If you are able to successfully calibrate your ActivBoard but calibration is lost over time, please follow the steps below to resolve the issue.
1. Ensure you are logged into the computer as an administrator and calibrate the ActivBoard. This will ensure that calibration settings are stored on the computer for all users.
2. Update your ActivDriver to the latest version. Please refer to article 1012 for further details.
3. Calibrate the ActivBoard using the Precision option. Please see article 1046 for further details.
4. Test the ActivBoard with a different ActivPen or ActivWand.
5. Connect the ActivBoard to another computer using an alternative USB or serial cable.
6. Ensure that the projected image is stable and does not overfill the ActivBoard surface or marked active area. If the projector is not secured tightly on the ActivBoard system, or if the image is too large, calibration will be inaccurate. Please contact your system installer if the image is not correctly aligned.
7. Remove any extension cables and USB boosters that are connected to your system and recalibrate the ActivBoard.
