PCD7.D776 loses contrast settings!

  • Open the project, compile again and then re-download the project.

Procedure for resolving the problem on a PCD7.D776 Rev. 2
In this case the device needs to be returned to your local Saia-Burgess Controls AG sales office for applying a hardware modification.
