Mounting a lens (sold separately)
Three separate bayonet style lenses can be used with this projector. The descriptions here are for the NP41ZL lens.
Mount other lenses in the same manner.
WARNING:
(1) Turn off the power and wait for the cooling fan to stop, (2) disconnect the power cord and wait for the unit to
cool before mounting or removing the lens. Failure to do so can result in eye injury, electric shock, or burn injuries.
Important:
• Be sure to carry out [LENS CALIBRATION] after replacing the lens.
• The projector and lenses are made of precision parts. Do not subject them to shock or excessive forces.
• Remove the separately sold lens 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 dismounting the lens from the projector, return the lens position to the home position before turning off the power. Failure
to do so may prevent the lens from being mounted or dismounted because of narrow space between the projector and 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.
Mounting the lens
1. Remove the dust cap from the projector.
2. Remove the lens cap on the back of the lens.
NOTE:
• Make sure to remove the lens cap at the unit back side. If the lens unit
with the lens cap remaining on is installed on the projector, it may cause
of malfunction.
