Normal reception
Wire signal OK:
The text "Wire signal OK" 
appears on the display. The 
robotic mower and docking 
station are correctly linked.
Continue initial installation by 
pressing the OK button.
Interrupted reception
The robotic mower receives no 
wire signal:
The text "No wire signal" 
appears on the display.
The robotic mower receives a 
faulty wire signal:
The text "Check wire signal" 
appears on the display.
The robotic mower receives a 
reversed-polarity wire signal:
The text "Connections swapped 
or iMOW® outside" appears on 
the display.
Possible cause:
– Temporary malfunction
– Robotic mower is not docked
– Perimeter wire has been connected 
incorrectly (reversed polarity)
– Docking station is switched off or not 
connected to mains supply
– Faulty plug connections
– Minimum perimeter wire length not 
reached
– A coiled power cable in the vicinity of 
the docking station
– Perimeter wire ends excessively long or 
not sufficiently twisted together
– Perimeter wire break
– Extraneous signals such as a mobile 
phone or the signal from another 
docking station
– Live underground cables, reinforced 
concrete or disruptive metals in the 
ground under the docking station
– Maximum length of the perimeter wire 
exceeded (Ö 12.1)
Remedy:
– Repeat linking without other corrective 
action
– Dock the robotic mower (Ö 15.6)
– Connect the perimeter wire ends 
correctly (Ö 9.10)
– Check the docking station mains 
connection, roll out the power cable in 
the vicinity of the docking station, do not 
set down coiled
– Check the seating of the wire ends in 
the terminal block, shorten excessively 
long wire ends and twist the wire ends 
together (Ö 9.10)
– For smaller mowing areas with a wire 
length of less than 80 m, the AKM 100 
supplied must be installed together with 
the perimeter wire (Ö 9.9)
– Check the LED indicator on the docking 
station (Ö 13.1)
– Repair the wire break
– Switch off mobile phones or nearby 
docking stations
– Change the position of the docking 
station or remove interference sources 
under the docking station
– Use a perimeter wire with larger cross 
section (special accessory)
Following the appropriate corrective 
action, repeat linking by pressing the 
OK button.
9.12 Checking installation
Start edge following by pressing the 
OK button – this does not activate the 
mowing blade.
"Standard" energy mode is 
activated following successful 
linking. (Ö 11.10)
Contact your specialist dealer if the 
measures described above do not 
result in a correct wire signal.
