Robomow RC304 Original Operating Instructions page 22

If the passage is WIDER than 1.5m:
If the Narrow Pass is wider than 1.5m (5 ft.), and you want Robomow to mow the area inside the Narrow Pass, then
you can set the wire as shown in the figure below. Such a setup allows the mower to mow inside the Narrow Pass
while mowing the inner part of the lawn, but prevents it from crossing between the zones.
1. Define the entry to the Narrow Pass - the point you want the mower to start driving towards the Sub-Zone.
2. Set an Perimeter Island at the middle of the Narrow Pass (refer to 4.3.2) as shown in the picture above and
keep a distance of 10 cm (4 inches) from the Perimeter Wire.
3. The island dimensions should be 28 cm (11") along the side and as wide as needed, when keeping 10 cm (4
inches) from both sides.
4. After completing the setup of the wire in the Sub-Zone, make sure you keep 10 cm (4 inches) between the wire
and the island on the way back to the Main Zone.
