Setting the lawnmower operation
The angle at which the lawnmower departs from the wire:
The lawnmower travels to the start points along the boundary wire or the shortcut wire, and then turns
away from the wire to start mowing.
You can configure the angle (range) at which the lawnmower deviates from the boundary wire or the
shortcut wire when it starts mowing as below (Default value is from 10° to 170°):
TIPS Use the exit angle to let the lawnmower reach the mowing areas directly instead of using long
wire exit locations.
