After you've charged the activity tracker and turned it on for the first time, you will run through the setup process. Before you read ahead, it is important to understand how the 'A tap' and 'B tap' commands are used during the setup process, so please reference the following video.
The goal of the setup process is to learn how to use the 'A tap' and 'B tap'. 'A tap' will increase numbers and switch between yes and no commands. 'B tap' is used to confirm a setting — when setting up the clock on your device you will use 'B tap' to switch between the numbers displayed and confirm the yes command once the time is set correctly.
Visual tutorials for each of the setup processes are linked below:
