Try to reset it to factory settings, Not sure if that works for a new one, but I had to do it to my 60s after being in storage for a few years, after the reset they didn't shut off. it was tricky for one of them, I had to plug it in, push and hold the buttons before it shut off. after a couple trial runs, I was able to get it before it shut down.
