Problem and Solution
Horizontal or vertical counting error, repair is needed.
Turn telescope or collimation too fast. Sway telescope to be re-
0set in normal position.
Vertical tilt sensor is out of compensation range. Re-level
theodolite. If 'TILT' still displays, repair is needed.
Note: For a temporary solution, the tilt sensor can be turned off.
