Veryfitpro Green Light. But this FUNky green hits the sweet bit in me. If none of the above methods resolve the issue, check whether there is a working green light on the back of the band's body when you activate the heart rate detection feature on the band.
This manual addresses the safety guidelines, warranty and operating instructions.
Have to say first impressions it feels light and I love the colour, I usually go for black so it looks expensive…yes.
VeryFitPro For PC is a very useful app that allows you to record every moment accurately. If you open the app and try to get a heart rate reading, the light will glow. The light flashes on the blood pulsing under your skin and a light sensitive photodiode measures the amount of green light absorbed.
