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 Vern Hamberg Would you like to see a challenging little arithmetic puzzle that might get you or your kids or grandkids more interested in math?
