6. Commissioning
Place the laser unit in the working position. To switch on
the laser, press button (3). Holding this button for a longer
period will switch the laser off again.
Activating the self-levelling function causes the unit to level
itself automatically. The laser beam does not (yet) flash or
rotate. Once levelling is complete, the beam stays on
constantly and begins to rotate.
Fine adjustments can still be made within the first 30 sec-
onds. These 30 seconds are indicated by a slow flashing of
the white LED (5).
If the unit is out of alignment by
≥ 5°, it is outside the
self-levelling range and cannot level itself automatically.
In this case the laser continues to flash.
The blue and green LEDs indicate which side of the laser unit
is too high. Align the unit by hand until the LEDs go out.
