All error messages produced by Omega software are written in plain English. The only exception is when an error occurs in the underlying code, generating a message like:
PC9 exception fault.
segmentation fault (client). For firmware versions prior to 1.4.4 (Pencarrow), this error can occur if the Omega terminal's theme version does not match its firmware version. (You can check the version number of themes and firmware using Omega Administrator.)
If the theme and firmware version numbers match, then this error may indicate a low-level bug in the Omega terminal. Contact Pharos Support.
