How many led lights should the charge 5 be using to detect pulse rate.
I only ever seeing it using one green flashing light?

Hi @Kiwigrahams green is for your heart rate and red is for the oxygen saturation.

Thank you very much.
I have only ever seen the green led not sure when the red is supposed to operate to check O2 levels - maybe when sleeping?
