- If the display does not appear, ensure adequate lighting for the solar panel or consider potential battery issues (refer to the Troubleshooting section).
Imiyalelo yokusebenza
This section details the functions of the keys and how to perform various calculations.
Basic Arithmetic Operations
- Ukwengeza (+): Faka inombolo yokuqala, cindezela +, faka inombolo yesibili, bese ucindezela =.
- Ukukhipha (-): Faka inombolo yokuqala, cindezela -, faka inombolo yesibili, bese ucindezela =.
- Ukuphindaphinda (×): Faka inombolo yokuqala, cindezela ×, faka inombolo yesibili, bese ucindezela =.
- Isigaba (÷): Faka inombolo yokuqala, cindezela ÷, faka inombolo yesibili, bese ucindezela =.
Clear Functions
- C (Clear Entry): Clears the last entered number or the current calculation entry without affecting previous operations or memory.
- CA (Clear All): Clears all entries, operations, and memory, resetting the calculator to its initial state.
- VALIWE: Turns the calculator off. The calculator also has an auto-power off feature to conserve energy.
Inkumbulo Imisebenzi
- I-M+ (I-Memory Plus): Ingeza inani elibonisiwe kwimemori.
- M- (Memory Minus): Isusa inani elibonisiwe kwimemori.
- RM (Recall Memory): Displays the current value stored in memory.
- CM (Clear Memory): Isula inani eligcinwe kumemori.
Imisebenzi ekhethekile
- % (Amaphesentitage): Kusetshenziselwa amaphesentitage izibalo. Okwesiboneloample, to calculate 10% of 200: enter 200, press ×, faka u-10, cindezela %.
- √ (Impande yesikwele): Calculates the square root of the displayed number. Enter a number, then press √.
- I-GT (Isamba Esiphelele): Accumulates the results of all calculations performed since the last CA or GT press. Press GT ukubonisa isamba esiphelele.
- MU (Mark-Up): Used for mark-up calculations. For example, to calculate the selling price with a 20% mark-up on a cost of 100: enter 100, press MU, faka u-20, cindezela =.
Isondlo
Ukuhlanza
Ukugcina ukubukeka nokusebenza kwesibali:
- Wipe the calculator's surface with a soft, dry cloth.
- Ngokungcola okunenkani, kancane dampen the cloth with water and mild soap, then wipe dry immediately.
- Do not use abrasive cleaners, solvents, or spray directly onto the calculator.
Isitoreji
Store the calculator in a cool, dry place away from direct sunlight and extreme temperatures when not in use for extended periods.
Ukuxazulula inkinga
If you encounter issues with your Sharp EL-122N-BK calculator, refer to the following common problems and solutions:
| Inkinga | Imbangela Engenzeka | Isixazululo |
|---|---|---|
| Isibonisi asinalutho noma sifiphele. | Insufficient light for solar panel; low battery. | Move the calculator to a brighter area. If the problem persists, the battery may need replacement (consult a service professional if necessary). |
| Imiphumela yokubala engalungile. | Incorrect key entry; calculator in an unusual state. | Cindezela CA to clear all operations and memory, then re-enter the calculation carefully. |
| Okhiye abaphenduli. | Dust or debris under keys; calculator malfunction. | Gently clean around the keys. If the issue persists, the calculator may require service. |
