Operational Notes
To ensure trouble-free operation, please 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.
_ 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.

INTRODUCTION
About operation examples, please refer to the attached sheet.
Refer to the number on the right of each title for use.
After reading this manual, store it in a convenient location for future reference. Note : One of the models described in this manual may not be available in some countries.
PERATION MANUAL
Mantissa Exponent
(During actual use not all symbols are displayed at the same time.)
/ : Appears when the entire equation cannot be displayed.
Press > to see the remaining (hidden) section.
xy/r: Indicates the mode of expression of results in the complex calculation mode.
2ndF : Appears when @ is pressed, indicating that the functions shown in orange are enabled.
ALPHA : Indicates that @ K or O (R) has been pressed, and entry (recall) of memory contents and recall 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.
: Appears when a simulation calculation is executed.
STAT : Appears when statistics mode is selected.
M :Indicates that a numerical value is stored in the independent memory.
? : Indicates that the calculator is waiting for a numerical value to be entered, such as during simulation calculation.
: Appears when the calculator shows an angle as the result in the complex calculation mode.
i : Indicates an imaginary number is being displayed in the complex calculation mode.
ALGB
Multi-line Playback function (1)
This calculator is equipped with a function to recall previous equations.
Equations also include calculation ending instructions such
as “=” and a maximum of 142 characters can be stored in memory.
When the memory is full, stored equations are deleted in the order of the oldest first. Pressing [ will display the previous equation.
Further pressing [ will display preceding equations (after returning to the previous equation, press ] to view equations in order). In addition, @[ can be used to jump to the oldest equation.
• The multi-line memory is cleared by the following operations:
@c, mode change, RESET, and N-base conversion.
For EL-546V, in addition to the above, pressing @F
(including the Automatic Power Off feature) will also clear the
multi-line memory.
Priority Levels in Calculation
This calculator performs operations according to the following priority:
1 ∠2 Functions preceded by their argument (x-1, x2, n!, etc.) 3
Yx, x. 4 Implied multiplication of a memory value (2Y, etc.) 5
Functions followed by their argument (sin, cos, etc.) 6 Implied
multiplication of a function (2sin30, etc.) 7 nCr, nPr 8 , ÷ 9 +, –
F AND G OR, XOR, XNOR H =, M+, M–, ⇒M, |DEG, |RAD,
|GRAD, DATA, CD, →r, →xy and other calculation ending instruction
• If parentheses are used, parenthesized calculations have precedence
over any other calculations.
SCIENTIFIC CALCULATIONS
• Press @ m 0 to select the normal mode.
• In each example, press a to clear the display. And if the FIX, SCI, or ENG indicator is displayed, clear the indicator by pressing
@ f.
Arithmetic Operations (2)
• The closing parenthesis ) just before = or ; may be omitted.
Constant Calculations (3)
• In the constant calculations, the addend becomes a constant.
Subtraction and division are performed in the same manner. For multiplications, the multiplicand becomes a constant.
• When performing calculations using constants, constants will be displayed as K.
Functions (4)
• Refer to operation examples of each function.
• Before starting calculations, specify the angular unit.
INITIAL SETUP
Mode Selection
Normal mode (NORMAL): @m0
Used to perform arithmetic operations and function calculations.
Complex number mode (CPLX): @m1
Used to perform arithmetic operations with complex numbers. 3-VLE mode (3-VLE): @m2
Used to perform simultaneous linear equations with three unknowns. Statistic mode (STAT): @m3
Used to perform statistical calculations.
When executing mode selection, temporary memories, statistical
data and last answer memory will be cleared even when reselecting
the same mode.
Selecting the Display Notation and Decimal Places
The calculator has four display notation systems for displaying calculation results. When FIX, SCI, or ENG symbol is displayed, the number of decimal places can be set to any value between 0 and 9. Displayed values will be reduced to the corresponding number of digits.
100000÷3=
[Floating point] a100000/3= 33333.33333
→[FIXed decimal point] @f 33333.33333
[TAB set to 2] @i 2 33333.33
→[SCIentific notation] @f 3.33104
→[ENGineering notation] @f 33.33103
→[Floating point] @f 33333.33333
• If the value for floating point system does not fit in the following
range, the calculator will display the result using scientific notation
system:
0.000000001 ≤| x | ≤9999999999
Determination of the Angular Unit
This calculator has three angular units: DEG (°), RAD (Radians)
and GRAD (g).
