After turning on:
•
The LCD display turns on and displays the current status of the
Zone80 DG.
•
If set up within the +/-6° self-levelling range (horizontal or vertical),
the Zone80 DG automatically 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 movement or settling of the tri-
pod.
•
The self-levelling system and the H.I.Alert function continue to moni-
tor the position of the laser beam to ensure consistent and accurate
work.
☞
The H.I.Alert function turns on automatically every time the
Zone80 DG is turned on.
