button 21.
In sleep mode, the sleep mode indicator 44 on the
laser receiver lights up and the theft alarm indicator

Note: If the laser receiver and the rotational laser level are in
sleep mode for more than 2 h, both are automatically

more than 2.5 h.
– The buttons on the laser receiver are not pressed for more
than 2.5 h.
– The measuring tool is outside of the self-levelling range for
more than 2.5 h and the error code resulting from this is
not rectified (see "Correction of Malfunctions", page 47).
– The measuring tool is not switched on again within 2 h
when sleep mode is activated.
– The anti-drift system is triggered for more than 2.5 h.
– The measuring tool is outside of the operating temperature
range.
Before the measuring tool and laser receiver auto-
