Mounting a lens (sold separately)
Six separate bayonet style lenses can be used with this projector. The descriptions here are for the NP18ZL (1.3x
zoom) 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.
• 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 following lenses designed exclusively for this projector cannot mounted onto another projector.
- NP16FL/NP17ZL/NP18ZL/NP19ZL/NP20ZL/NP21ZL
Mounting the lens
1. Remove the dust cap from the projector.
2. Remove the lens cap on the back of the lens.
• The lens NP18ZL is used as an example.
3. Insert the lens onto the projector with the arrow mark in
the label on the lens facing upwards.
Insert the lens slowly all the way in, keeping the positioning
slit at the same angle.
