RE: DM15L Problem
"PR ERROR" is normal and it happens whenever the memory is cleared.
Run a keyboard test to ensure that all the keys are functioning correctly. Optionally, update the firmware for your model. We're up to V30 on that series of calculators. There are only 10 types of people in this world. Those who understand binary and those who don't. |
