Camera guidelines
Guidelines can be set up on the camera views in order to
support a primary check of the area around the machine.
(1) Guideline indicating a distance of about 1 m (39.37 in)
from the rear of the machine.
(2) Guideline indicating a distance of about 2 m (78.74 in)
from the rear of the machine.
(3) Guideline indicating a distance of about 3 m
(118.11 in) from the rear of the machine.
(4) Guideline indicating a distance of about 1 m (39.37 in)
from the right-side of the machine.
(5) Guideline indicating a distance of about 2 m (78.74 in)
from the right-side of the machine.
(6) Guideline indicating a distance of about 3 m
(118.11 in) from the right-side of the machine.
Cautions for the rear view
A distance guideline targets a planar object (e.g. the
ground). Therefore, if a three-dimensional object with an
overhang is approaching, in particular at low distance, the
distance of the overhang is not displayed properly.
The picture provides an example. The machine gets rear-
ward, and approaches an object at a distance (L) of about
1 m (3.3 ft): on the display, the overhang (C) of the object
appears aligned to the position (B) on the ground. Actu-
ally, the position (B) on the ground is beyond the overhang
(C) of the object: the overhang (C) is rather aligned to the
position (A) on the ground. Therefore, there is a risk of
collision between the machine and the object if the ma-
chine is backed referring to the position (B).
