You
can remove a lens to replace it with a different lens. The
projector uses a laser as the light source. As a safety measure,
the light source turns off when the lens is removed. Attach the
lens, and then press the
On
button to turn it back on.
Warning: Wait
at least 30 minutes to remove or replace the lens after turning off
the projector. Touching the lens unit before it cools down may
cause burns.
