“Low” light on?

[RoyRoy]

The red “low” light is lit on my Amp MT transmitter. I replaced the transmitter batteries, and it’s still on. I don’t seem to have any functionality issues with the controller -ran two battery packs through the truck with no control issues- Any ideas?

Maybe it’s just the “power” button? But I looks like it should be a “low power indicator. I don’t remember it being on the first few runs. (Weird, huh?)
