Disabling Bluetooth/EMF on a Vívosmart 4



Contemplating buying a Vivosmart 4 for my wife’s birthday but before I purchase I was seeking some reassurance Bluetooth EMF can be turned off. 


I have an Oura ring that allows me to operate in Airplane mode until I sync with my phone and I’m hoping the Vivosmart 4 will similarly allow this?


I love the features but I’m concerned that if this is not possible I’ll have to consider an inferior device which allows for Bluetooth to be disconnected.
