Opsætning
1. Batteriinstallation
The Deli 1700 240F Scientific Calculator operates on both solar power and two nonstandard batteries. For optimal performance, ensure batteries are installed correctly.
- Find batteridækslet på bagsiden af lommeregneren.
- Using a small screwdriver, carefully remove the screw and slide off the battery compartment cover.
- Insert two nonstandard batteries, ensuring the positive (+) and negative (-) terminals are aligned correctly as indicated inside the compartment.
- Sæt batterirummets dæksel på igen og fastgør det med skruen.
Note: The calculator also utilizes solar power. Ensure adequate light exposure for solar operation, especially when batteries are low or not installed.
2. Første opstart
Tryk på [PÅ] button to turn on the calculator. The display should show '0' or a similar initial state. If the display does not appear, check battery installation or ensure sufficient light for solar power.

- Trigonometriske funktioner: [SIN], [COS], [TAN] og deres inverse funktioner ([FLYTTE] + [SIN⁻¹]osv.).
- Logaritmiske funktioner: [LOG] (grundtal 10) og [LN] (naturlig logaritme).
- Potens- og rodfunktioner: [x²], [√], [xʸ], [ʸ√x].
- Factorial: [x!].
3. Hukommelsesfunktioner
Store and recall values using the memory keys:
- [M+]: Tilføjer den viste værdi til hukommelsen.
- [M-]: Trækker den viste værdi fra hukommelsen.
- [MR]: Henter værdien fra hukommelsen.
- [MC]: Rydder hukommelsen.
4. Vinkelenheder
The calculator supports Degree (DEG), Radian (RAD), and Grad (GRA) angle units. Press [MODE] repeatedly to cycle through the angle units. The current unit is indicated on the display.

Opretholdelse
1. Rensning
Brug en blød, tør klud til at rengøre lommeregneren. Brug ikke slibende rengøringsmidler, opløsningsmidler eller spray direkte på lommeregneren. Undgå for meget fugt.
2. Udskiftning af batteri
When the display becomes dim or calculations are incorrect, it may be time to replace the batteries. Follow the battery installation steps outlined in the Setup section. Always replace both batteries at the same time with new ones of the same type.
3. Opbevaring
Store the calculator in a cool, dry place away from direct sunlight and extreme temperatures. Avoid dropping the calculator or subjecting it to strong impacts.
Fejlfinding
| Problem | Mulig årsag | Løsning |
|---|---|---|
| Skærmen er tom eller svag. | Low batteries or insufficient light for solar power. | Replace batteries or move to a brighter area. |
| Forkerte beregningsresultater. | Incorrect mode setting (e.g., angle unit) or input error. | Check angle unit (DEG/RAD/GRA). Clear all memory and re-enter calculation. Press [CLR] to clear current calculation. |
| Lommeregneren reagerer ikke på tastetryk. | Temporary system error or very low power. | Trykke [PÅ]/[OFF] to restart. If issue persists, remove and reinsert batteries. |
