  John OconnorAug 20, 2025
  If your AL-KO Lawn Mower indicates 'No loop signal', it could be due to several reasons: there might be no loop signal at all, the boundary cable could be defective, or the loop signal might be too weak. First, check the LED on the base station. Then, check the power supply to the base station by disconnecting and reconnecting the power supply unit. Finally, inspect the boundary cable for any damage and repair it if necessary.

  If your AL-KO Lawn Mower is showing a 'Loop signal weak' message, it could be because the loop signal is too weak or the boundary cable is buried too deep. Check the LED on the base station and the power supply to the base station by disconnecting and reconnecting the power supply unit. Also, raise the boundary cable to the prescribed height, attaching it directly to the lawn if needed.

  If your AL-KO Lawn Mower shows a 'Bad position' error, it could be because the appliance is outside the demarcated lawn surface or the boundary cable has been routed in a criss-cross pattern. Place the appliance on the free, demarcated lawn surface. Also, correct the position of the boundary cable around curves and obstacles, and eliminate any criss-crossing of the cable.

  If your AL-KO Lawn Mower displays 'Cal: signal weak' during calibration, it could be due to a loop signal that is too weak, no loop signal, or a defective boundary cable. Place the appliance in the prescribed calibrating position, aligned precisely at right angles. Check the power supply to the base station by disconnecting and reconnecting the power supply unit. Also, check the boundary cable for damage.
