If set up within the +/-6° self-levelling range (horizontal or vertical), the Zone80 DG auto-
matically levels to create an accurate horizontal plane of laser light.
•
Once levelled, the head starts rotating and the Zone80 DG is ready for use.

The H.I.Alert system becomes active 30 seconds after completing the self-levelling. The
H.I.Alert system protects the Zone80 DG against changes in elevation caused by any move-
ment or settling of the tripod.
•
The self-levelling system and the H.I.Alert function continue to monitor the position of the
laser beam to ensure consistent and accurate work.
