If you are charging your Jewelbot when it is completely dead, this step is unnecessary. Your Jewelbot will turn on automatically with a rainbow animation and then a red notification light.
If not, then make sure your Jewelbot is on when charging in order to get the red notification light.
Jewelbot can be turned on after charging for 5 minutes, but keep it plugged in and allow it to charge for longer. Just like a phone, the longer it’s charging the longer you will be able to use it.
