    Do you have a cardio model (there will be LEDs on the back and under Settings> About it will say Cardio at the top)? If so, is it set at On under Sensors> Heart, not external? If it is not a Cardio model, do you have an external monitor synced to it and have it set for External?

    If all else fails, you may want to call Customer Support to ask them about it, but I would try a factory reset first in case it is just an issue in your firmware install. To do a factory reset, make sure the Connect software is running and dock the device to your computer. The Connect window will open; press the gear at the top right and select factory reset from the next screen. Follow the steps provided and when prompted to register or sign in to MySports, select sign in and use your existing account credentials. It is fairly straightforward and should take less than 5 minutes.

    To get the number for Customer Support, choose Contact Us at the bottom of this page, select the service required and the product name and click Contact Customer Care and then Phone Us. It will give you the phone number for the country your account is registered under (this can be changed by clicking the flag icon in the bottom right corner of the screen).

    I hope this helped answer your question. If so, please mark it as a solution so others can look for it if they have the same question.

    My HRM was giving nonsense readings (e.g. 32 or 37 bpm on a run). A simple solution I tried which worked for me was from the home screen on the watch (Time display), press the down button and scroll down to "Sensors". Then press right and choose "Heart". Turn this off and then back on again. The watch will then start receiving the correct heart rate readings again.
