Question about iRobot Roomba Dual Mode Virtual Wall® Barrier 2 Pack

I do not have any pets and cannot find any safety info regarding pets. The virtual wall provides barrier for up to 7 ft and i can imagine some type of RF signal is used and I would expect that safety standards of EU / US must have been applied to be compliant. I would recommend to find this and google :) Sorry, couldn't be of much help.
