The GP-4402WW runs a specialized embedded OS. Software-related features include:

Cause: You used a custom font (e.g., Arial) that isn't stored on the HMI. Fix: In GP-Pro EX, go to [Project] > [System Settings] > [Font]. Enable "Download All Fonts" before transferring.

The GP-4402WW is a model within the GP-4000 series of Human Machine Interfaces (HMIs) manufactured by Pro-face (a brand of Schneider Electric).
