each of the four lens functions is defined as such in software, and that lens mount
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
