We have a 9910-080 UPS sitting around. I'd like to use it. Looked it up, as
much as I could, and it says it can be used for a 270 (originally for a
170). I've plugged it into the wall, ostensibly to charge it up. No lights,
nada. There's a sliding cover over a pushbutton, front upper-left corner.
Pressing that casues an LED to flash, then nothing.

How do I tell if it's usable?

Anyone have a manual? Or a link to one?

Thanks
