Use the following instructions when replacing a projection lens:
NOTE for first time use:
The projection lens is shipped separately from the
projector. Before you install a lens it is important that you remove the lens plug from
the lens opening in the projector.
1. Power down the projector and wait 5 minutes to allow the lamp to cool before
continuing with Step 2.
2. Place the lens cap on the projection lens to protect it from being damaged during
the installation or removal process. For first time installations, remove the rear cap
from the lens – this protective cap is only used during shipping to protect the lens
from damage.
3. When removing the projection lens – Press and hold the “lens release” button
located in the top right corner of the lens panel. Grasping the lens barrel, turn it in
a counter-clockwise direction until it stops. Then pull it forward to remove it
(disconnects from the connector assembly).
OR
When installing a projection lens, make sure Steps 1 and 2 are complete. Slide
the new lens into the lens opening of the projector – make sure to align the
connector that is located on the side of the lens with the connector assembly on
the lens retaining ring. As you connect the lens, you may have to re-align it
slightly until the tabs on the lens will fit into the slots in the lens retaining ring.
With the lens fully inserted (and connected) turn it clockwise until the lens release
button “pops” indicating the lens is fully inserted.
