1. How to check if the "Installer Mode" function is enabled? 2. I understand that to turn it on "ON / OFF" button for 3 to 5 seconds, and to turn it off should you do the same again? 3. Did I understand correctly that this feature causes that there are no problems turning on the soundbar after prolonged non-use? 4. Does this function need to be activated each time or is it enough once?
