 Mounting the Optional Lens

Five separate bayonet style lenses can be used with this projector. The descriptions here are for the NP27ZL lens.
Mount other lenses in the same manner.
NOTE:
• 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.
• 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.
• 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.
• Be sure to perform [CALIBRATION] after installation or replacement of the lens. (→ page 17, 126) Calibration corrects the adjust-
able zoom and focus range.
The following lenses need calibration:
- NP26ZL, NP27ZL, NP28ZL, NP29ZL
• 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.
• If you have multiple projectors, be careful of the following:
- The NP25FL, NP26ZL, NP27ZL, NP28ZL, and NP29ZL lenses are designed exclusively for this model of the projector. These
lenses are not available on other projector models.
- The other NEC optional lenses cannot be used with this model of the projector.

Before mounting the lens:

• Prepare a Phillips screwdriver (plus-head)
• Remove the dust cap from the projector.
TIP:
• The projector comes with the dust cap at the time of shipment
