2. Tatūnga
2.1 Tāuta Pūhiko
The Sharp EL-531TH calculator requires one AAA battery for operation. A battery is typically included with the product.
- Kimihia te uhi o te wahanga pākahiko kei muri o te tatauranga.
- Pahekehia te taupoki kia puta i te ahunga e tohua ana e te pere.
- Insert one AAA battery, ensuring the correct polarity (+/-) as marked inside the compartment.
- Whakakapia te uhi o te wahanga pākahiko kia pao pai ki te waahi.
2.2 Hiko Tuatahi
I muri i te whakauru i te pākahiko, pehia te 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. Nga Tohutohu Whakahaere
3.1 Tatau Taketake
Enter numbers using the numeric keypad and perform operations using the +, -, ×, ÷ keys. Press = ki te tiki i te hua.
Example: To calculate 15 + 7:
- Perehi 1 5
- Perehi +
- Perehi 7
- Perehi = (Hunga: 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).
- Perehi hara
- Perehi 3 0
- Perehi = (Hunga: 0.5)
3.3 Kī Mahi
Many keys have secondary functions, accessed by pressing the Te Whare Tuarua 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
- Perehi x² (Hunga: 25)
Example: To calculate √x (square root of a number):
- Perehi √
- Enter the number, e.g., 2 5
- Perehi = (Hunga: 5)
3.4 Nga Mahi Mahara
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. Tiaki
4.1 Te horoi
Hei horoi i te tātaitai, whakamahia he kakahu ngohengohe, maroke. Mo te paru maro, paku dampen 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 Whakakapinga Pūhiko
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 Rokiroki
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. Te Raru
| Raruraru | Take pea | Rongoā |
|---|---|---|
| He putea, he atarua ranei te whakaaturanga. | He iti te pākahiko, kua mate rānei; he hē te tāutanga o te pākahiko. | Whakakapihia te pākahiko AAA, kia tika te polarity. |
| He he nga hua tatauranga. | Incorrect mode setting (e.g., RAD instead of DEG); input error; memory error. | Check the mode setting (DRG key). Review input. Press WHAKATURU button (located on the back, requires a thin object like a paperclip) to clear all memory and settings. |
| Ko nga taviri kaore e aro. | Calculator frozen; physical damage. | Perehi ON/C. If unresponsive, press the WHAKATURU 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 ki te whakakore i te hapa. |
