The wrist unit records up to 30 repeated interval phases. Your interval phase is divided into interval and recovery calculation (if set on) sections, which alternate continuously through your interval phase. As the interval phase changes, the heart rate limits are automatically swapped. For example, when the first phase changes to the second phase, the preset heart rate limits 1 changes to preset heart rate limits 2. You can also swap the heart rate limits by pressing and holding the up button. Repeat until the desired limits are displayed.
