supply socket (B) as
