How should I install the perimeter wire along a wall or high obstacle for models RC & RS ?

RC-Model

If the edge is sloped (a maximum of 10% is allowed) or is bordered with high obstacles such as a wall or fence, the Perimeter Wire should be laid at a distance of 28 cm (11 inches) from the obstacle. Use the longer distance of the RoboRuler to set the distance of the wire from a wall.

RS-Model

If the edge is sloped (a maximum of 15% is allowed) or is bordered with high obstacles such as a wall or fence, the Perimeter Wire should be laid at a distance of 40 cm (1.3 ft) from the obstacle. Use the longer distance of the RoboRuler to set the distance of the wire from a wall.
