-select an easy part of your lawn and learn what your mower does and how to program your robot mower
-install your virtual wire on top of your lawn with pegs.
(first cut strip around edge of lawn really short so wire is close to ground)
-find the perfect spot for the charging-station make sure it is 100% level and on hard ground and has straight 2m level run into station (maybe on pavers and the virtual-wire is placed exactly on the arrow) if you stand in the centre lawn make sure mower goes clockwise into charger.
-find out if you have to change your garden-design to overcome areas the mower can't mow
-any corners less then 90 degrees are a challenge
-any piece of lawn less then 2m wide are a challenge
-your mower can climb 30˚ hills and turn, but not descend slopes and turn (it will slip if the lawn is wet and go past your wire)
-if your lawn has to be divided into areas make sure your design will work
-do make sure to place wire 40cm from any object like house wall or fence you can always shift wire closer. (but it will work ?)
-do make sure that there is no right-angle corner!!!! always have a radius of 20 cm (or use install guide for virtual wire out of Manual)
