Robomow RC304 Original Operating Instructions page 21

4.3.3 Setting a Narrow Pass
A Narrow Pass is defined as a path that connects two zones of the lawn. The path enables Robomow to drive
between the zones while following the wire, but prevents the mower from crossing between them while mowing
the inner area of the zones. The pass has to be at least 1.2 m (4 ft.) wide to allow Robomow to drive through it.
If the pass is wider than 2 m (6.5 ft.),
There is NO need for any special setting of the Perimeter Wire. Skip to section 4.3.4. Otherwise, you need to follow
the instructions given below in order to set up a Narrow Pass.

If the passage is NARROWER than 1.5m and longer then 2m,
the following wire installation needs to be done – "dual-square installation":
1. Define the entry to the Narrow Pass - the point you want the mower to start driving towards the Sub-Zone.
2. 50 cm (20 inches) from the Narrow Pass entry, set a Perimeter Island (refer to 4.3.2) as shown in the picture
above.
3. Continue to lay the wire along the edge at a proper distance (depending on the edge type) until coming back
to the Narrow Pass entry from the Sub-Zone side.
4. Measure 50cm (20 inches) from that point and lay another Perimeter Island with the same dimensions.
5. After completing the setup of the wire in the Sub-Zone, make sure you keep 10 cm (4 inches) between the wire
and the islands on the way back to the Main Zone.
Main-Zone
The above setup allows Robomow to drive along the wire to reach the Sub-Zone. However, while mowing each
zone individually, it will not cross over to the other zone.
