3. Using a small screwdriver, carefully remove the screw(s) securing the cover.
4. Remove the cover and replace the old LR44 battery with a new one, ensuring correct polarity (+/-).
5. Uždėkite baterijų skyriaus dangtelį ir pritvirtinkite jį varžtu (-ais).

2.2 Pradinis įjungimas

Norėdami įjungti skaičiuotuvą, paspauskite [ĮJUNGTA] button. The calculator will display '0' on the screen. If the display is blank, ensure there is sufficient light for the solar panel or check the battery installation.

3. Naudojimo instrukcijos

This section provides a guide to the various functions and operations of your Casio fx-300MS Plus 2nd Edition Scientific Calculator.

3.1 Pagrindiniai skaičiavimai

Įveskite skaičius naudodami skaitmeninę klaviatūrą ir atlikite veiksmus naudodami [+], [-], [×], ir [÷] mygtukai. Paspauskite [=] kad būtų rodomas rezultatas.

3.2 Mokslinės funkcijos

The calculator offers a wide array of scientific functions. Many functions are accessed by pressing the [SHIFT] key followed by the desired function key (indicated in yellow above the keys).

• Trigonometrinės funkcijos: Naudokite [nuodėmė], [nes], [įdegis] for sine, cosine, and tangent. Inverse functions (nuodėmė⁻¹, nes⁻¹, įdegis⁻¹) are accessed via [SHIFT].
• Logaritmai: Naudokite [žurnalas] dešimtainio logaritmo ir [ln] natūraliajam logaritmui.
• Galios ir šaknys: Naudokite [x²] for square, [√] for square root, [x³] for cube, and [³√] for cube root. General powers ([^]) and roots ([SHIFT] [^]) are also available.
• Factorials: Naudokite [x!] (pasiekiama per [SHIFT]) for factorial calculations.

3.3 Fraction Calculations

The dedicated fraction key [ab/c] allows for easy entry and calculation of fractions and mixed numbers. Use [SHIFT] [a b/c] to convert between improper fractions, mixed numbers, and decimal equivalents.

3.4 Statistical Calculations

To enter Statistics Mode, press [REŽIMAS] and select the appropriate statistical option (e.g., SD for standard deviation, REG for regression). Follow the on-screen prompts to input data and perform calculations.

3.5 Variable Memory

The calculator can store up to 9 variables (A-F, X, Y, M). To store a value, enter the number, press [STO], and then press the alpha key corresponding to the desired variable (e.g., [ALPHA] [A]). Norėdami iškviesti reikšmę, paspauskite [RCL] and the variable key.

3.6 Režimai ir nustatymai

Paspauskite [REŽIMAS] button to cycle through different calculation modes (e.g., COMP for basic arithmetic, STAT for statistics). The [NUSTATYMAS] button (accessed via [SHIFT] [MODE]) allows you to configure display settings, angle units (degrees, radians, grads), and number formats.

3.7 Išjungimas

Norėdami išjungti skaičiuotuvą, paspauskite [SHIFT] sekė [Kintamoji srovė] (IŠJUNGTA).

4.3 Akumuliatoriaus keitimas

If the display becomes dim or calculations are slow, even in good lighting, it may be time to replace the LR44 backup battery. Refer to section 2.1 for battery installation instructions.

5. Problemų sprendimas

• Ekranas tuščias: Ensure the calculator is in sufficient light for the solar panel. If it remains blank, replace the LR44 backup battery.
• Neteisingi rezultatai: Check the current mode (e.g., degrees vs. radians for trigonometric functions). Press [SHIFT] [MODE] to access setup and adjust settings. Ensure correct input of numbers and operations.
• Skaičiuoklė užstringa: Paspauskite [Kintamoji srovė] button to clear the current calculation. If the issue persists, try removing and reinserting the battery to perform a hard reset.
• Mygtukai nereaguoja: Ensure no debris is lodged under the keys. Clean the calculator as described in section 4.1.
