Looking at the faqs Here about the band charge it until the battery indicator shows Green.
Amber is 50% and Red is low it is a solid Red and then changes to a blinking Red to show critical.
The band should last roughly a month on each charge.
So my advice is to charge it and take it off when the indicator is green @cpsmith

Hi @bandofbrothers - yeah, I saw that, however, I have just unpacked the box, and the band is not showing any info on the screen. It is completely black, so I assumed it needed fully charging before first use.
I have been charging it for about an hour, and the main body of the band is quite warm, so I suspect it is charging ok. However there is still no activity on the screen. There does not appear to be an on/off switch, so I assumed it would become active as soon as there was any charge, but so far there is no sign of life.
Can I ask if this was resolved? I just purchased a sos band and its charging (I think, red battery is flashing) but its been charging for over an hour now
