• The other NEC optional lenses are not available on this model.
• The projector and lenses are made of precision parts. Do not subject them to shock or excessive forces.
• Remove the lens unit when moving the projector. If not, the lens could be subject to shock while the projector
is being moved, damaging the lens and the lens shift mechanism.
• When mounting (removing) the lens unit, return the lens position to the center before turning off the projector
power. If you do not return the lens position to the center, the lens may interfere and prevent you from removing
(mounting) the front cover.
• Turn off the power and wait for the cooling fan to stop and turn off the main power switch before mounting or
removing the lens.
• Never touch the lens surface while the projector is operating.
• Be very careful not to let dirt, grease, etc., on the lens surface and not to scratch the lens surface.
• Perform these operations on a flat surface over a piece of cloth, etc., to prevent the lens from getting scratched.
• When leaving the lens off the projector for long periods of time, mount the dust cap on the projector to prevent
dust or dirt from getting inside.
Preparation: Remove the front cover. (page 45)
