Prerequisites

Check if the motor block of the US lens is oriented for the current projector. If not, change the orientation. See “Change the motor block orientation”.

How to install the UST lens

1. Place the primary lens lock in “unlock” position. Handle (reference 1) towards electrical socket (reference 2).

   

2. Check if the secondary lens lock stands in the “unlock” position (reference 3, Image 5–28).

3. Check if the set screw (reference 5) in the lower left corner of the mounting plate on the UST lens is inserted. The set screw should exceed 1.5 mm.

   

4. Gently insert the lens. Ensure the lens connector matches the electrical socket on the lens holder.

   The secondary lens lock (reference 3) makes an audible clicking sound when latching.

   

5. Secure the lens in the lens holder by sliding the primary lens lock handle into the “locked” position (reference 1, Image 5–30).
6. Check if the lens touches the front plate of the Lens Holder.

7. Check if the lens is really secured by trying to pull the lens out of the lens holder.
