Black Thumbwheel

How do I turn the thumbwheel

Turn the wheel using your thumb and finger. Do not block the line of sight between the WallCast unit and the LED Sensor.

I have rotated the thumbwheel 3 times and the number 9 is still displayed

If you have fully turned the black thumbwheel and number 8 or 9 continues to be displayed then you need to check you have not added too many spacers. Check the correct number of spacers are fitted. Measure the thickness of your board with the supplied measurement scale. Use the table in the Install Guide to confirm the spacers required.

If you are certain the correct spacers are fitted then visit support.prometheanworld.com as a new WallCast unit may be required.
