CEILING OR SHELF MOUNTING. Regardless of the projector
orientation the DCR retainer should be installed with the prongs closer
to the ceiling so the Panamorph logo is upright after installation.
ABOUT GEOMETRIC DISTORTION. Anamorphic horizontal
expansion lenses create a slight “pincushion” shaped curvature
especially at the edges of the image. The amount of this distortion
decreases as the projection distance is increased for a given
screen size. See the Image Geometry estimator in the Lens Selector
at for approximate distortion to expect. Masking www.panamorph.com
the edges of the image by the screen border makes this distortion
much less noticeable especially for dramatic content.
CLEANING. Small amounts of dust and wipe marks are very
noticeable on lens surfaces with a high brightness projection beam but
typically will not impact the image as much as damage from excessive
cleaning in pursuit of a "perfect" optical surface. Occasionally blowing
off the lens surfaces with clean air is the best way to keep long term
performance. If there is any excessive residue or build-up then it is
recommended that you clean the optics with professional lens cleaning
supplies such as from a camera store while the lens is in front of the lit
beam of the projector. This will allow you to quickly see if the cleaning
process is causing any damage.

IMPORTANT THEATER GUIDANCE
1. Projection screen be in the aspect ratio with a 2.4:1 minimum 2.5″
border.
2. Projector should be horizontally centered on the screen +/- 3 inches
with minimal horizontal lens shift. Projector should vertical position
ideally be between 3” below to 10” above the screen top for best
performance. Beyond these limits may prevent the beam from passing
through the lens at low throw ratios.
3. See the home page for throw distance and www.panamorph.com
screen size compatibility as well as projector viewing mode settings.

INSTALL THE DCR LENS RETAINER. Use projector lens shift
to center the projector lens in its opening. Remove the two front
Phillips assembly screws from the lens/mount assembly and
remove the rear retainer (it comes loosely assembled).
Squeeze the retainer with locking tab disengaged to fit into the
projector lens opening and then relax it so that it nests into the inner
rim of the opening with the prongs level and closest to the ceiling.
Once nested, engage the locking tab to prevent release.
PREPARE THE PROJECTOR. Adjust the projector roll, tilt
and/or yaw so the projector test pattern lines are square to the
screen edges. Now, show a 2.4:1 movie and set the JVC
anamorphic menu setting to . Adjust the Anamorphic C
projector zoom and vertical lens shift so the movie pattern is centered
on and fits the height of the screen. Make sure the projector lens is
clean and as dust free as possible.
INSTALL THE DCR LENS. After removing the rear DCR lens
cover, install the DCR lens/mount assembly over the retainer
prongs; remove the front protective film; rotate the assembly so
that any visible edges of the movie appear the same on the left
and right; then insert and tighten the two assembly screws to secure
(do not over tighten).
ADJUSTMENTS. Tilt the DCR lens in its mount to make any
residual image top curvature the same but opposite that at the
bottom. Make final adjustments to projector zoom and vertical
lens shift to produce the best fit of the image to the screen.
Lock the DCR lens tilt by tightening the single Phillips tilt lock screw
(do not over tighten). As desired you may want to adjust the projector
pixel alignment (see JVC projector instruction manual).
DECIDE HOW TO WATCH 16:9 CONTENT. The “classic”
mode to watch 16:9 content is to set the projector anamorphic
mode to However, , Anamorphic D. Anamorphic C
Anamorphic Off or Zoom will better fill the full cinema format
screen with 16:9 content with various tradeoffs worth exploring. Note
that menus are always created in 16:9 so some type of switch from
Anamorphic C will be necessary to show complete menu content.
