Make sure both devices are charged and on. To awaken the tracker from the travel- mode, push and hold the button for about 5 seconds.
Start the app and make sure bluetooth is on.
Choose the ViFit Connect Activity Tracker MX3 in "my devices". Press and hold the button for about 10 seconds. If the devices connect, the display will display "Success", if not "Fail" - if that is the case, check if bluetooth is activate, if the app is correctly installed and lower the distance between the devices for the next try.
Also set up the personal settings in the app.
To put on the device, make sure you have a fitting bracelet. If you have it on the left wrist, the button should point to your body, if it's on the right, it should point towards the hand.
