2. Seadistamine ja esmane kasutamine

2.1 Toiteallikas

The EL-531TG-GY calculator operates using both solar power and a single LR44 button cell battery. The solar panel provides power in well-lit environments, while the battery ensures operation in low-light conditions or when solar power is insufficient. An LR44 battery is included with the calculator.

2.2 Sisse/välja lülitamine

• Kalkulaatori sisse- ja väljalülitamiseks ON, vajutage nuppu ON/C võti.
• Kalkulaatori sisse- ja väljalülitamiseks VÄLJAS, vajutage nuppu 2. F klahv, millele järgneb VÄLJAS key (which is typically the same as ON/C).

2.3 Initial Display Settings

Upon first use or after a reset, the calculator will typically default to certain settings (e.g., DEG for angle units). Refer to Section 3.3 for details on changing mode settings.

3. Kasutusjuhised

3.1 Aritmeetika põhitehted

Sisestage numbrid numbriklahvistiku abil. Kasutage +, -, ×, ja ÷ keys for addition, subtraction, multiplication, and division, respectively. Press = to obtain the result.

3.2 Teaduslikud funktsioonid

The calculator performs over 273 advanced scientific functions. Many functions are accessed by pressing the 2. F key before the desired function key.

• Trigonomeetrilised funktsioonid: Kasutage patt, cos, tan. Inverse functions (patt⁻¹, sest⁻¹, päevitus⁻¹) are accessed via 2. F.
• Logaritmilised funktsioonid: Kasutage logi (alus 10) ja ln (naturallogaritm).
• Võimud ja juured: Kasutage x², √, x³, ³√.
• Murrud: Kasutage alalisvoolu key for fraction input and conversion.

3.3 Mode Settings (DEG/RAD/GRAD)

To change the angle unit mode (Degrees, Radians, Gradians):

1. Vajutage nuppu DRG võti.
2. Vajutage korduvalt DRG to cycle through DEG (Degrees), RAD (Radians), and GRAD (Gradians). The current mode is indicated on the display.

3.4 Mälufunktsioonid

Kalkulaatoril on mälufunktsioonid väärtuste salvestamiseks ja taasesitamiseks.

• STO (pood): Vajutage STO followed by a variable key (e.g., A, B) to store the displayed value.
• RCL (tagasikutsumine): Vajutage RCL followed by the variable key to recall the stored value.
• M+ (Memory Plus): Lisab kuvatud väärtuse sõltumatule mällu.
• M- (mälu miinus): Lahutab kuvatud väärtuse sõltumatust mälust.

3.5 Multi-Line Playback

The 2-line display allows for Multi-Line Playback, enabling users to review previous calculations and expressions. Use the directional arrow keys (up/down) to scroll through past entries and results. This feature is useful for checking work or re-using parts of previous calculations.

4. Hooldus

4.1 Puhastamine

To clean the calculator, wipe the surface gently with a soft, dry cloth. Do not use abrasive cleaners, solvents, or excessive moisture, as these can damage the display or internal components.

4.2 Aku vahetamine

The calculator uses one LR44 button cell battery. If the display becomes dim or erratic in low-light conditions, the battery may need replacement. To replace the battery:

1. Veenduge, et kalkulaator oleks välja lülitatud.
2. Leidke kalkulaatori tagaküljel olev patareipesa.
3. Avage ettevaatlikult sahtli kaas.
4. Eemaldage vana LR44 patarei ja sisestage uus, jälgides õiget polaarsust (+/-).
5. Sulgege akupesa kaas kindlalt.

4.3 Säilitamine

When not in use, store the calculator in a cool, dry place away from direct sunlight and extreme temperatures. The hard cover included with the calculator provides protection from scratches and minor impacts.

5. Veaotsing

5.1 Kuvamisprobleemid

• Tühi või hämar ekraan: Ensure sufficient light for the solar panel. If the issue persists, replace the LR44 battery.
• Erratic Display: This may indicate a low battery. Replace the LR44 battery.

5.2 Incorrect Results

• Check Mode Settings: Verify that the angle unit (DEG, RAD, GRAD) is set correctly for trigonometric calculations.
• Sisestusviga: Review your input using the Multi-Line Playback feature to ensure the expression was entered correctly.
• Memory Contents: If using memory functions, ensure the stored values are correct.

5.3 Kalkulaator ei reageeri

If the calculator becomes unresponsive, try performing a reset. Locate the RESET button (often a small recessed button requiring a thin object like a paperclip to press). Pressing this button will clear all memory and return the calculator to its factory default settings.
