Hi,
Subject has raised for several other types of Garmin watches and has been resolved in the end. So my first guess this should be a 'bug'.
Wrist heart rate is set to auto and HR strap (BT or Ant+) is connected, still OHR is flahing green.
Also turning OHR from auto to off will not stop the green light of OHR from flashing. Even when HR strap is connected.
Does the FR245 shows the same behaviour at your end?
Thanks for your response.
Kr,
