• To clear all memory contents • When an abnormal condition occurs and all keys are inoperative Do not use an object with a breakable or sharp tip. Note that pressing the RESET switch erases all data stored in memory.
Hard Case Remove the hard case, holding it with your fi ngers in the positions shown below. DISPLAY Symbol matrix display Mantissa Exponent • During actual use, not all symbols are displayed at the same time. • Only the symbols required for the usage currently being explained are shown in the display and calculation examples in this manual.
ALPHA: Indicates that ; , x or t has been pressed, and entry (recall) of memory contents and recall of statistics can be performed. DEG/RAD/GRAD: Indicates angular units. BUSY: Appears during the execution of a calculation. W-VIEW: Indicates that the WriteView editor is selected. Indicates that a numerical value is stored in the independent memory (M).
• Functions that are printed in gray adjacent to the keys are effective in specifi c modes. • The multiplication operator “×” is differentiated from the letter “X” in this manual as follows: To specify the multiplication operator: k To specify the letter “X”: ; X The WriteView and Line Editors This calculator has the following two editors in NORMAL mode: WriteView and Line.

For the former case, divide integral intervals as small as possible. For the latter case, separate the positive and negative values. Following these tips will allow you to obtain results from calculations with greater accuracy and will also shorten the calculation time. Performing differential calculations 1.
Note: Parameters are entered in the following way: WriteView editor: (function) – value of [, minute interval] Line editor: (function, value of [, minute interval]) ∑ Function ∑ function returns the cumulative sum of a given expression from an initial value to an end value in NORMAL mode.
