Can my product measure indoor activity?
Yes. When you set it to Indoor mode, it will measure indoor activity such as walking or running on a treadmill. To set your product to Indoor mode, start GPS positioning, then select Indoor. You can also select Indoor if GPS positioning fails and the product shows the Failed screen.
Note: GPS positioning is disabled when you set the product to Indoor mode, so the product will not record measurements that require GPS signals, such as your workout route. The product will use the built-in stride sensor instead to record measurements.
However, to ensure that your measurements are as accurate as possible, perform GPS positioning outside at least once before using the product indoors. Wait outside for at least 15 minutes with no obstructions overhead after you complete GPS positioning, and keep the product still as you wait. The product will compare data from the stride sensor with this GPS data to record more precise measurements.
