When you press the power button for less than one second, GODJ will enter Stand-by mode. When in Stand-by mode, the LCD screens are turned off and all operations except for the crossfader become locked. GODJ will continue playing the music when in stand-by mode. This will conserve your battery energy and extend up to 24 hours on a full charge (One charge lasts 12 hours when GO DJ is fully awake). Stand-by mode is useful when you want GODJ to mix automatically when in AutoDJ mode.
