Warning and Error Messages Warning Message Out of tilt range Meaning What to do Re-level the instrument. Operation, maintenance or adjustment other than those specified in this instruction manual may result in hazardous radiation exposure. If the inputted PN already exists in the memory, then the corresponding point information (coordinate & point code) is displayed in the screen. The result of Free Station, prior to stakeout, is automatically set in the each field of Station Setup. 8. 2 Orientation (Station Point H.
