Opsætning
Installation af batteri

Billede: En detaljeret view showing the open battery compartment of the calculator, revealing two AAA batteries.
The 82Ms-A Scientific Calculator is powered by a long-lasting battery. To install or replace batteries:
- Sørg for, at lommeregneren er tændt SLUKKET.
- Find batteridækslet på bagsiden af lommeregneren.
- Skub dækslet af i den retning, som pilen angiver (hvis det er monteret).
- Insert new batteries, ensuring correct polarity (+/-) as marked inside the compartment.
- Sæt batteridækslet på plads, indtil det klikker sikkert på plads.

Tænd/sluk
- For at tænde: Tryk på ON nøgle.
- For at slukke: Tryk på FLYTTE så AC (AF).
Grundlæggende beregninger
Enter numbers using the numeric keypad. Use the +, -, ×, og ÷ keys for standard arithmetic operations. Press = for at vise resultatet.
Multi-Function Keys and 2-Line Display
The calculator features a 2-line display, showing both the input expression and the result simultaneously. Many keys have multiple functions, indicated by colored labels above or below them. These functions are accessed using the FLYTTE og ALPHA nøgler.
- FLYTTE: Activates the yellow-labeled functions. Press FLYTTE, then the desired key.
- ALPHA: Activates the red-labeled functions (variables, constants). Press ALPHA, then the desired key.
- MODE: Changes the calculator's mode (e.g., COMP, STAT, EQN). Press MODE repeatedly to cycle through options.
- CLR: Clears specific data or settings. Press FLYTTE så CLR to access clear options.
- DEL: Deletes the character at the cursor position.
- AC: Clears all input and returns to the initial state.
Avancerede funktioner
The 82Ms-A supports 240 functions, including trigonometric (sin, cos, tan), logarithmic (log, ln), power (x², x³), roots (√, ³√), fractions (a b/c), and statistical calculations. Refer to the specific key labels and their SHIFT/ALPHA functions for detailed usage.
- Trigonometriske funktioner: Brug synd, cos, tan keys. For inverse functions (sin⁻¹, cos⁻¹, tan⁻¹), use FLYTTE with these keys.
- Logarithmic Functions: Brug log (base 10) and ln (natural logarithm) keys.
- Power and Root Functions: Brug x² for squaring, FLYTTE så x² for square root (√). For other powers and roots, use x³ or FLYTTE så x³ (³√).
- Brøker: Brug ab/c key to input and convert fractions.
Opretholdelse
Rensning
To clean the calculator, use a soft, dry cloth. For stubborn dirt, slightly dampen the cloth with water or a mild, non-abrasive cleaner. Do not use strong solvents, alcohol, or abrasive cleaners, as these can damage the casing og display.
Opbevaring
Store the calculator in a cool, dry place away from direct sunlight and extreme temperatures. If storing for an extended period, it is recommended to remove the batteries to prevent leakage.
Fejlfinding
| Problem | Mulig årsag | Løsning |
|---|---|---|
| Lommeregneren tænder ikke. | Døde eller forkert installerede batterier. | Udskift batterierne med nye, og sørg for korrekt polaritet. |
| Skærmen er svag eller tom. | Lav batteristrøm. | Udskift batterierne. |
| Forkerte beregningsresultater. | Incorrect mode setting or previous calculation error. | Trykke AC to clear. Check the current mode using the MODE key and adjust if necessary. |
| Tasterne reagerer ikke. | Støv eller snavs under tasterne; intern fejlfunktion. | Gently clean around the keys. If problem persists, contact support. |
