If you have a new or upgraded device, you will need to associate your new REM-Fit Active with your existing account. You will pair the device inside the REM-Fit Active app. Here is how you do that:
Sign in to the REM-Fit Active app with your existing username and password
Click the settings menu button (the 3 stacked lines in the top left of the screen)
Select "Settings" then "Device Settings" from the menu
Click on the Find button (the magnifying glass icon)
Select your REM-Fit Active from the list
When prompted, click the Sync button.
Once complete, your new REM-Fit Active will now be associated with your account.
