Friendly Robotics robomow rl350 Operating Manual page 13

A Basic
How It Works
A small wire, called the perimeter wire, is placed around the perimeter of the lawn and any
other areas where you do not want the mower to enter. A small signal is generated from a
device attached to the perimeter wire, called the Perimeter Switch. When turned on, this
signal is carried through the perimeter wire, creating what we define as a virtual wall. The
virtual wall is visible only to the Robomow, keeping the Robomow where you want it, on
your lawn. The perimeter switch must be turned on to activate the perimeter wire before the
Robomow will operate.
