• When the projector is facing up (35 to 150 degrees) or down (-35 to
-150 degrees), tighten the lens torque ring. Note that it could malfunction if
it is over tightened.

• Only remove the lens unit when necessary. If dust or dirt enter the projector,
projection quality deteriorates and it could cause a malfunction.
• Try not to touch the lens section with your hand or fingers. If fingerprints or
oils are left on the surface of the lens, projection quality deteriorates.
• If the lens shift has been done, set the lens shift to the center before replacing
the lens unit.
