DM15L Problem
Hello all - I have a DM15L that suddenly stopped being able to go into RAD mode. Everything else seems to work. I have performed a reset as well as other key resets. When I do a power reset, I get PR ERROR. Any ideas?

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. |

Another thought... perhaps it's the annunciator that isn't working. Set RAD mode and try some trig functions on multiples of PI; maybe it is in RAD mode, but it isn't showing so?

Does GRAD appear if you set that mode? That uses the same annunciator area, with the G prepended.
Does the SCI function work, on the same key? Cambridge, UK 41CL/DM41X 12/15C/16C DM15/16 17B/II/II+ 28S 42S/DM42 32SII 48GX 50g 35s WP34S PrimeG2 WP43S/pilot/C47 Casio, Rockwell 18R |
