In Manual mode, the generator can be started with the green/start button present on the main unit or the remote unit, and the generator can be stopped by pressing the red/stop button on the main unit or remote unit anytime in the absence of the main supply. The generator will also stop automatically after the presence of the main supply if not stopped with the red/stop button.
