OPERATION
Roadie 25K User’s Manual
3-71
Turn the horizontal and/or vertical
offset knobs as necessary so that the
image is square on the screen with no
keystoning. For best results, avoid
extreme offsets characterized by corner
vignettes on a white test pattern.
For more vertical offset range, it is
possible that mechanical TILT should
be changed to help compensate for
significant differences in screen and
lens height. Refer back to Section 2.
NOTE: Refer back to Figure 2.13 and
Figure 2.14.
For overall focus
improvement, rotate
the focus adjustment
knob directly under
the lens. For best
results, use a
crosshatch test
pattern or similar,
and focus on the
center of the image.
If the focus quality
differs from edge-to-
edge (whether top, bottom, left or right), the boresight of the lens mount likely needs
correction (see Section 2, Installation and Setup).
NOTES: 1) The anamorphic lens and its mounting structure are optional
components. 2) To install, replace or use the anamorphic lens, refer to the
instructions included with the anamorphic lens mount kit.
To widen a “squeezed” image into a scope (2.39:1) theatre display, swing the 1.25x
anamorphic lens into place in front of the primary zoom lens of the projector. This
lens increases magnification across the width only, regaining the original proportions
in the image, and is often used with screens where side masking can be moved aside.
Occasionally the projector will encounter an error condition that can interrupt normal
operation. Such a condition can be caused by a simple invalid keypad entry, an input
signal error (most common) or a system error. The manner in which users are to be
notified of error conditions is set in the Menu Preferences menu:
•
To see error messages displayed on-screen, select the “
Screen
” option
•
To be notified via a serial communication only, select the “
RS232
” option.
•
To receive both types of notifications, select “
All
”.
•
To disable error messages (except for “invalid user key entry”, which can’t
be hidden), select “
Off
”.
