The software is immediately responsive on this sharp screen as well.

But the M400 is astonishingly crisp and very legible in all lights, demonstrating that great design and engineering is sometimes better than straight forward pixels Similarly, form a size perspective, its right in the middle of the sports watch size chartsĪ monochrome screen may sound old hat compared to the likes of Garmin forerunner 220 and Fenix 3’s colour screens. Thats not going to be an issue with the M400. I personally wore the Garmin 920XT from its release, but found one of my biggest dislikes was its screaming TRIATHLON WATCH design. The ease of wearing the M400 is very important given the activity tracker on board and the smart notifications, as it can easily double as your primary watch. Yes it’s clearly a digital watch, but blends in very well with a day to day wear, and most importantly feels very comfortable on the wrist -not surprising given the years of experience Polar has in the wearbables market. It doesn’t really look like a sports watch. Yes it would be nice if all of these features had been present with the initial release, but Polar deserve serious credit for continuing to push increasing levels of functionality to the M400 The device Like the smart notifications, Polar have added this functionality through a firmware update. Originally this functionality was possible but only through a separate Polar foot pod, which felt very Year 2000 given the competition. Furthermore, to prevent snap oxidation, clean and dry, as suggested above, after every use to keep from staying wet from sweat or water after a workout.Similarly when the M400 first shipped, in spite of having an accelerometer, used to full effect in the activity tracking side of the watch, it was not used for calculation of cadence such as on the Epson SF-810, or the Garmin 920XT. The transmitter for the H7 should never be bent, so make sure it is worn correctly, to prevent stretching the strap or bending the electrode areas, and stored the H7 in a secured location that is preferably cool and dry. Finally, be mindful of ways to avoid problems with your Polar heart rate monitor.

Also, make sure there is no electromagnetic interference in the immediate area, such as cell phones, high power lines, or televisions. The electrodes on the strap for the H7 will not work without moisture, so put water on them and ensure the strap is tight. Make sure to avoid moisturizing soaps, and do not soak, iron, dry clean or bleach the strap. Make sure to keep the transmitter clean by using water and mild soap, such as Dove Cream Beauty Bathing Bar or Jergens Mild Soap, then dry with a soft cloth. If the H7 is providing no reading, common issues is the heart rate sensor battery may be empty or the H& is not being maintained.
