    Hi Selmake,

    Welcome to the Community!

    I can see that your watch has 1.8.46 software version installed on it and there's a new VERSION 1.8.52 released after that. it's available for download via Sports Connect.

    I would advise you to update your watch with the latest software first and follow the FAQ here to pair the external heart rate monitor: How do I add an external heart rate monitor to my GPS Watch?
