3-3. Mounting a lens (sold separately)
Ten separate bayonet style lenses can be used with this projector. The descriptions here are for the
NP13ZL (2x zoom) lens. Mount other lenses in the same manner.
Be sure to carry out [LENS CALIBRATION] after replacing the lens.
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:
• 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.
• Always use the included support kit to secure the projector body and lens unit after affixing the NP50ZL. Please refer to the NP50ZL
Installation Manual for details.
• Always use the support kit (NP01LK, sold separately) to secure the projector body and lens unit after affixing the NP44ML. Please
refer to the support kit’s Instruction Manual for details.
Mounting the lens
1. Remove the dust cap from the projector.
