I have arrhythmia and it is very important to me to have HR all the time showing. I'm on default face and for sake of accuracy I turned off the wrist HR sensor but I wear the chest HRM. Once the wrist sensor got turned off the unit is not showing HR on the face. If I press Menu then ABC it is showing it but when it goes back to the face it shows it for 5 sec or so and it disappears leaving just two dots instead of numbers. Is there a way to show my HR all the time not just when I do an activity with having the wrist sensor turned off?
