I have a GH 625M watch with heart rate monitor.
I cannot get the heart rate monitor to work properly.
It is intermittently faulty in that it works some times and other times doesn’t seam to connect with the watch and when it does connect the readings are erratic in any case.
I have changed the batteries in the heart rate monitor and upgraded firmware in the watch but still faulty.
Any help would be greatly appreciated as it appears as though its a synchronizing issue between the watch and the monitor.
