    What have you tried and how is it behaving? When you press down from the Clock and go to about does it say Cardio at the top? If not, it is not a Cardio model and you would need to connect a strap for HR. If so, when you go to Sensors>Heart is it set for On? If the answer is yes to both, it may be a defective unit and you need to call Customer Support (don't email or use messenger, take the direct approach and get a live person). To get the number for Customer Support, click the Contact Us link 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

    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.
