better to move the charging station to a
better place in the working area.

Testing selected settings can be seen as a natural part of
the installation.
To test the selected settings:
1. Place the robotic lawnmower about 3 meters from
the wire to be tested (boundary wire or one of the
guide wires), facing the wire.
2. Use the right/left arrow key to select Test under
the wire to be tested. Press OK.
3. Press START and close the display hatch.
Check that the robotic lawnmower follows the
guide wire all the way to the charging station and
that it docks with the charging station. The test
is approved only if the robotic lawnmower is able
to follow the guide wire the entire distance to the
charging station and docks at the first attempt.
If the robotic lawnmower is unable to dock on
the first attempt, it will automatically try again.
The installation is not approved if the robotic
lawnmower needs two or more attempts to dock
with the charging station.
Normal causes as to why the robotic lawnmower
cannot follow the wire are that obstacles close to
the wire have not been isolated or that the guide
wire has not been laid at an angle on a steep
slope. Check that the charging station, boundary
wire and guide wire are installed in accordance
with the instructions in Chapters 3.2, 3.4 and 3.6.
If manual settings are done, the wrong corridor
width may also have been selected.
4. The test is approved when the robotic lawnmower
can follow the selected wire to the charging station
and dock with it on the first attempt without any
problems.
Using Test, the robotic lawnmower travels the maximum
distance from the wire defined by the selected corridor
width.
