HP-48G clock mystery
Hi,
I recently bought my first HP-48G on eBay. It's showing some strange behavior. The clock only runs when it is switched on. You set the time correctly and then switch the calculator off. Later after powering on again, the HP-48G shows the time it was switched off. And continues counting from there. This of course also means that the alarm function is actually not usable either. What could be the reason and can it be fixed? |
