3.5 Calibrate guide

To determine the signal strength at various dis-
tances from the guide wire in the actual installa-
tion, the robotic lawnmower performs a calibration
in some situations. The calibration is performed
automatically on the following occasions:
• The first time a new robotic lawnmower
leaves the charging station, for instance
in the start-up sequence.
• In the Settings - Guide calibration
function.
• The first time after Reset user settings.
• The first time after programming the main
circuit boards.
