1. Finger touch operation is not working properly
(1) While using the calibration software, if the "Not a valid USB Key for finger
touch whiteboard" error message appears, please follow these steps: Open
"Device Management" and click the "Image Device" option. Check for a
hardware device named "TouchScreen Device ".
(2) If you can recognize this device, please contact your dealer.
(3) If you cannot recognize this device, please check the connections for the
projector camera and the computer.
(4) If there is no problem with the connection, please reconnect to another USB
port.
2. After auto-calibration, the cursor's position does not align with finger
position
Adjust the position of the laser module, Gear A and Gear B, and then do the
auto-calibration again.
3. Automatic Calibration process failure
(1) Select "Tuning Webcam Image Mode" from the "Installation and Debugging"
menu. Check if the webcam image is being displayable on the dazzling
screen, white screen, black screen, and flickering screen.

dealer.
(3) If the webcam image status is showing up as normal, please make sure
there are no objects between the projection screen and the projector camera
during the Automatic Calibration process.
(4) Check that the IR-CUT switcher function is working properly.
(5) Adjust the image brightness accordingly and retry the Automatic Calibration.
(6) Ensure that there isn't any strong ambient light interfering with the projector
camera or screen.

correctly.
(2) Redo Automatic Calibration.
(3) Redo Manual Calibration.
5. Manual Calibration failure
(1) If light spots are not shown in the four corners of projected screen after "Auto
Mask Clutter", manually select "Mask Bitmap Edit" --> "Erase Mask Area"
and erase the area where there are no light spots being displayed until they
appear.
(2) Check that there are no other light spots on the projection screen while in the
"Auto Mask Clutter" process.
