      We have a teacher using an older Promethean Board (ABV287PRO) and he indicates that after calibrating the board, it will only last for about 20 minutes and then the touch pen stops working correctly.  He’ll recalibrate and the cycle continues.  Any ideas on how to troubleshoot this?

      Hi David,

      Thank you for your post.

      The issue you are reporting is typical of ABV300PROs, ABV500PROs and ABV300E100 with outdated firmware.

      Please make sure the firmware is up to date on the latest non-HID version: https://support.prometheanworld.com/article/1038/

      To then upgrade it again selecting the internet option instead of file.

      For more information please see: https://support.prometheanworld.com/article/1779/

       

      If on the latest version of ActivDriver and firmware the issue still occurs, please let us know and we will open a support case.

       

      Kind regards,

      Thibaut
