After this, the device first starts levelling again, which is
shown by the flashing levelling display. After this, the
entered slope settings are approached.
During this procedure, the slope symbol blinks.
Once the values have been reached, the slope settings
and the slope symbol are displayed permanently lit.
If external influences (shock or temperature) change
the position of the device, the system interrupts
rotation and the laser beam, the slope and the warning
display flash rapidly.
If you press the slope key again, you can start grading
again, the device carries out levelling again and
approaches the stored slope settings again.
Important: The laser's mounting position and
possibly also the elevation and direction may,
however, have changed. This means that to be on
the safe side you should switch the device off and
back on again and adjust it.
