Voice Feedback, Heart rate zone change

[eugeneus]

Hello.
Please describe to me, how the “Voice notification on heart rate zone change” function works in Race and Vertical?
How long should the new pulse zone last to be notified?

@eugeneus The announcement is something like “Heart rate xxx Heart rate zone x”. It appears to trigger when you change zone for a couple of seconds or more so if your HR is sat right on a zone boundary you can get a few announcements in quick succession.
