Can a base station be installed off the lawn?

Yes, but only for RC and MC models. An installation outside the lawn is called a facility for an "external charging station". A charging station can be installed in two ways: in a corner or in a location outside the lawn.

The external station is set up using program P028 -> ON and the distance of the charging station is defined (press the right arrow key).

You can also watch a video about the installation using the following link.
