6. Installation and Connections
❶ Mounting a lens (sold separately)
This projector can be used with 8 kinds of optional lenses (sold separately). The descriptions here are for the NP18ZL-
4K (standard zoom) lens. Mount other lenses in the same manner. See page
Important:
• For using the following option lenses, be sure to carry out [LENS CALIBRATION] after replacing the lens. (→ page 17, 110)
The following lenses need calibration:
NP16FL-4K, NP17ZL-4K, NP18ZL-4K, NP19ZL-4K, NP20ZL-4K, NP21ZL-4K, NP31ZL-4K
WARNING
(1) Turn off the power and wait for the cooling fan to stop, (2) turn off the main power switch, (3) 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.
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.
• 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 the lens remains detached from the projector for long periods of time, dust may collect within the optical unit
and damage the lens, causing deterioration of projected image.
• Lenses other than specified in this manual cannot be mounted on this projector.
Mounting the lens
1. Remove the dust cap from the projector.
Push the tongue at the top left outward and pull the knob at
the center of the cap.
2. Remove the lens cap on the back of the lens.
• The lens NP18ZL-4K is used as an example.
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.
3. Hold the lens unit aligning the labelled arrow on the unit
coming top and insert the unit to the projector.
Insert the lens slowly all the way in, keeping the positioning
slit at the same angle.
