Mounting a lens (sold separately)
Six separate bayonet style lenses can be used with this projector. The descriptions here are for the Standard lens Type1 (2x 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 before mounting or removing 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:
- When mounting a lens designed exclusively for this projector onto another projector in the WU6181N series, be sure to remove the lens attachment before mounting
the lens on the projector. The lens cannot be mounted if its attachment is on. For the types of lenses that can be mounted and instructions on removing them, see
the lense’s operating instructions.
- Other types of lenses cannot be mounted on this projector.
Mounting the lens
1. Remove the dust cap from the projector.
2. Remove the lens cap on the back of the lens.
3. Insert the lens onto the projector with the yellow-marked protru-
sion on the lens facing upwards.
There is a positioning slit on the projector’s lens insertion slot. Insert
the lens slowly all the way in, keeping the positioning slit at the same
angle.
