Sett på plass batteridekselet og fest det med skruen.

3.3 Første gangs strøm på

Trykk på PÅ/C button to turn on the calculator. The display will show the last calculation or be cleared, depending on the previous state.

4. Bruksanvisning

4.1 Grunnleggende beregninger

Slik utfører du grunnleggende aritmetiske operasjoner:

Skriv inn det første tallet.
Trykk på ønsket operasjonstast (+, -, ×, ÷).
Skriv inn det andre tallet.
Pressen = for å vise resultatet.

4.2 SkrivView Utstilling

The WriteView display lar deg legge inn og view mathematical expressions as they appear in textbooks. Fractions, roots, and other complex expressions are displayed in a natural format. Use the navigation keys (up, down, left, right arrows) to move the cursor within an expression for editing.

4.3 Function Modes

The calculator offers various modes for different types of calculations. Press the MODUS key to cycle through available modes such as:

NORMAL: For general arithmetic and function calculations.
STAT: For statistical calculations.
EQN: For solving equations.

Refer to the on-screen indicators (e.g., DEG, RAD, GRAD) for the current angle unit. Press DRG► (accessed via 2. klasse) to change the angle unit.

4.4 Vitenskapelige funksjoner

The EL-W531 includes 335 functions. Many functions are accessed directly, while others require pressing the 2. klasse key first. Common functions include:

Trigonometric: sin, cos, tan, and their inverse functions (sin^-1, cos^-1, så^-1).
Logarithmic/Exponential: log, ln, 10^xe^x.
Power/Root: x², √, x^y, ^y√x.
Brøker: a b/c key for mixed numbers and improper fractions.
Hukommelse: STO (store), RCL (recall), M+ (memory plus).

Consult the key labels and the calculator's display for specific function usage.

5. Vedlikehold

5.1 Rengjøring

To clean the calculator, wipe it gently with a soft, dry cloth. Do not use abrasive cleaners, solvents, or wet cloths, as these can damage the casing eller interne komponenter.
