Enstalasyon
Sous pouvwa
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.
Enstalasyon batri / Ranplasman
- Asire w ke kalkilatris la etenn.
- Jwenn kouvèti konpatiman pil la sou dèyè kalkilatris la.
- Using a small screwdriver, carefully remove the screw securing the battery compartment cover.
- Retire kouvèti a.
- Remove the old LR44 battery (if replacing).
- Insert a new LR44 battery with the positive (+) side facing up.
- Ranplase kouvèti lòj batri a epi an sekirite li ak vis la.
Nòt: Dispose of used batteries according to local regulations. Do not mix old and new batteries.
Enstriksyon Operasyon
Limen / Off
- Peze a ON key to turn the calculator on.
- The calculator will automatically turn off after approximately 7-10 minutes of inactivity to conserve power.
Basic Arithmetic Calculations
- Adisyon: Antre premye nimewo a, peze +, antre dezyèm nimewo a, peze =.
- Soustraksyon: Antre premye nimewo a, peze -, antre dezyèm nimewo a, peze =.
- Miltiplikasyon: Antre premye nimewo a, peze ×, antre dezyèm nimewo a, peze =.
- Divizyon: Antre premye nimewo a, peze ÷, antre dezyèm nimewo a, peze =.
Pousantage Kalkil
Pou kalkile yon pousantajtage of a number (e.g., 10% of 200):
- Antre 200.
- Peze ×.
- Antre 10.
- Peze %. The result (20) will be displayed.
Fonksyon memwa
- M+: Ajoute valè ki parèt la nan memwa a.
- M-: Soustrè valè ki parèt la nan memwa a.
- RM (Recall Memory): Recalls the value stored in memory to the display.
- CM (Clear Memory): Clears the memory content. Pressing RM after CM will display 0.
Kalkil taks
The calculator features dedicated keys for tax calculations. First, set the tax rate:
- Peze TAS SET.
- Enter the tax rate (e.g., 5 for 5%).
- Peze SET.
To perform tax calculations:
- +TAX: Ajoute taks sou valè ki parèt la.
- -TAX: Soustrè taks nan valè ki parèt la.
Antretyen
- Netwayaj: Siye kalkilatris la avèk yon twal mou epi sèk. Pa sèvi ak pwodui netwayaj abrazif oswa solvan.
- Depo: Sere kalkilatris la nan yon kote ki fre epi sèk, lwen limyè solèy dirèk ak tanperati ekstrèm.
- Batri: If the calculator is not to be used for an extended period, remove the battery to prevent leakage.
- Evite enpak: Protect the calculator from drops and strong impacts.
Depanaj
| Pwoblèm | Solisyon |
|---|---|
| Ekran an vid oswa li fèb. | Ensure sufficient light for solar power. Replace the LR44 battery if necessary. |
| Rezilta kalkil ki pa kòrèk. | Peze CA to clear all entries and memory, then re-enter the calculation. Check for correct key presses. |
| Kle yo pa reponn. | Check battery power. Clean around keys if debris is present. Avoid operating in extreme temperatures. |
| "E" or "Error" displayed. | Indicates an overflow or mathematical error (e.g., division by zero). Press CA klè. |
