GPS
The M400 has built-in GPS that provides accurate speed and distance measurement for a range of outdoor
sports, and allows you to see your route on map in the Flow app and web service after your session.
M400 includes the following GPS features:
l Altitude, ascent and descent: Real-time altitude measurement, as well as ascended and descended
meters/feet.
l Distance: Accurate distance during and after your session.
l Speed/Pace: Accurate speed/pace information during and after your session.
l Running index: In M400, Running Index is based on heart rate and speed data measured during the
run. It gives information about your performance level, both aerobic fitness and running economy.
l Back to start: Directs you to your starting point in the shortest distance possible, as well as shows the
distance to your starting point. Now you can check out more adventurous routes and explore them
safely, knowing that you're only a touch of a button away from seeing the direction to where you star-
ted.
For best GPS performance, wear M400 on your wrist with the display facing up. Due to the location of the
GPS antenna on the M400, it is not recommended to wear it with the display on the underside of your wrist.
When wearing it on the handlebars of a bike, make sure the display is facing up.
