A:AnswerThe HR band isn't interchangeable, which is unfortunate because the constant issues with the band is why I got rid of my HR. I know the Fitbit Alta band can be changed.
A:AnswerManufacturer warranty only lasts for so long. I always purchase extra warranty for those just in case moments.Best Buy warranty will replace the item if anything happens to it! Love that!! They have gotten a lot better with their warranties. They use to pick things apart to not have to cover. So much better now.
A:AnswerNot sure about the "blink" you are talking about but I'll go over some of the reasons why mine blinks:
1. Needs to be charged (shows a battery on display)
2. The back blinks green when it's trying to read you're heart rate
3. You have the "flick" feature on (not sure exactly what it's called but if you flick your wrist it will show you the time)
4. You reached your daily goal (it is also accompanied with a vibration though)
Hopefully this is helpful if you haven't already gotten your answer :)
A:AnswerI haven't seen any directions as to how to get the time to stay on. However if you have the Fitbit app or connected to a computer you can set it to where you just double tap the screen/body area and it can display time, steps, heart rate or miles depending on what you set it up for.
