3.8.4 Electronic fine adjustment of the opening and closing angles
It is possible to set the position of the ProFLECT II i in closed condition in order to achieve a smooth
closure of ceiling construction and covering.
The position of the ProFLECT II i in open condition defines the position of the projected image on
the screen.
Both positions can be set using the “Up” and “Down” buttons. Proceed as follows:
CAUTION: The clamping protection is not active during this setup process!
 Press and hold both buttons (UP and DOWN) simultaneaously for at least 3 seconds. The
ProFLECT II i will move to the open position (if it is not there already).
 Using the “Up” button will reduce the opening angle (ProFLECT II i opens less), using the “Down”
button will increase it. Pressing once corresponds to a movement of the projected image by approx.
1 cm for a projection distance of 5 meters. If, for example, the projection is to be moved downwards
by approx. 10 cm, press the “Down” button 10x repeatedly. When doing so, do not pause longer than
1 second in between each button press, because then the controller will detect the end of the input.
In this case, the ProFLECT II i will partially close, in order to then move to the final position. Please
check if that position is correct and, if necessary, make corrections as instructed.
 If the position is as required, press both buttons simultaneously (for at least 0.25 sec.). The
ProFLECT II i will then move to the close position.
 Then the upper closing point can be corrected as described. Again: “Up” will close the ProFLECT II i
more, “Down” less.
 After the upper point has been set, press both buttons again simultaneously (at least 0.25 sec.). The
setting has then been completed and the ProFLECT II i will run in normal mode. All settings are
saved and available even after power failure.
 If these settings are not sufficient, i.e. the ceiling closing plate is not yet in parallel to the ceiling,
mechanical fine adjustments can be performed (see 3.8.6).
3.8.5 Mechanical fine adjustment of the ceiling closing plate
CAUTION: Please perform the electronic adjustments first as described in chapter 3.8.4.
The following options are available for the mechanical fine adjustment of the ceiling closing plate:
- Two slotted holes (12 mm) of both mounting brackets that are used for mounting the large mirror
flap over the engaging mechanism of the ProFLECT II i (Fig.1). When loosening both screws,
the mirror plate can be moved up or down.
