Working with the Lens

The CP2000-SB lens mount secures the primary zoom
lens to the projection head. It provides 1) setup
adjustments for correct boresight, and 2) automatically
controlled focus, zoom and offsets for general use. To
save the focus, offset and zoom settings to the channel,
you must make the adjustments using the motorized lens
mount adjustment features in the Main: Lens menu or
Custom: Lens menu from the TPC. Using the knobs on
the lens mount to adjust each position does not save the
settings to the channel. They are designed for temporary
use and will therefore be lost once the channel changes.
NOTE: After any manual adjustment, click Lens Reset in
the Advanced: Lens menu to ensure ILS settings are
properly recalled.
An optional auxiliary lens (1.25x or 1.26x) can be
installed into an optional auxiliary lens mount, then
swung into place in front of the primary lens to widen a
squeezed image into a properly proportioned scope
anamorphic cinema display. It is typically used in theatres
having side masks that are retracted for scope images, or in theatres having fixed side masking but a very short
throw ratio (throw ratio= throw distance/screen width). To move the auxiliary lens, select the Anamorphic
Lens button on the Main menu of the TPC. Refer to
installation and boresight instructions. Refer to
setup.

3.9.1 Lens Mount Functions

Mount (MALM) is present, ensure to move the MALM
to the OUT position before performing any lens
calibrate or reset functions on the Motorized Primary
Lens Mount to prevent collision between the
projection lens and the MALM. 2) Hazardous moving
parts. Keep fingers and other body parts away.
NOTES: 1) Projector must be fully assembled and powered up
in its final location. 2) Keep clear of rotating parts. Remotely
operated motors may start to spin without warning. 3) Avoid
long hair, jewelry, and loose clothing exposure to the knobs
during manual adjustment. 4) In case of emergency, unplug the
line cord to immediately halt movement of the lens mount. 5)
When adjusting the Focus, Offset, and Zoom, you may
experience a slight delay in the response rate of the lens upon selecting the buttons.

Zoom

From the Main: Lens menu, click the zoom in/out buttons to enlarge or shrink the image in each direction as
necessary.
