movements remain accurate to this reference. Regular calibration can correct for
slight eventual mechanical "drifting" of movements over time. It is particularly
recommended whenever the projector is bumped or subjected to vibration, and it is
required whenever a new lens is installed and after certain service procedures.
During calibration, the lens mount will move in various directions for approximately
30 seconds, detecting the center of focus and offset ranges and the extremes for
zoom. A small "Lens Calibrating" message appears on screen during calibration.
Calibration is complete when lens mount movement stops (and the menu
reappears)—note that the lens returns to the previous settings.
NOTES: 1) Calibration with a fixed lens installed causes the zoom calibration to
time-out, possibly delaying the completion of calibration by a few seconds. This is
normal. 2) If calibration with a zoom lens installed takes longer than approximately
30 seconds to complete, make sure the focus motor is engaged as described in 4.5,
Replacing the Lens.
CENTER LENS:
This option removes most vertical and horizontal offset and returns
the lens to the approximate center of the lens opening—the image will be fairly well-
centered on this axis. Note that if centering remains significantly "off", lens mount
bore sight is likely poor. Contact your dealer for service.

(OPTIONAL FUNCTION)
If your projector has a mechanical lens shutter (a.k.a. douser) added, press and hold

NOTES: 1) The status of the shutter is shown in the LCD window on the rear panel of
the projector. 2) Upon power-up, the shutter is open. 3) The lamp remains on.
Mute
Mute*
Mute* temporarily turns the current menu on or off—press and hold
approximately 1 second to toggle with a single key press. Or quickly press and
release Mute* and follow immediately with
correct toggle (useful if you are unsure of the present status). With either method, a
small message appears on screen while the menu is muted.
