6 Before Using the Calculator Check the current Calculation Mode Be sure to check the status indicators that indicate the current calculation mode (SD, REG... etc), display formats setting and angle unit setting (Deg, Rad, Gra) before starting a calculation. Return Calculation Mode to the initial setup Y ou can return the calculation mode to the in[...]

7 Input Capacity F-715SG allows you to input a single calculation up to 79 steps. Starting from the 73rd step, the cursor changes from [ _ ] to [ ] that notifying the memory is running low . In case you need to input a single calculation with more than 79 steps, you should separate your calculation into two or more segments. INPUTTING EXPRESSIONS A[...]

8 Input Editing New input begins on the left of the upper (entry) line. As the entries are more than 12 digits, the line will scroll to the right consecutively . Press , to scroll the cursor within the upper (entry) line and you can perform input editing as needed. (Example #2) • After deleting an input by or clearing the input by , icon will be [...]

9 INPUT RANGE AND ERROR MESSA GE Calculation Stacks This calculator uses memory areas, called "stacks", to temporarily store numeric value (numbers) and commands (+ – x ...) according to their precedence during calculations. The numeric stack has 10 levels and the command stack has 24 levels. A stack error [Stack ERROR] occurs whenever [...]

10 Calculation Stacks This calculator uses memory areas, called "stacks", to temporarily store numeric value (numbers) and commands (+ – x ...) according to their precedence during calculations. The numeric stack has 10 levels and the command stack has 24 levels. A stack error [Stack ERROR] occurs whenever you try to perform a calculati[...]
