Page 4: Safety Information
Safety Information It is essential to read the following safety information before starting to use the calculator. Keep this guide close to hand for reference later. Intended use This calculator serves exclusively for completing arithmetical processes indoors. Any other use is considered unintended use. Batteries After having removed the batteries from the calculator, keep them in a safe place so that they cannot get into the hands of small children... -

care when removing batteries which have already begun to leak from the device. Attention: Risk of caustic burns! Disposal is free of charge. The symbols indicate that the batteries must not be disposed of in normal domestic waste and that they must be brought to collection points provided by local public waste authorities. -
Page 6: Two-Line Display
Two-line Display The two-line display enables the simultaneous display of calculation equation and result. The top line displays the calculation equation. The bottom line displays the result. A separator appears after each third digit when the integer part of the mantissa is more than three digits. -
Page 7: Input Capacity
The mode indicator appears in the top section of the display. It is essential to check the current calculation mode (SD, REG, COMP) and angle unit setting (Deg, Rad, Gra) before beginning a calculation. Input capacity The memory area for entering calculations can record 79 steps. One step is recorded each time a digit key is pressed or an arithmetic operation key ( ) is pressed. -

Page 27: Order Of Priority Of Operations
Action Press the key to display the location of the error and then complete the corrective measures necessary. Arg ERROR Cause Incorrect use of an arguments. Action Press the key to display the location of the error and then complete the corrective measures necessary. Order of priority of operations The calculation operations are completed according to the following order of priority. -
Page 28: Stacks
If a calculation contains an argument which is a negative number, the negative number must be enclosed in parentheses. The negative sign () is treated as a type B function so that special care must be taken when the calculation contains a type A function with high priority or power or root operations. -

digit.) The errors are cumulative in the case of consecutive calculations and, therefore, could be large. (This also applies to internal consecutive , nPr, nCr calculations that are performed in the case of y, x!, etc., for example.) In the vicinity of the singular point of a function and point of inflection, errors are cumulative and may become large. -
