Impressed by your battery salvaging skills, CB. I once took apart my bicycle. After I put it back together, I found three or four pieces that didn’t seem to have anywhere to go. That was my last attempt at tinkering!
Thanks for your suggestions about the speaker. I had figured out the ‘holding down the plus and minus buttons’ to control volume. Sadly, my King Won model does not have a play button. The other two buttons are Mode and Mute. The only way I can turn off those crazy lights is by standing the thing on its head. That stops the lights flashing in my eyes but battery power is still being wasted. The Chinese are crazy!
