than 5 seconds to shift the lens to the center 

position.

stop, and then turn off the Main On/Off switch or 

unplug the AC power cord.

About the lens antitheft screw

To prevent removal of the installed lens, move the lens 

to the leftmost position with the Lens Shift function, and 

then loosen an antitheft screw on the right side of the 

lens until it will no longer be loosened.

Doing so makes the Lens release button unworkable 

and the lens will not be removed from the projector.

When you replace the lens, tighten the antitheft screw.
