Working with the Lenses

The lens mount secures the primary zoom lens to the projector and provides setup adjustments for correct
boresight, and 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. These
adjustments can be made from the Lens Control menu from the CDP or via one of two menus from the Web
UI: the ILS screen launched from the Main menu or the Channel: Lens menu. Using the knobs on the lens
mount to adjust these positions 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 anamorphic lens (1.25x) can be installed into the 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. Refer to Section 2.8 Offset and
Boresight Alignment for all lens installation and boresight instruction. Refer to Section Channel: Lens Menu,
on page 3-30 for ILS and channel setups.

3.7.1 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.

Focus

• From the Main menu, click ILS. Click the clockwise/counterclockwise buttons as necessary for overall
focus improvements.

Offsets

• From the Main menu, click ILS. Click the up/down/left/right buttons as necessary to adjust the image and
make it square on the screen. For best results, avoid extreme tilts or offsets. Corner vignettes on a white test
pattern indicates extreme offset that should be avoided. If you need more vertical offset range, you can
mechanically adjust tilt to help compensate for significant differences in screen and lens height.

Zoom

• From the Main menu, click ILS. Click the zoom in/out buttons to enlarge or shrink the image in each direc-
tion as necessary.
