2. Asennus
2.1 Akun asennus
The Sharp EL-531TH calculator requires one AAA battery for operation. A battery is typically included with the product.
- Etsi laskimen takaa paristolokeron kansi.
- Liu'uta kansi pois nuolen osoittamaan suuntaan.
- Insert one AAA battery, ensuring the correct polarity (+/-) as marked inside the compartment.
- Sulje paristolokeron kansi, kunnes se napsahtaa tukevasti paikalleen.
2.2 Ensimmäinen käynnistys
Kun olet asentanut akun, paina ON/C key to turn on the calculator. The display should show "0" or a similar initial state. If the display does not appear, recheck the battery installation or replace the battery.

3. Käyttöohjeet
3.1 Peruslaskelmat
Enter numbers using the numeric keypad and perform operations using the +, -, ×, ÷ keys. Press = saadaksesi tuloksen.
Example: To calculate 15 + 7:
- Paina 1 5
- Paina +
- Paina 7
- Paina = (Tulos: 22)
3.2 Direct Algebraic Logic (D.A.L.)
The D.A.L. system allows you to input equations exactly as they are written. For example, to calculate sin(30):
- Ensure the calculator is in DEG (degrees) mode. (Press MODE then select DEG if needed).
- Paina synti
- Paina 3 0
- Paina = (Tulos: 0.5)
3.3 toimintonäppäintä
Many keys have secondary functions, accessed by pressing the 2. luokka key first. The secondary functions are typically printed above the primary key function.
Example: To calculate x² (square of a number):
- Enter the number, e.g., 5
- Paina x² (Tulos: 25)
Example: To calculate √x (square root of a number):
- Paina √
- Enter the number, e.g., 2 5
- Paina = (Tulos: 5)
3.4 Muistifunktiot
The calculator includes memory functions to store and recall values.
- STO: Stores the displayed value into a memory variable (A-F, X, Y, M).
- RCL: Recalls a value from a memory variable.
- M+: Adds the displayed value to the independent memory.
- M-CLR: Clears the independent memory.

4. Huolto
4.1 Puhdistus
Laskimen puhdistamiseen käytä pehmeää, kuivaa liinaa. Pinttyneeseen likaan, pyyhi kevyestiampKostuta liina vedellä ja miedolla pesuaineella ja pyyhi se sitten heti kuivaksi. Älä käytä hankaavia puhdistusaineita, liuottimia tai suihkuta ainetta suoraan laskimeen.
4.2 Pariston vaihto
When the display becomes dim or calculations are erratic, it is time to replace the battery. Follow the steps in Section 2.1. Ensure the calculator is turned off before replacing the battery.
4.3 Varastointi
Store the calculator in a cool, dry place, away from direct sunlight and extreme temperatures. Use the provided protective cover to prevent scratches and damage to the keys and display.
5. Vianmääritys
| Ongelma | Mahdollinen syy | Ratkaisu |
|---|---|---|
| Näyttö on tyhjä tai himmeä. | Akku on vähissä tai tyhjä; akun virheellinen asennus. | Vaihda AAA-paristo varmistaen oikean napaisuuden. |
| Virheelliset laskutulokset. | Incorrect mode setting (e.g., RAD instead of DEG); input error; memory error. | Check the mode setting (DRG key). Review input. Press RESET button (located on the back, requires a thin object like a paperclip) to clear all memory and settings. |
| Näppäimet eivät reagoi. | Calculator frozen; physical damage. | Paina ON/C. If unresponsive, press the RESET button. If problem persists, contact support. |
| "ERROR" message on display. | Mathematical error (e.g., division by zero, invalid function input). | Review your input and the mathematical operation. Press ON/C poistaaksesi virheen. |
