3. Əməliyyat Təlimatları

3.1. Əsas Hesablamalar

To perform basic arithmetic operations, simply input the numbers and operators in sequence. Press = nəticəni əldə etmək üçün.

• Əlavə: [Number] + [Number] =
• Çıxarma: [Number] - [Number] =
• Çoxalma: [Number] × [Number] =
• Bölmə: [Number] ÷ [Number] =

3.2. Elmi funksiyalar

The calculator supports 240 scientific functions. Many functions are accessed by pressing the SHIFT key before the desired function key (indicated by text above the key).

• Triqonometrik funksiyalar: istifadə edin günah, cos, tan. For inverse functions, press SHIFT then the respective key (e.g., SHIFT + günah for sin^-1).
• Loqarifmik Funksiyalar: istifadə edin log (10-cu baza) və ln (natural loqarifm).
• Güclər və Köklər: istifadə edin x², x³, √ (square root). For other roots or powers, use SHIFT with relevant keys.
• Angle Units: basın MODE multiple times to cycle through angle units (Degrees, Radians, Gradians).

3.3. Memory Calculations

The calculator includes 9 variable memories (A-F, X, Y, M) for storing and recalling values.

• Mağaza: Input a value, then press STO followed by the desired memory key (e.g., A).
• Xatırlayın: basın RCL followed by the desired memory key to recall the stored value.
• Yaddaş Artı/Mənfi: istifadə edin M+ to add the displayed value to memory M, and SHIFT + M+ (M-) to subtract.

3.4. Statistical Calculations

To enter statistical mode, press MODE and select the STAT option. Follow the on-screen prompts to input data and perform calculations such as standard deviation and regression analysis.

3.5. Ekran Parlaqlığının Tənzimlənməsi

The calculator features a brightness adjustment function to optimize visibility in different lighting conditions and reduce eye strain.

4.3. Batareyanın dəyişdirilməsi

When the display becomes dim or the calculator functions erratically, it may be time to replace the LR44 battery. Carefully open the battery compartment on the back of the calculator, replace the old battery with a new LR44 battery, ensuring correct polarity, and close the compartment securely.

5. Giderme

• Kalkulyator açılmır:
  • Ensure there is sufficient light for the solar panel.
  • Check if the LR44 battery needs replacement.
  • düyməsini basın ON key firmly.
• Ekran tutqun və ya boşdur:
  • Increase ambient light for solar power.
  • LR44 batareyasını dəyişdirin.
  • Adjust display brightness settings (refer to section 3.5).
• Yanlış hesablama nəticələri:
  • Verify the input values and operators.
  • Check the current calculation mode (e.g., DEG/RAD/GRA for angles).
  • Clear all memory and reset the calculator by pressing SHIFT + CLR (Rejim 3).
• Açarlar cavab vermir:
  • Açarların altında heç bir zibil qalmadığından əmin olun.
  • Clean the calculator surface.
