Rotational Operation Rotational operation is especially recommended when using the laser receiver. You can select between different rotational speeds. Line Operation In this operation mode, the variable laser beam moves within a limited aperture angle.
OBJ_BUCH-757-006.book Page 30 Wednesday, September 29, 2010 11:21 AM 30 | English When the measuring tool is inclined by more than 8 % after switching on or after a position change, levelling in is no longer possible. In this case, the rotor is stopped, the laser flashes and levelling indicator 3 continuously lights up red. Reposition the measuring tool and wait for it to re-level. Without repositioning, the laser is automatically switched off after 2 minutes and the measuring tool after 2 hours.
