Dead battery light and change on a fender Guitar with Fishman Tuner

I was asked what the lights did on the Fishman tuner/pick up module on my fender guitar. So here’s a quick video showing you what to expect. Obviously if the battery is completely dead you won’t even show a red light like in the video since you won’t have any power at all. Also notice the green light on the tuner blinks about every 2 seconds when the power is turned on the tuner and you aren’t playing. When in doubt change the battery for a good one
