INTRODUCTION
After reading this manual, store it in a convenient location for future reference.

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. 2. Do not subject the calculator to extreme temperatures. 3. Do not drop it or apply excessive force. 4. Clean only with a soft, dry cloth. 5. Do not use or store the calculator where fluids can splash onto it. SHARP will not be liable nor responsible for any incidental or consequential economic or property damage caused by misuse and/or malfunctions of this product and its peripherals, unless such liability is acknowledged by law. � Press the RESET switch only in the following cases: � When using for the first time � After replacing the batteries � To clear all memory contents � When an abnormal condition occurs and all keys are inoperative. If service should be required on this calculator, use only a SHARP servicing dealer, SHARP approved service facility, or SHARP repair service where available.

Clearing Methods
There are three clearing methods as follows: Clearing operation N @c RESET : Clear � : Retain * Independent memory M.

Editing the Equation
� Press < or > to move the cursor. To return to the equation after getting an answer, press @ '. � To delete a number, move the cursor to the number to be deleted, then press d. The number under the cursor will be deleted. � To insert a number, move the cursor to the place immediately after where the number is to be inserted, then enter the number.

Priority Levels in Calculation DISPLAY
Equation Display Symbol This calculator performs operations according to the following priority: Q� W Functions preceded by their argument (x-1, x2, n!, etc.) E Yx, x¿ R Implied multiplication of a memory value (2Y, etc.) T Functions followed by their argument (sin, cos, etc.) Y Implied multiplication of a function (2sin30, etc.) U nCr, nPr I �, ÷ O +, � P AND { OR, XOR, XNOR } =, M+, M�, �M, |DEG, |RAD, |GRAD, DATA, CD, �rθ, �xy and other calculation ending instruction � If parentheses are used, parenthesized calculations have precedence over any other calculations.

Mantissa

Exponent

(All symbols will not be displayed simultaneously, as shown above.) / : Appears when the entire equation cannot be displayed. Press </> to see the remaining (hidden) section. xy/rθ 2ndF HYP : Indicates the mode of expression of results in the complex calculation mode. : Appears when @ is pressed, indicating that the functions shown in orange are enabled. : Indicates that h has been pressed, and the hyperbolic functions are enabled. If @H are pressed, the symbols �2ndF HYP� should appear, indicating that inverse hyperbolic functions are enabled.

INITIAL SETUP Mode Selection
Normal mode: m0 Used to perform arithmetic operations and function calculations. The pointer ��� appears below �0: NORMAL�. Complex number mode: m1 Used to perform arithmetic operations with complex numbers. The pointer ��� appears below �1: CPLX�. 3-VLE mode : m2 Used to perform simultaneous linear equations with three unknowns. The pointer ��� appears below �2: 3-VLE�. Statistic mode: m3 Used to perform statistical calculations. The pointer ��� appears below �3: STAT�. When executing mode selection, temporary memories, statistical data and last answer memory will be cleared even when reselecting the same mode.

ALPHA : Indicates that @ K or O (R) has been pressed, and entry (recalling) of memory contents and recalling of statistics can be performed. FIX/SCI/ENG: Indicates the notation used to display a value and changes each time @ f are pressed. DEG/RAD/GRAD: Indicates angular units and changes each time G is pressed.
ALGB

: Appears when a simulation calculation is executed. : Indicates that a numerical value is stored in the independent memory. : Indicates the operation mode. : Indicates that the calculator waits for a numerical value entry, such as during simulation calculation. : Appears when the calculator shows an angle as the result in the complex calculation mode.

M �

?

i

: Indicates an imaginary number is being displayed in the complex calculation mode.
