A forbidden area that's close to the mowing boundary should 
be a part of the boundary itself, as shown in the picture.
If your lawn has two or more separate areas connected to each 
other by means of a corridor, this should be at least 3 ft wide.
In the case of two islands that are close to each other, it would be 
convenient to lay out the wire as illustrated above.
The Landroid
®
M can travel freely over the boundary wire in 
between the islands and the mowing boundary.
If your lawns are not connected by a corridor that's wide enough, 
then you'll have to pick your Landroid
®
M up and move it to the other 
lawn. Landroid
®
M will mow this lawn no problem, but you'll have to 
bring it back to the charging base when the battery runs out.
