Prior to initiating calculations
• This product uses a comma ‘,’ as a decimal separator; a period is used as a
thousand separator.
• Before performing any calculation, press @ @ ^ b to clear the
memory and the display.
• To start a calculation with a negative number, place a subtraction sign by
pressing - at the beginning of the calculation.
• If you wish to correct a wrong entry, press ! and re-enter the figure.
• In the calculation examples found in this section, indications and icons that may
appear on the screen (‘=’, ‘M+’, ‘M–’, ‘+’, ‘–’, ‘×’, and ‘÷’) are abbreviated or are
not shown.These icons appear to show you the interim result of calculations. For
example, the ‘=’ icon appears on the screen when = or % is pressed, while
icons such as ‘M+’ and ‘+’ appear after each corresponding key has been
pressed.
• An ‘M’ is shown when a value other than 0 is put in the memory.To clear the
content of the memory, press @ twice. Note that the pressing of $ or #
also functions as =.
• Press to enter ‘=’.To input ‘,’ (decimal separator), press .
• An error message ‘E’ is displayed if:
• the integer section of a calculation result exceeds 12 digits
• the memory exceeds 12 digits
• an attempt is made to divide a number by zero.
Press ! to clear the error condition.
