Do I have to wear the armband all the time? What happens if I take it off?

Answer: When you upload your armband to your dotFIT Me Program, you will have the opportunity to tell the program what you were doing during any "off-body" time by clicking on the EDIT OFF-BODY button. Off-body time is any time outside of your sleeping hours that you don't wear the armband for 30 minutes or more. In other words, if you take the armband off for 20 minutes and put it back on, the armband/program will assume an average number of calories burned for that 20 minutes based on how many calories you usually burn at that time of day. The more you wear the armband, the more accurate your values will be.
