Opsætning

Strømkilde

Your CASIO MS-20YC calculator operates on solar power with a backup battery. Ensure sufficient light for optimal performance. The backup battery is pre-installed to provide power in low-light conditions.

• Solenergi: The calculator primarily uses solar energy when sufficient light is available.
• Backup batteri: A nonstandard battery is included and installed to ensure continuous operation when solar power is insufficient.
• Automatisk slukning: The calculator features an automatic shut-off function to conserve battery life when not in use.

Indledende brug

Upon first use, ensure the calculator is exposed to light. If the display is blank or dim, press the AC (All Clear) button. The calculator is ready for use once the display shows '0'.

Opretholdelse

Rensning

To clean your calculator, gently wipe the surface with a soft, dry cloth. Do not use abrasive cleaners, solvents, or chemical sprays, as these can damage the display or casing.

Opbevaring

Opbevar lommeregneren et køligt og tørt sted væk fra direkte sollys og ekstreme temperaturer. Undgå at placere tunge genstande oven på lommeregneren for at forhindre beskadigelse af displayet eller tasterne.

Udskiftning af batteri

If the display becomes consistently dim even in sufficient light, the backup battery may need replacement. Battery replacement should ideally be performed by an authorized service center to ensure proper handling and to avoid voiding any warranty.

Fejlfinding

• Skærmen er tom eller svag:
  Ensure the calculator is exposed to adequate light. If the issue persists, the backup battery may be low or depleted.
• Forkerte beregninger:
  Trykke AC to clear all previous calculations and memory. Re-enter your calculation carefully.
• Taster reagerer ikke:
  Check for any debris lodged under the keys. Gently clean around the keys. If the problem continues, contact customer support.
• Calculator turns off unexpectedly:
  This is likely the automatic shut-off feature. If it occurs too frequently during active use, ensure sufficient light for solar power or consider battery replacement.
