Hi all,
i had programed my casio fx880p and used it for many years but somehow (maybe change of batteries) now i can not execute any program despite it indicates that still has programs in its memory(10 asterisks in basic mode). Is it possible to execute programs without losing them?
Calculator often fails, it puts asterisk in all programs and does not work well. It is able to do simple addition. If your calculator can not addition, you may not have the 10 programs have the error.
please confirm.
No i can not do any mathematic calculation. After typing 2 + 2 appears on screen : OM error
I guess you are right my machine has an error. Can you tell me how could i fix this problem?
Apart from making it calculate properly I want also to programme it again. I have the programms typped on a paper but i dont know how to start programming it again. As i told you before i can not do anything in basic mode. Is it easier to do this via pc? In that case i will need i cable and a software?
I have a programmable calculator Casio FX-702P. I need a help to reset the unit becausethe LCD Screen shows a continuous character moving from right to left. Any key buttom to reset or stop the problem? When the character moving stop, a number :89 :>,Z $ Z appear. THank you.
Thank you for your time and effort to answer my inquiry. I greatly appreciated that.I did the instructions given but it did not work. I do not know if I did it properly. I just notice the command F2 followed by T button refer DEFM in my calculator not DEFT.
Just changed all 3 batteries, first time after I got the FX880p new some 30 years ago. I measured them after replacing and all were showing 3V+. Most importantly, all is working great.
What I did was replace the small backup battery first, put it back firmly in place, then changed the 2 main ones. The big ones are more likely to retain some juice over time, and the small one is probably more likely to drain first. Hope someone might find this useful.
Hi I have been using casio fx-850p since many years.
I have loaded my program in casio fx-850p and it was working fine since few years. Suddenly, when I tried to open the program today, it started throwing FC error 5. Would you please help me on this error? I tried to reset but no luck
Hi javitopo
Thank you very much for quick response. I was trying to say that program was working since long and after starting my PC few days in the morning, it started throwing FC error. May be my son played with it:) Would you please tell me how can I open the program and debug line 5?
Yes. It is FX-850P. Thanks for the response. The program is in Calculator. When I did the edit and exe. it started giving me PR error.
By the way, when I entered into mode 1 (BASIC), it gives me P ******* 83338B. Is there any strange indication there? How can I move my calc program to PC?
