4.1 Pan, Zoom and Focus Speed and Nudge Functions
The Pan, Zoom and Focus buttons can be used to manually control the projected image. All of the motors may be driven
at one of four speeds to make small incremental adjustments. In addition a nudge function is implemented. When any of
the control keys are pressed and released, the associated motors will be turned on for a short period of time, causing a
small incremental change in the image. In the following descriptions this nomenclature is used:
P = a quick button press and release – press and release time each less that about 0.25 seconds
H = the button is held down
PP = two quick button presses and releases – down times and intervening up times each less that about 0.25
seconds, etc.
..PH = One or more quick button presses and releases followed by a hold
The nudge function generates small changes in lens position,etc., by applying power to the associated motor for one of
four time intervals: 12.5, 25, 50 or 100 milliseconds. Nudges are generated by a number of quick button depressions and
releases. Nudge increments are controlled by the number of quick button presses – up to four. More than four are treated
the same as four.
P – smallest change – 12.5 msec
PP – 25 msec
PPP – 50 msec
PPPP – largest change – 100 msec
PP..PP – largest change – 100 msec
