Thanks Bart,Got mine today as well. Will admit that if the battery cover said "twist" or had arrows indicating to twist, it might have made sense. No issues though. Works just fine for now.
Thanks Daryl!

You're right, twist arrows would have been helpful. It took me so long to install the battery because I removed the three tiny screws and then had a hell of a time getting the battery positioned while I put the screws back in. Also I think I've figured out that C,G,B,V, and U mean Cello, Guitar, Banjo, Violin, and Ukulele. It would have been nice to include that info on the instruction sheet. Oh well, what do you want for a buck?
