Why is my calculator frozen?


Is the cursor checkered? If so, there is no more space on the entry line. Use the DEL key to shorten it or clear it. Clear the RAM also.

My calculator keeps rounding to the tenths place, I read I need to go to mode and change a setting, but I cannot find mode?


I am describing the procedure for the CAS with OS version 2.1 But it should work for your calculator.

  1. Turn calculator ON
  2. Press The HOME (House icon) button.
  3. Press digit key 5 to open Settings and status.
  4. In menu options, select [2:Settings]
  5. Use the arrow (right) to open the submenu options and select [1:General]
  6. The cursor should be on drop down box labeled Display Digits
  7. Use down arrow to open the number display format, and select Float 6 (an appropriate choice most of the time. If you want more digits, set Float 12)
  8. Press [ENTER] or Click to validate your selection.
  9. The drop down box will close.
  10. Use the TAB button to move to another Configuration setting. Pressing the TAB twice will take you to Exponential format.
  11. Use down arrow to unfold the Exponential format menu.
  12. If you do not need Scientific Format, use Normal and validate.
  13. Press TAB several times until cursor reaches OK.
  14. At this point Press ENTER to save Configuration.
  15. This should solve the problem.

As I said, this describes the procedure for OS version 2.1. Once you find out how to enter the setting screen, do as I described above, and do not forget to validate by getting the cursor on OK and validate.

My calculator is completely non responsive. When I hit the on button, the calculator cursor comes up but does not blink or allow me to type anything in. I have to hold the on button to keep the cursor...


It sounds as if the batteries are dead. If you are having to hold the power button on to keep the cursor on the screen, that is because the batteries only have enough power to flash a cursor, holding the power key means that the flash is constant. Try changing the batteries, this should solve the problem.

I get ERR: DOMAIN everytime I try to inverse a matrix


  1. First, Press the "MATRX" button

  2. Next, enter a matrix into the calculator. To enter a matrix, press the arrow that points to the right two times when the cursor highlights letter "A." This moves the top cursor to "Edit." Press "Enter" to select the "Edit" option.

  3. Next,, enter the matrix's numbers into the matrix on the calculator. Press "Enter" to move the cursor over one column. Press a button that has a dash symbol within parenthesis [( - )] to move down one row. Repeat the steps until the matrix is completed.

  4. Next, Press "2nd" then "Mode" to go back to the home screen. Press "MATRX" to enter the matrix screen again.

  5. Finally, press "Enter" when the cursor highlights matrix "A" then press "[x^ -1]." Your screen should read "[A]^ -1." Press "Enter" again to display the inverse matrix.

Dell wireless mouse cursor froze in middle of screen.


Hi, my cursor had frozen on my screen after my grand daughter pressing something. After trying everything I decided to take it to a local computer shop, it was fixed in seconds. He held the arrow tab(below the caps lock tab) and then pressed F9 it worked!!
Hope this will fix your problem
