Anyone have the newer lifeline (no manual radio function)? I just got mine and it looks like I can't turn it off. It just sits here and flashes a blue light every second. No matter if i push or hold the on off button, nothing happens. Just continuously flashes this blue light every second no matter what I do. Doesn't really talk about this in the manual. Says to push the blue button to turn it off and I assume off would have no flashing lights at all.
