What does it mean when you press the OK button and the "OFF" or “PAUSE” message is displayed while Robomow is in the Base Station? (Relevant to RC/MC models)

This means that the Power box is set to Pause mode, and Robomow will stay at the Base Station and will not start automatically from the Base Station.

This is not a problem. You will just need to again press the mode of operation you want and Robomow will start mowing.
