[. . . ] DISPLAY Appears in the display when the entire equation or the answer cannot be displayed. Appears in the display when [2ndF] is pressed, indicating that the functions written in blue on the calculator are enable. hYP Indicates that [hyp] has been pressed and the hyperbolic functions are enabled. If [2ndF] [hyp] are pressed, the symbols "2ndF HYP" appear, indicating that inverse hyperbolic functions are enabled. [. . . ] it remembers the entered equation as a formula. After finding the first answer, press 2ndF [?] and this function automatically moves the cursor back to the first number of the equation and lets you change the number. After that, you can skip to the next number by pressing 2ndF [?At any place, pressing [=] lets you know the answer for the new equation. Before starting calculations, specify the angular unit (See page 18) · Chain calculations(The result of the last calculation is used as the first operand. ) Random Number A pseudo-random number with three significant digits can be generated by pressing 2ndF [Random] = . To generate the next random number, press [=]. You can perform this function in the normal and statistics mode. Each random number is generated on the basis of the value stored in memory Y (pseudo-random number series) Angular Unit Conversions ( page 9) The angular unit can be changed in the following sequence: degreesradiansgradesdegrees. Memory Calculations ( page 8) This calculator has one independent memory (M), one last answer memory, and two temporary memories, (X, Y). Independent memory (M) (M) memory is available in the normal mode. STO [M] : Clear the independent memory and then stores the displayed value in it. STO [X], [Y] : Stores the displayed value in the specified temporary memory (X, Y) RCL [X], [Y] or 2ndF [ALPHA] [X], [Y] = : Recalls the value stored in the memory corresponding to the alphabetic key pressed. Temporary memory contents are cleared when the mode is changed or the value 0 is stored. Last answer memory The last answer memory is available in the normal and statistics mode. The calculation result obtained by pressing = or any other calculation ending instruction is automatically stored in the answer memory. 2ndF [ANS] : Recalls the contents of the last answer memory. Last answer memory is cleared when the mode is changed. Note: Calculation results from the functions indicated below are automatically stored in memories X or Y. For this reason, when using these functions, be careful with the use of memories X and Y. X memory, Y memory Fractions Calculations ( page 9) a b/c Key is used to enter a fraction or to convert a fraction to the decimal scale. [. . . ] The calculation ranges on page 18 were exceeded while performing function calculations or statistical calculations. Turn the power off by pressing 2ndF [OFF]. Install two new batteries and make sure the "+" side facing up. If the display does not appear as shown, remove the batteries reinstall DEG them and check the display once again. [. . . ]
