Press the RESET switch (on the back) only in the following cases: · · · · When using for the first time After replacing the batteries To clear all memory contents When an abnormal condition occurs and all keys are inoperative. Editing the Equation · Press < or > to move the cursor. To return to the equation after getting an answer, press < (>). · To delete a number, place the cursor on the number to be deleted, then press d. [. . . ] The first part consists of a regular decimal number between 1 and 10. The second part represents how large or small the number is in powers of 10. While a calculation result is displayed in the floating point system, press @´ to display the result in the scientific notation system. Pressing @´ once again will bring back the floating point system. To enter a number in scientific notation, press E.
