â¢ To clear all variables (M, A-F, X, Y, ANS, STAT VAR), press 00 or 0Â®. â¢ To RESET the calculator, press 10 or 1Â®. The RESET operation will erase all data stored in memory, and restore the calculator's default setting.
Entering and Correcting the Equation
[Cursor keys] â¢ Press < or > to move the cursor. You can also return to the equation after getting an answer by pressing > (<). See the next section for using the [ and ] keys. â¢ In the SET UP menu and other locations, use the < or > key to move the flashing cursor, then press Â® (= key). If you need to scroll up/down the view, use the [ or ] key.
âSymbol Equationâ Display
â¢ During actual use, not all symbols are displayed at the same time. â¢ Certain inactive symbols may appear visible when viewed from a far off angle. â¢ Only the symbols required for the usage under instruction are shown in the display and calculation examples of this manual.
[Insert mode and Overwrite mode in the Equation display] â¢ This calculator has two editing modes: insert mode (default), and overwrite mode. Pressing @â switches between the two modes. A triangular cursor indicates that an entry will be inserted at the cursor, while the rectangular cursor indicates to overwrite preexisting data as you make entries. â¢ To insert a number in the insert mode, move the cursor to the place immediately after where you wish to insert, then make a desired entry. In the overwrite mode, data under the cursor will be overwritten by the number you enter. â¢ This mode setting will be retained until the next RESET operation is executed. [Deletion key] â¢ To delete a number/function, move the cursor to the number/function you wish to delete, then press d. If the cursor is located at the right end of an equation, the d key will function as a back space key.
