    Frequently Asked Questions:

    • What sport modes other than running and swimming does the Polar M400 support?
    • Your M400 will come pre-loaded with four sports profiles (including running and cycling), but that’s just to get you started. This watch is designed to switch among several sports modes, giving you a ton of flexibility in the various workouts you participate in and want to track. Sync up to 20 different sports on your M400, all of which you can conveniently locate right on Polar Flow.

    • Does the watch come with a heart rate strap?
    • If you choose “Watch with HRM” in the pull-down menu. Otherwise, use your compatible Bluetooth Smart HRM strap or purchase one separately.

    • I have a heart rate strap, but it's not made by Polar. Will it still work with the M400?
    • The M400 is designed to support any 3rd party strap, as long as it’s Bluetooth Smart. Note that ANT+ only HRM straps will not pair with this device.

    • Even if I am not running, will I still get an accurate HRM and calorie reading during other types of cardio or weight-lifting workouts?
    • The M400 is designed to provide an accurate heart rate and calorie count regardless of the activity you’re participating in, as long as you’re wearing your compatible heart rate strap.

    • How can I use thie watch with my bike?
    • The M400 can be mounted to your handlebar and used as a cycling computer, showing time, distance, calories burned, pace, speed and heart rate.

    • I use the metric system. Will this watch provide data in kilometers/kilograms/centimeters?
    • Absolutely. You simply change from Imperial to Metric within the settings.

    • I hate running and working out with my phone. Do I need my phone on me with this watch?
    • The M400 is designed to show all of your metrics right on your watch face, so you don’t have to keep your phone on or even near you. Use the Polar Flow app on your smartphone after your workout for more complete analysis of your daily, weekly or monthly stats.

    • Yes—the M400 will track your swimming or water aerobics using your wrist movements to glean data. Note that it cannot monitor your actual heart rate if your strap is submerged underwater.
