Inconsistent modes (binary with backlight binary without backlight or grayscale) exist between different vision models if the error occurs during planning or between the planned model(s) and the object finder if the error occurs during recognition. During planning combine only models trained with the same mode (either all grayscale or all binary with the same backlight setting). Retrain some models if the wrong mode setting has been used by mistake. During recognition set the object finder mode setting to be similar to that of the planned models. Modes are set using the VTRAIN.FINDER instruction and the V.BACKLIGHT[ ] system switch.
