Setup

Izvor napajanja

The Sharp EL-250S calculator operates on a dual power system: solar power and a single LR44 button cell battery. In well-lit conditions, the calculator primarily uses solar power. In dim lighting or when solar power is insufficient, it automatically switches to battery power.

  2. Pronađite poklopac odjeljka za baterije na stražnjoj strani kalkulatora.
  3. Using a small screwdriver, carefully remove the screw securing the battery compartment cover.
  4. Skinite poklopac.
  5. Remove the old LR44 battery (if replacing).
  6. Umetnite novu LR44 bateriju s pozitivnom (+) stranom okrenutom prema gore.
  7. Vratite poklopac odeljka za baterije i pričvrstite ga vijkom.

Napomena: Dispose of used batteries according to local regulations. Do not mix old and new batteries.

  • The calculator will automatically turn off after approximately 7-10 minutes of inactivity to conserve power.

Osnovni aritmetički proračuni

  1. dodatak: Unesite prvi broj, pritisnite +, unesite drugi broj, pritisnite =.
  2. oduzimanje: Unesite prvi broj, pritisnite -, unesite drugi broj, pritisnite =.
  3. množenje: Unesite prvi broj, pritisnite ×, unesite drugi broj, pritisnite =.
  4. divizija: Unesite prvi broj, pritisnite ÷, unesite drugi broj, pritisnite =.

Percentage Proračuni

Za izračunavanje procentatage of a number (e.g., 10% of 200):

  1. Unesite 200.
  2. Pritisnite ×.
  3. Unesite 10.
  4. Pritisnite %. The result (20) will be displayed.

Memorijske funkcije

  • M+: Dodaje prikazanu vrijednost u memoriju.
  • M-: Oduzima prikazanu vrijednost iz memorije.
  • RM (Recall Memory): Vraća na ekran vrijednost pohranjenu u memoriji.
  • CM (Clear Memory): Clears the memory content. Pressing RM after CM will display 0.

Obračun poreza

The calculator features dedicated keys for tax calculations. First, set the tax rate:

  1. Pritisnite RATE SET.
  2. Enter the tax rate (e.g., 5 for 5%).
