On the bottom of the unit, there are 2 black things that look like buttons or something.
Run your thumb across it to find the hole.Ģ. There are 4 visible screws in the corners (if you can't see them, turn the unit over) and there is one in the middle under the NOMA sticker. There were no error codes or other messages, and I could display the power remaining by holding down that button.īefore you start, make sure the unit is in it's 'off' state and not plugged into the wall.ġ. My problem, just so you know, is that my Noma Backup Power 400 would not turn on. Back to working just like it did when it was new. What I did was open the unit, disconnect the batteries (just the black terminals), let it sit for 10 minutes and then reconnect it. I'm not responsible for you, but you are.
Take it to someone that knows how, and don't get yourself killed.
If you are not familiar with electronics - especially high-current stuff like this - I would advise you not to attempt this. And I'll tell how, just for anyone else that comes across this in future.
