Christie Captiva Touch User Manual page 7

If the whiteboard frame thickness is greater than 3 mm, the reflected
light interference from the whiteboard frame may be detected by IR
camera. This can compromise the touch function. To reduce the risk
of this happening, it is recommended that a 50 mm boarder is kept
around the projected image instead of 10 mm as shown in diagram on
the previous page.
If the whiteboard frame thickness is less than 3 mm, ensure the
reflected light interference is not observed while doing Step 6 Laser
Beam Alignment (Page 11).

C. Measuring projection surface flatness
Criteria: overall whiteboard flatness <5 mm, flatness requirement is
3
<3 mm at Captiva Touch mounting area.

Equipment: leveling instrument (1.2~1.5 m) and thickness gauge.
C-1) Split projection area into 16 segments equally (see below chart).
Place the leveling instrument on the whiteboard.
C-2) Insert a 5 mm thickness gauge at point 1~9 positions in the order
shown below.
Horizontal:
- Measure point 1, 2 and 3
- Measure point 4, 5 and 6
- Measure point 7, 8 and 9
Vertical:
- Measure point 1, 4 and 7
