Does a flip sky vx3 pro receiver have any lights when working?

I finally got my setup working and in the water yesterday and it had looked like my battery had died very quickly. After charging and plugging everything back in the remote won’t pair. It turns on and the esc beeps when pigged in. I have no lights on the remotes receiver so I’m thinking maybe that is the issue? Can someone please confirm if the receiver should have a light on? The remote and esc are second hand.
