E-2 Safety Precautions Be sure to read the follo wing safety precautions before using this calculator. Keep this man ual handy f or later reference. Caution This symbol is used to indicate information that can result in personal injury or material damage if ignored.
E-3 • The displa ys and illustr ations (such as ke y markings) shown in this User’ s Guide are f or illustr ativ e pur poses only , and ma y differ somewhat from the actual items they represent. • The contents of this manual are subject to change with- out notice.
E-4 Ta ke care ne ver to lea ve the calculator where it might be splashed b y w ater or e xposed to large amounts of hu- midity or dust. Such conditions can damage internal cir- cuitr y . • Never drop the calculator or otherwise subject it to strong impact.
E-5 Contents Safety Precautions .................................. 2 Handling Precautions ............................. 3 Tw o-line Display ...................................... 7 Before getting started... .......................... 7 k Modes .......

E-7 The two-line displa y makes it possible to view both the calculation formula and its result at the same time. • The upper line shows the calculation formula. • The lower line shows the result. A separator symbol is displayed every three digits when the integer part of the mantissa has more than three dig- its.
E-8 Note! •T o retur n the calculation mode and setup to the initial def aults shown below, press A B 2 (Mode) = . Calculation Mode: COMP Angle Unit: Deg Exponential Display Format: Norm 1 Fraction Display Format: a b / c Decimal Point Character: Dot • Mode indicators appear in the upper par t of the displa y .
E-9 k Replay Function • Every time you perform a calculation, the replay function stores the calculation formula and its result in replay memory . Pressing the [ ke y d isplays the f or m ula and result of the calculation you last performed. Pressing [ again back steps sequentially (new-to-old) through past calculations.
E-10 k Exponential Display Formats This calculator can display up to 10 digits. Larger values are automatically displayed using exponential notation. In the case of decimal values, you can select between two formats that determine at what point exponential notation is used.

E-22 SD REG SD Statistical Calculations Standard Deviation Use the F key to enter the SD Mode when you want to perform statistical calculations using standard de- viation. SD ................................................................... F 2 •A lways start data input with A B 1 (Scl) = to clear statistical memor y .
E-23 • S S inputs the same data twice. •Y ou can also input multiple entries of the same data using A G . To input the data 110 ten times, for e xample , press 110 A G 10 S . •Y ou can perf or m the abov e ke y oper ations in an y order, and not necessarily that shown above.
E-24 Press 2 to exit data input without registering the value you just input. Press 1 if you want to register the value you just input, without saving it in memor y . If you do this, ho we ver, y ou will not be able to display or edit any of the data you have input.
E-25 •A lways start data input with A B 1 (Scl) = to clear statistical memor y . •I nput data using the k e y sequence sho wn below. < x -data> P < y -data> S •T he values produced by a regression calculation depend on the values input, and results can be recalled using the k e y operations shown in the table below .
E-26 • The values in the above tables can be used inside of expressions the same way you use variables. u Linear Regression • The regression formula for linear regression is: y = A + B x .

E-29 Math ERROR •C auses • Calculation result is outside the allowable calculation range. • An attempt to perform a function calculation using a value that exceeds the allowable input range. • An attempt to perform an illogical operation (division by zero, etc.
E-30 k Order of Operations Calculations are performed in the following order of prec- edence. 1 Coordinate transf or mation: Pol ( x , y ), Rec ( r , θ ) 2 Ty pe A functions: With these functions, the value is entered and then the function key is pressed.
E-31 k Stacks This calculator uses memory areas, called “stacks,” to tem- porarily store values (numeric stack) and commands (com- mand stack) according to their precedence during calcu- lations. The numer ic stac k has 10 le v els and the command stack has 24 le vels.
