This walkthrough will take you through the entire setup process—from creating your account and adding your new mnsX device, to configuring essential settings and pairing it with your HRM (and Stryd). Once your mnsX is ready, we’ll also guide you through the Connect IQ setup for display and show you how to wear and use your device.
The entire setup guide takes about 5 minutes, or around 10 minutes if you’re new to Connect IQ.
