2. Asennus ja käyttöönotto

2.1 Virtalähde

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 Kytkeminen päälle/pois

• Laskimen kääntäminen ON, paina ON/C avain.
• Laskimen kääntäminen POIS, paina 2. luokka -näppäintä ja sen jälkeen POIS 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. Käyttöohjeet

3.1 Aritmeettisten peruslaskutoimitusten

Syötä numerot numeronäppäimistöllä. Käytä +, -, ×, ja ÷ keys for addition, subtraction, multiplication, and division, respectively. Press = to obtain the result.

3.2 Scientific Functions

The calculator performs over 273 advanced scientific functions. Many functions are accessed by pressing the 2. luokka -näppäintä ennen haluttua toimintonäppäintä.

• Trigonometriset funktiot: Käyttää synti, cos, rusketus. Inverse functions (synti⁻¹, koska, rusketus) pääsee käsiksi kautta 2. luokka.
• Logaritmiset funktiot: Käyttää loki (kantaluku 10) ja ln (luonnollinen logaritmi).
• Voimat ja juuret: Käyttää x², √, x³, ³√.
• Murtoluvut: Käytä d/c murtolukujen syöttö- ja muunnosnäppäin

3.3 Mode Settings (DEG/RAD/GRAD)

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

1. Paina DRG avain.
2. Paina toistuvasti DRG to cycle through DEG (Degrees), RAD (Radians), and GRAD (Gradians). The current mode is indicated on the display.

3.4 Muistifunktiot

The calculator includes memory functions for storing and recalling values.

• STO (Store): Paina STO followed by a variable key (e.g., A, B) to store the displayed value.
• RCL (Recall): Paina RCL followed by the variable key to recall the stored value.
• M+ (Memory Plus): Lisää näytetyn arvon itsenäiseen muistiin.
• M- (Muistimiinus): Vähentää näytetyn arvon itsenäisestä muistista.

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. Huolto

4.1 Puhdistus

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 Pariston vaihto

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. Varmista, että laskin on sammutettu.
2. Paikanna laskimen takaa löytyvä paristolokero.
3. Avaa lokeron kansi varovasti.
4. Poista vanha LR44-paristo ja aseta uusi paikalleen varmistaen oikean napaisuuden (+/-).
5. Sulje paristolokeron kansi kunnolla.

4.3 Varastointi

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. Vianmääritys

5.1 Näyttöongelmat

• Tyhjä tai himmeä näyttö: 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.
• Input Error: 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 Laskin ei vastaa

Jos laskin lakkaa reagoimasta, kokeile nollausta. 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.
