To access functions printed in orange above the key, press @ first. Numbers are not shown as keys, but as ordinary numbers. Power On and Off Press N to turn the calculator on, and @ F to turn it off. Operational Notes To ensure trouble-free operation, observe the following points: 1. Do not carry the calculator in the back pocket of slacks or trousers. Do not subject the calculator to extreme temperatures. [. . . ] By using the modify function, the internal value is converted to match that of the display, so that the displayed value can be used without change in subsequent operations. 5÷9=ANS ANS×9= [FIX, TAB=1] N@f@i 1 5/9= * 9 =*1 5 / 9 =@j * 9 =*2 @f@f@f 0. 6 5. 0 0. 6 5. 4 *1 5. 55555555555×10­1×9 *2 0. 6×9 SIMULATION CALCULATION To obtain a result consecutively using the same formula, such as plotting a curve line for 2x2 + 1, or finding the variable for 2x + 2y =14, simply specify a new value for each variable in the formula.

STATISTICAL CALCULATIONS Statistical calculations are performed in the statistics mode. This calculator performs the seven statistical calculations indicated below. [. . . ] (This is the same for yx, x¿ y, n!, ex, In, etc. where continuous calculations are performed internally. ) Additionally, a calculation error will accumulate and become larger in the vicinity of inflection points and singular points of functions. (for example, calculating sinh x or tanh x at x = 0) · Calculation ranges ±10-99 ~ ±9. 999999999×1099 and 0. If the absolute value of an entry or a final or intermediate result of a calculation is less than 10­99, the value is considered to be 0 in calculations and in the display.
