The RK turns on, but the robot is not running

Send the RK to mow manually, either with the Robomow App or by pressing the Mow button on the RK’s display. Does it start mowing? If it does, it means your schedule is turned off, all days set as inactive, or mowing hours per day are set to zero. Change all these settings and mower should get back to automatic mowing.
