Working without Laser Receiver (see figure G)
Under favourable light conditions (dark environ-
ment) and for short distances, it is possible to
work without the laser receiver. For better visi-
bility of the laser beam, either select line opera-
tion, or select point operation and manually ro-
tate the rotation head 10 to the target location.
Working with the Laser Receiver (see figure H)
Under unfavourable light conditions (bright
environment, direct sunlight) and for larger dis-
tances, use the laser receiver for improved find-
ing of the laser beam. When working with the
laser receiver, select rotational operation with
the highest rotational speed.

Measuring Over Long Distances (see figure I)
When measuring over long distances, the laser
receiver must be used to find the laser beam. In
order to reduce interferences, the measuring
tool should always be set up in the centre of the
work surface and on a tripod.
Working Outdoors (see figure J)
The laser receiver should always be used when
working outdoors.
When working on unsafe ground, mount the
measuring tool onto the tripod 48. Activate the
shock-warning function in order to avoid faulty
measurements in case of ground vibrations or
shock to the measuring tool.
