2. Uppsetning
2.1 Uppsetning rafhlöðu
The Sharp EL-531TH calculator requires one AAA battery for operation. A battery is typically included with the product.
- Finndu rafhlöðulokið aftan á reiknivélinni.
- Renndu hlífinni af í þá átt sem örin gefur til kynna.
- Insert one AAA battery, ensuring the correct polarity (+/-) as marked inside the compartment.
- Settu lokið á rafhlöðuhólfið aftur þar til það smellpassar.
2.2 Byrjunarkveikt
Eftir að rafhlaðan hefur verið sett í, ýttu á 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. Notkunarleiðbeiningar
3.1 Grunnútreikningar
Enter numbers using the numeric keypad and perform operations using the +, -, ×, ÷ keys. Press = til að fá niðurstöðuna.
Example: To calculate 15 + 7:
- Ýttu á 1 5
- Ýttu á +
- Ýttu á 7
- Ýttu á = (Niðurstaða: 22)
3.2 Bein algebruleg rökfræði (DAL)
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).
- Ýttu á synd
- Ýttu á 3 0
- Ýttu á = (Niðurstaða: 0.5)
3.3 aðgerðatakkar
Many keys have secondary functions, accessed by pressing the 2. flokkur 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
- Ýttu á x² (Niðurstaða: 25)
Example: To calculate √x (square root of a number):
- Ýttu á √
- Enter the number, e.g., 2 5
- Ýttu á = (Niðurstaða: 5)
3.4 Minnisvirkni
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. Viðhald
4.1 Þrif
Til að þrífa reiknivélina skal nota mjúkan, þurran klút. Fyrir þrjósk óhreinindi skal þurrka örlítið.ampen the cloth with water and a mild detergent, then wipe dry immediately. Do not use abrasive cleaners, solvents, or spray directly onto the calculator.
4.2 Skipt um rafhlöðu
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 Geymsla
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. Bilanagreining
| Vandamál | Möguleg orsök | Lausn |
|---|---|---|
| Skjárinn er auður eða dimmur. | Lítil eða dauð rafhlaða; röng uppsetning rafhlöðu. | Skiptu um AAA rafhlöðuna og gætið þess að hún snúi rétt. |
| Rangar útreikningsniðurstöður. | Incorrect mode setting (e.g., RAD instead of DEG); input error; memory error. | Check the mode setting (DRG key). Review input. Press ENDURSTILLA button (located on the back, requires a thin object like a paperclip) to clear all memory and settings. |
| Lyklarnir svara ekki. | Calculator frozen; physical damage. | Ýttu á ON/C. If unresponsive, press the ENDURSTILLA button. If problem persists, contact support. |
| Skilaboðin „VILLA“ birtast. | Mathematical error (e.g., division by zero, invalid function input). | Review your input and the mathematical operation. Press ON/C til að hreinsa villuna. |
