Prerequisites

Some lenses are installed with a lens support. The lens support must be detached from the lens body before removing the lens from the projector. See chapter “ILD UST lenses”.

How to remove the lens

1. Set the lens holder in the center position.

   • Using Pulse OSD: Menu > Installation > Optics > Shift to center
   • Using Pulse Prospector: Setup > Optics > Optical Shift > Shift to center

   A shift to the center ensures that the lens holder is in the on-axis position, which avoids damaging the internal optics when removing the lens.

2. Switch off the projector or activate the projector shutter.(shutter is activated when the shutter icon on the projector keypad is red).
3. Support the lens with one hand.

4. Push the lens unlock button with the other hand while rotating the lens a few degrees counter clock wise.

   The lens unlock button is located bottom right of the lens holder.

   

5. Hold the lens with both hands and rotate it further counter clockwise until the short red line on the lens body is aligned with the red line on the projector top cover (reference 1).

   

6. Pull the lens straight out of the lens holder.

   

7. Mount protective caps on the lens and lens holder.
