In Advanced – Installation shape mode, the selected
installation shape is shown:
The robotic lawnmower can be set to one of three
garden shapes: Open, Normal and Complex. This
setting affects how the robotic lawnmower covers a
working area when it mows.
• Open: Suitable in a working area consisting
of a large open lawn area with few obstacles
and no passages or when the mowing result
is uneven in steep slopes.
• Normal: Suitable for most working areas.
Designed for working areas with a moderate
number of obstacles and/or passages.
• Complex: Suitable in working areas with
many obstacles and/or passages.
In Calibrate - Guide calibration mode, the guide wire
calibration can be started:
The guide wire may need to be calibrated in rare cas-
es. This must only be done if the robotic lawnmower
itself requests it or if your dealer recommends it.
1. Park the robotic lawnmower in the charging
station.
2. Select Guide calibration and press OK.
3. The robotic lawnmower reverses out of
the charging station and runs a calibration
process over the guide wire,
after which it begins to mow.
In Calibrate - Tilt sensor calibration mode, the tilt sen-
sor calibration can be started:
To calibrate, i.e. reset the tilt sensor: Place the robotic
lawnmower on a horizontal surface. Place the cursor
on Tilt sensor calibration and press OK.
In Calibrate - Cutting height calibration mode, the cut-
ting height calibration can be started:
The cutting height adjustment may need to be cali-
brated in rare cases. This should only be done if the
robotic lawnmower itself asks for it or if your dealer
recommends it. Cutting height adjustment is then
done automatically to min and max height and back
to the chosen cutting height.
1. Select Cutting height calibration and press OK.
2. Await a message stating that the calibration
is complete.
