I’ve got a 800 and occasionally it flashes up “heart rate too low” It can happen at any point in the ride.

As far as I know I’ve not set any training programmes where my HR has to be above a certain level or zone.

It did it about 5 times on todays ride.

I’ve done searches but nothing comes up, any ideas?

you have gone into cardiac arrest.

Check your pulse 😀

It has some HR zone alarms set up

If it the premium belt then it could be that at fault. Try using some ECG gel to make a good contact, it cheap on ebay and goes a long way

Thanks Jota, that’s it. 8)

I don’t remember setting that up it must have done in rolling around in my pocket/bag, when it’s not locked.

😳

Must remember to turn off or lock when it’s not one the bike
