3. Upute za rad

3.1. Osnovni izračuni

To perform basic arithmetic operations, simply input the numbers and operators in sequence. Press = da se dobije rezultat.

• Dodatak: [Number] + [Number] =
• Oduzimanje: [Number] - [Number] =
• Množenje: [Number] × [Number] =
• Podjela: [Number] ÷ [Number] =

3.2. Znanstvene funkcije

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

• Trigonometrijske funkcije: Koristiti grijeh, cos, preplanuli ten. For inverse functions, press POMJENA then the respective key (e.g., POMJENA + grijeh for sin^-1).
• Logaritamske funkcije: Koristiti log (baza 10) i ln (prirodni logaritam).
• Moći i korijeni: Koristiti x², x³, √ (square root). For other roots or powers, use POMJENA with relevant keys.
• Kutne jedinice: Pritisnite NAČIN RADA 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.

• Trgovina: Input a value, then press OPD followed by the desired memory key (e.g., A).
• Podsjetiti: Pritisnite RCL followed by the desired memory key to recall the stored value.
• Memory Plus/Minus: Koristiti M+ to add the displayed value to memory M, and POMJENA + M+ (M-) to subtract.

3.4. Statistical Calculations

Za ulazak u statistički način rada pritisnite NAČIN RADA 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. Podešavanje svjetline zaslona

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

4.3. Zamjena baterije

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. Rješavanje problema

• Kalkulator se ne uključuje:
  • Osigurajte dovoljno svjetla za solarni panel.
  • Check if the LR44 battery needs replacement.
  • Pritisnite tipku ON key firmly.
• Zaslon je taman ili prazan:
  • Increase ambient light for solar power.
  • Zamijenite bateriju LR44.
  • Adjust display brightness settings (refer to section 3.5).
• Netočni rezultati izračuna:
  • 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 POMJENA + CLR (Način 3).
• Tipke ne reagiraju:
  • Pazite da se ispod tipki ne zaglave ostaci.
  • Clean the calculator surface.
