2. Орнотуу

2.1 Кубат булагы

The TI-30Xa calculator operates on a single Lithium Metal battery. It also features a solar panel for extended battery life and operation in well-lit environments. Ensure the battery is properly installed before first use.

2.2 Баштапкы күйгүзүү

Калькуляторду иштетүү үчүн басыңыз ON/C button located in the upper right corner of the keypad. The display should show '0'. If the display remains blank, check the battery installation or ensure sufficient light for solar operation.

3. Иштөө нускамалары

This section covers the fundamental operations and functions of your TI-30Xa calculator.

3.1 Негизги арифметикалык амалдар

• Кошумча: Биринчи санды киргизиңиз, басыңыз +, экинчи санды киргизип, анан басыңыз =.
• Кемитүү: Биринчи санды киргизиңиз, басыңыз -, экинчи санды киргизип, анан басыңыз =.
• Көбөйтүү: Биринчи санды киргизиңиз, басыңыз x, экинчи санды киргизип, анан басыңыз =.
• Бөлүм: Биринчи санды киргизиңиз, басыңыз ÷, экинчи санды киргизип, анан басыңыз =.

3.2 Илимий функциялар

The calculator supports various scientific and trigonometric functions. Many functions have a secondary operation accessed by pressing the 2nd биринчи ачкыч.

• Trigonometric Functions (SIN, COS, TAN): Enter the angle value, then press the desired trigonometric function key. For inverse functions (SIN^-1, COS^-1, TAN^-1), басыңыз 2nd андан кийин функция баскычы.
• Logarithmic Functions (LOG, LN): Номерди киргизип, анан басыңыз LOG (base 10) or LN (natural logarithm). For 10^x or e^x, басыңыз 2nd андан кийин тиешелүү ачкыч.
• Powers and Roots (x², √x, y^x): Колдонуу x² квадраттоо үчүн, √x for square root. For general powers (y^x), enter the base, press y^x, көрсөткүчтү киргизип, анан басыңыз =.

3.3 Fraction Calculations

The TI-30Xa allows for direct input and calculation with fractions.

• Entering Fractions: колдонуу a^b/_c key. For mixed numbers, enter the whole number, press a^b/_c, санды киргизиңиз, басыңыз a^b/_c again, then enter the denominator. For simple fractions, enter the numerator, press a^b/_c, андан кийин бөлүүчүнү киргизиңиз.
• Converting Fractions/Decimals: Басыңыз F↔D to convert between fraction and decimal formats.

3.4 Конверсиялар

The calculator can perform various unit conversions.

• Angle Unit Conversion (DRG): Басыңыз DRG repeatedly to cycle through Degree (DEG), Radian (RAD), and Grad (GRAD) modes. The current mode is indicated on the display.
• DMS to Decimal Degrees (DMS↔DD): Enter a value in Degrees/Minutes/Seconds format, then press 2nd артынан DMS↔DD to convert to decimal degrees. Press again to convert back.

4. Техникалык тейлөө

Proper care will ensure the longevity and performance of your calculator.

• Тазалоо: Use a soft, dry cloth to clean the calculator. Do not use abrasive cleaners or solvents.
• Батареяны алмаштыруу: When the display becomes dim or erratic, it's time to replace the battery. Refer to the battery compartment on the back of the calculator for instructions. Ensure the calculator is off before replacing the battery.
• Сактагыч: Калькуляторду күн нурунан жана экстремалдык температурадан алыс салкын, кургак жерде сактаңыз.

5. Кыйынчылыктарды

If you encounter issues with your TI-30Xa, try the following solutions:

• Калькулятор күйбөйт: Check the battery. Ensure it is properly inserted and has sufficient charge. If operating in low light, move to a brighter area for solar power.
• Display shows 'Error': This indicates an invalid operation or a mathematical error (e.g., division by zero, square root of a negative number). Press ON/C to clear the error and re-enter your calculation.
• Unexpected results: Ensure the correct angle mode (DEG, RAD, GRAD) is selected for trigonometric calculations. Clear any previous calculations or memory by pressing ON/C эки жолу.
