2. Fanombohana
2.1. Fametrahana bateria
The Sharp EL501X2BWH calculator operates on two LR44 batteries (included). To install or replace batteries:
- Ataovy azo antoka fa maty ny kajy.
- Tadiavo ao ambadiky ny kajy ny fonon'ny fitoeran'ny bateria.
- Remove the cover using a small screwdriver.
- Insert two new LR44 batteries, observing the correct polarity (+/-).
- Soloy tsara ny fonon'ny efitrefitra bateria.
Fanamarihana: Mampiasà bateria vaovao foana ary ariana amim-pahendrena ireo bateria efa tonta.
2.2. Mandehana sy miala
- Mba hamelomana ny kajy, tsindrio ny ON/C bokotra.
- Raha hamono ny kajy dia tsindrio ny F faharoa bokotra arahin'ny NIALA bokotra.
2.3. Asehoyview
The calculator features a 10-digit, 1-line LCD display. Indicators for various modes (e.g., DEG, RAD, GRAD, CPLX, STAT) will appear on the display to show the current calculator state.

3. Fampandehanana fototra
3.1. Arithmetic Calculations
Perform basic arithmetic operations using the number keys and the +, -, ×, ary ÷ fanalahidy. mpanao gazety = hanehoana ny vokatra.
- Example: Mba hikajiana 15 + 7: Tsindrio 1 5 + 7 =. Ny fampisehoana dia hampiseho 22.
3.2. Clear Functions
- mpanao gazety CE to clear the last entered number or operation.
- mpanao gazety ON/C to clear all entries and reset the calculator to its initial state (except memory).
4. Scientific Functions
The calculator provides 131 built-in functions. Many keys have secondary functions, accessed by pressing the F faharoa key before the desired function key.
4.1. Asa Trigonometrika
Ampiasao Ny fahotana, Kosy, tan for standard trigonometric calculations. Their inverse functions (Ny fahotana-1, Kosy-1, tan-1) dia azo idirana amin'ny alàlan'ny F faharoa.
The angle unit can be changed using the DRG fanalahidy. mpanao gazety DRG repeatedly to cycle through DEG (degrees), RAD (radians), and GRAD (gradients).
4.2. Logarithmic and Exponential Functions
- Logarithms: Ampiasao HIDITRA (fototra 10) ary ln (logarithma voajanahary).
- Exponentials: Ampiasao 10x (azo idirana amin'ny alalan'ny F faharoa SY HIDITRA) ary ex (azo idirana amin'ny alalan'ny F faharoa SY ln).
4.3. Powers and Roots
- Kianja: Ampiasao x2.
- Root efamira: Ampiasao √ (azo idirana amin'ny alalan'ny F faharoa SY x2).
- Hery ankapobe: Ampiasao yx.
- Reciprocal: Ampiasao 1/x (azo idirana amin'ny alalan'ny F faharoa SY yx).
4.4. Factorials
Calculate factorials using the n! function (accessed via F faharoa SY CPLX).
5. Fampiasa mandroso
5.1. N-Base Calculations (HEX, DEC, BIN, OCT)
The calculator supports calculations in different number bases: hexadecimal (HEX), decimal (DEC), binary (BIN), and octal (OCT). Use the dedicated keys for these operations, typically found above the number keys (e.g., →OCT, →BIN, →DEC, →HEX).

5.2. Complex Number Calculations
To enter and perform calculations with complex numbers, switch to Complex Mode. Press CPLX to activate this mode. The display will show "CPLX".
Refer to the calculator's key markings for specific complex number operations (e.g., real and imaginary part extraction, argument, magnitude).
5.3. Statistics Functions
The calculator supports one-variable statistical calculations. To enter Statistics Mode, press STAT. The display will show "STAT".
Ampiasao ny DATA CD key to clear statistical data and the M+ key to input data points. Statistical results (mean, standard deviation, etc.) can be retrieved using specific function keys, often accessed via F faharoa.
5.4. Fahatsiarovana Functions
The calculator has one independent memory. Use the following keys:
- M+: Manampy ny sanda aseho ao amin'ny fahatsiarovana.
- Što: Stores the displayed value into memory.
- RCL: Recalls the value from memory to the display.
6. Fikojakojana sy fikarakarana
6.1. Fanadiovana
To clean the calculator, wipe it with a soft, dry cloth. Do not use abrasive cleaners, solvents, or spray directly onto the calculator, as this may damage the casing na singa anatiny.
6.2. fitahirizana
When not in use, store the calculator in its protective hardcover to prevent scratches and damage. Avoid exposing the calculator to extreme temperatures, humidity, or direct sunlight for extended periods.

7. Famahana olana
7.1. Olana iraisana
- Tsy mandeha ny kajy: Hamarino tsara ny fametrahana ny bateria ary ataovy azo antoka fa tsy lany ny bateria. Soloy raha ilaina.
- "Error" message displayed: This usually indicates an invalid operation (e.g., division by zero, taking the square root of a negative number). Press CE or ON/C mba hanesorana ny lesoka sy hampidirana indray ny kajy.
- Vokatra diso: Verify that the correct mode (DEG/RAD/GRAD, Normal/Stat/Complex) is selected for your calculation. Ensure all previous calculations are cleared using ON/C before starting a new one.
7.2. Resetting the Calculator
If the calculator behaves erratically or freezes, a reset may resolve the issue. Locate the RESET button (a small recessed button, often requiring a thin object like a paperclip to press) on the back or front panel. Pressing this button will clear all memory and settings, returning the calculator to its factory default state.
