It is an away from your phone issue, mine goes with my phone or with me, wherever I go, if the phone goes, I take it also but I have noticed if you leave it behind it wants to pair with the device again, once it states that, I close the device and reopen it and it automatically pairs up !! If you already have saved this device in your smart phone it will always look for it !! I have three vehicles and one ear piece, so my smart phone always pairs with what ever vehicle and or ear piece I am near, a simple close the mic and reopen it should wake it up !! If you are getting in your car, the phone will try to convert to hands free in the car, open the phone, it will show the option of all devices, touch "boom" it automatically jumps to boom leaving the hands free of your vehicle !!
