İlk Güç Açık

Basın ON button to turn on the calculator. The display should show a clear screen, ready for input. If the display is dim or blank, check the battery installation.

Kullanım Talimatları

Temel Hesaplamalar

Enter numbers and operations in the order they appear. For example, to calculate 5 + 3, press 5 + 3 =.

2 Satırlı Ekran

The top line of the display shows the entered expression, and the bottom line shows the result. This allows for easy review of your input.

Direct Algebraic Entry (DAE)

The calculator uses DAE, meaning you enter expressions in the same order as they are written mathematically, following standard order of operations (PEMDAS/BODMAS).

Accessing Secondary Functions

Many keys have a secondary function printed above them. To access these functions, press the 2. key (usually located in the top left) followed by the desired function key.

Hafıza Fonksiyonları

The calculator has 5 variable memories (A, B, C, D, E). To use them:

• Mağaza: Enter a value, press STO>, then press the variable key (e.g., A).
• Hatırlamak: Basmak RCL, then press the variable key (e.g., A).
• Temizlemek: To clear a specific memory, store 0 into it. To clear all memories, consult the calculator's on-screen menu or specific clear function if available.

Bilimsel İşlevler

The calculator includes standard scientific functions:

• Trigonometrik: sin, cos, tan, and their inverses (accessed via 2.). Ensure the correct angle mode (DEG, RAD, GRAD) is selected.
• Logaritmik: log, ln, and their inverses (10^x, e^x).
• Güçler ve Kökler: x², √, x^y, y√x.
• kesirler: Use the fraction key (a b/c) to enter and perform calculations with fractions.

Bakım

Temizlik

Wipe the calculator with a soft, dry cloth. Do not use abrasive cleaners or solvents, as they may damage the casing veya göster.

Pil Değişimi

Replace the battery when the display becomes dim or the calculator functions erratically. Refer to the "Battery Installation" section for detailed steps.

Depolamak

Store the calculator in a cool, dry place away from direct sunlight and extreme temperatures. If storing for an extended period, consider removing the battery to prevent leakage.

Sorun giderme

• Hesap makinesi açılmıyor:
  • Pilinin doğru takıldığından ve boşalmadığından emin olun. Gerekirse değiştirin.
  • Basın ON düğmeye sıkıca basın.
• Ekran loş veya boş:
  • Pili değiştirin.
  • Adjust display contrast if your model supports it (consult specific model documentation if available).
• Yanlış sonuçlar:
  • Check your input for errors.
  • Verify the correct angle mode (DEG, RAD, GRAD) is selected for trigonometric functions.
  • Clear all memory and reset the calculator (if a reset button or function is available, typically a small hole on the back requiring a paperclip).
• Tuşlar yanıt vermiyor:
  • Tuşların altında herhangi bir kalıntının kalmadığından emin olun.
  • Try pressing the key multiple times. If the issue persists, contact customer support.
