[. . . ] If service should be required on this calculator, use only a SHARP servicing dealer, SHARP approved service facility, or SHARP repair service where available. (During actual use not all symbols are displayed at the same time. ) If the value of mantissa does not fit within the range ±0. 000000001 ­ ±9999999999 , the display changes to scientific notation. [. . . ] A pseudo-random number with three significant digits can be generated by pressing @ `. Random number generation is not possible when binary/octal/hexadecimal system mode is set. Each time @ g are pressed, the angular unit changes in sequence. This calculator has one independent memory (M). The independent memory is indicated by the three keys: O, R, ;. Before starting a calculation, clear the memory by pressing ª and O. A value can be added to or subtracted from an existing memory value. When subtracting a number from the memory, press ± and ;. The contents of the memory are retained even when the calculator is turned off. A value stored in memory will thus remain until it is changed or until the batteries run out. This calculator allows the previous calculation result to be used in the following calculation. The previous calculation result will not be recalled after entering multiple instructions. In addition, the four basic arithmetic operations and memory calculations can be carried out using the sexagesimal system. This calculator can perform the four basic arithmetic operations, calculations with parentheses and memory calculations using binary, octal, decimal, and hexadecimal numbers. When performing calculations in each system, first set the calculator in the desired mode before entering numbers. It can also perform conversions between numbers expressed in binary, octal, decimal and hexadecimal systems. Conversion to each system is performed by the following keys: Ï ê : Converts to the binary system. Conversion is performed on the displayed value when these keys are pressed. Note: In this calculator, the hexadecimal numbers A ­ F are entered by pressing E, TM, /, ´, I, and l, and displayed as follows: When a decimal number having a fractional part is converted into a binary, octal, or hexadecimal number, the fractional part will be truncated. To carry out addition, subtraction, multiplication, and division using complex numbers, press @ to select the complex number mode. [. . . ] Keep batteries out of the reach of children. Exhausted batteries left in the calculator may leak and damage the calculator. Do not throw batteries into a fire as they may explode.
