During Infinia auto motion L-Mode to H-Mode, error mesage Calibration Warning LINDEF Entry = L/R

During Infinia auto motion L-Mode to H-Mode, error mesage Calibration Warning LINDEF Entry = L/R During Infinia auto movement which requires lateral reposition i.e L-Mode to H-Mode, Collimator Change to any mode, etc... seeing error message Calibration Warning LINDEF Entry = L/R (iTrak 13143171) When the detectors are in L-mode and I start a preprogrammed gantry motion (collimator exchange, h-mode, ect) this occurs every time. Very slight hunting of the lateral motion, have to rest my hand on detectors to feel. Gantry has a constant beep… GDU displays "Calibration Warning LINDEF Entry = L/R" for approximate 5 seconds and then disappears Gantry beep stops Detectors pull apart and motion continues as normal If After performing gantry Lateral calibration and problem still occurs, restore original gantry calibration, then perform steps given in resolution.
