2. Darbo pradžia

2.1. Akumuliatoriaus įdėjimas

The Sharp EL501X2BWH calculator operates on two LR44 batteries (included). To install or replace batteries:

1. Įsitikinkite, kad skaičiuotuvas yra išjungtas.
2. Skaičiuoklės gale suraskite baterijų skyriaus dangtelį.
3. Remove the cover using a small screwdriver.
4. Insert two new LR44 batteries, observing the correct polarity (+/-).
5. Saugiai uždėkite akumuliatoriaus skyriaus dangtelį.

Pastaba: Visada naudokite naujas baterijas, o senas baterijas utilizuokite atsakingai.

2.2. Įjungimas ir išjungimas

• Norėdami įjungti skaičiuotuvą, paspauskite ON/C mygtuką.
• To turn off the calculator, press the 2-oji F mygtuką, po kurio eina IŠJUNGTA mygtuką.

2.3. Rodyti perview

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. Pagrindinės operacijos

3.1. Arithmetic Calculations

Perform basic arithmetic operations using the number keys and the +, -, ×, ir ÷ raktai. Paspauskite = kad būtų rodomas rezultatas.

• ExampLe: To calculate 15 + 7: Press 1 5 + 7 =. Ekrane bus rodoma 22.

3.2. Clear Functions

• Paspauskite CE to clear the last entered number or operation.
• Paspauskite ON/C to clear all entries and reset the calculator to its initial state (except memory).

4. Mokslinės funkcijos

The calculator provides 131 built-in functions. Many keys have secondary functions, accessed by pressing the 2-oji F key before the desired function key.

4.1. Trigonometric Functions

Naudokite nuodėmė, cos, įdegis for standard trigonometric calculations. Their inverse functions (nuodėmė^-1, cos^-1, įdegis^-1) are accessed via 2-oji F.

The angle unit can be changed using the DRG raktas. Paspauskite DRG repeatedly to cycle through DEG (degrees), RAD (radians), and GRAD (gradients).

4.2. Logarithmic and Exponential Functions

• Logaritmai: Naudokite žurnalas (10 bazė) ir ln (natūralusis logaritmas).
• Exponentials: Naudokite 10^x (pasiekiama per 2-oji F ir žurnalas) ir e^x (pasiekiama per 2-oji F ir ln).

4.3. Powers and Roots

• Kvadratas: Naudokite x².
• Kvadratinė šaknis: Naudokite √ (pasiekiama per 2-oji F ir x²).
• Bendra galia: Naudokite y^x.
• Reciprocal: Naudokite 1/x (pasiekiama per 2-oji F ir y^x).

4.4. Factorials

Calculate factorials using the n! function (accessed via 2-oji F ir CPLX).

5. Išplėstinės funkcijos

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".

Naudokite 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 2-oji F.

5.4. Atminties funkcijos

The calculator has one independent memory. Use the following keys:

• M+: Įtraukia rodomą reikšmę į atmintį.
• STO: Stores the displayed value into memory.
• RCL: Recalls the value from memory to the display.

6. Priežiūra ir priežiūra

6.1. Valymas

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 arba vidiniai komponentai.

6.2. Sandėliavimas

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. Problemų sprendimas

7.1. Dažnos problemos

• Skaičiuoklė neįsijungia: Patikrinkite baterijų įdėjimą ir įsitikinkite, kad jos nėra išsikrovusios. Jei reikia, pakeiskite baterijas.
• "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 , kad ištaisytumėte klaidą ir iš naujo įvestumėte skaičiavimą.
• Neteisingi rezultatai: 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.
