For RC Models
If the working area borders with a flat area, a flower bed, a small cliff (not more than 0.4in/1cm), or a small stair (up to 2in/5cm), the Perimeter Wire should be laid 8in (20cm) inside the working area. This prevents the wheels from driving into a ditch. Use the shorter distance of the RoboRuler to set the distance of the wire from the lawn edge.
For RS Models
If the working area borders with a flat area, a flower bed, a small cliff (not more than 0.4in/1cm), or a small stair (up to 2in/5cm), the Perimeter Wire should be laid 1ft/32cm inside the working area. This prevents the wheels from driving into a ditch. Use the shorter distance of the RoboRuler to set the distance of the wire from the lawn edge.
For RX Models
If the edge is relatively flat, lay the wire at RoboRuler distance II (10.2in/26cm) from it.
If the edge is a drop, use distance III (36cm) of the RoboRuler to prevent the wheels from driving into a ditch:
If the working area borders with a flower bed (or any other soft obstacle, that you want to avoid Robomow bumping into it), lay the perimeter Wire at distance IV (45cm):
