Usage:Use a mobile phone charging plug with an Android data cable to power on and start up. The default frequency is 7.83Hz. Simply enter the keyboard number and press the OK button to successfully set the frequency. For example, to enter the 888Hz frequency - after power on, press the numbers [8] [8] [8] on the keyboard and then press the OK button to successfully set it. Usage of external antenna: Insert one end of the AUX audio cable into any headphone jack on the host, and the other end into the headphone jack on the external antenna board (note: make sure to plug it all the way) to use it directly. The headphone jack can be connected in series, which means multiple headphones can be used. By connecting the AUX audio cable to the corresponding headphone jack position of the device, multiple headphones can be used in series.Package Include: Set 1: 1X Schumann Wave Signal Generator Host 1X power cordSet 2: 1X expansion antenna board 1X AUX audio cableSet 3: 1X Schumann Wave Signal Generator Host 1X power cord 1X expansion antenna board 1X AUX audio cable 1X earphones
