Answer to "Why does my bose doesn't turn on and while charging red light flashes"Hello , had the same problem , but on the website , they said that my BOSE is up to date… and i cant do this step : 4. Once your SLM2 is detected by your computer on the http://btu.bose.com site, type "a, d, v" followed by up arrow, down arrow. This will open up the Advanced Settings menu. Edit : okay i understand ! for people who dont catch it , when you are on the website (the internet page) , just type on your keyboard => a d v press arrow up and down. it will open a secret menu ! Thanks a lot .
