On my old Vision, on power up I would get the DJI tone followed by the 4 beeps. My Vision+ just gives the tone and not the 4 beeps? What's confusing is the DJI Vision+ intro video http://www.dji.com/product/phantom-2-vision-plus/video about 4:54 into video shows the tone with 4 beeps, yet when I called a dealer, his did like mine with only tone no 4 beeps! If you don't have the 4 beeps is that a sign something is wrong?
