How do I establish Bluetooth call connectivity?

There are two ways to establish Bluetooth connectivity.

Automatic:
Follow the pairing process to pair Noise fit Venture with the Noise Fit app. Once paired, the watch’s Bluetooth calling feature would be activated automatically.
 Connect it with your phone’s Bluetooth to use the calling feature conveniently.

Manual:

 In case the Bluetooth call connectivity prompt does not pop up then you can establish the connection manually.
 On your phone: Go to Settings. Turn on the Bluetooth search and pair Noise fit Venture to use the watch to make calls.
