Flex Electronic Calculator Don’t Work
 

Hi All .. I’m at a lost .. First off I bought a flex calculator off eBay. it arrived went to set it up and I could not get any further then where it says change day. I sent it back and I ordered another one from eBay. The same thing happen with the second one. I’m wondering if it was possible when weight watchers changed the program did they or was there anyway that they could have made the older calculators stop functioning right. The calculator part works fine the adding and subtraction part. But how can they do that so they don’t work any longer? I’m Lost Thanks in advance for the options on this
