Opsætning

Strømkilde

The Staples ST290-CCVS calculator operates on a dual power system: solar and battery. This ensures reliable operation in various lighting conditions.

• Solenergi: The calculator is equipped with a solar panel located above the display. For optimal performance, ensure the solar panel is exposed to sufficient light. This is the primary power source in well-lit environments.
• Batteristrøm: An internal battery provides power when light is insufficient or absent. The calculator automatically switches to battery power as needed. No user intervention is required for power source selection.

Indledende brug

Upon first use, or after prolonged storage, simply expose the calculator to light or press the ON/C CE button to activate the display. The calculator is ready for immediate use.

Opretholdelse

Proper care and maintenance will extend the life of your calculator.

• Rensning: Use a soft, dry cloth to clean the calculator's surface. For stubborn dirt, slightly dampen the cloth with water or a mild, non-abrasive cleaner. Avoid using harsh chemicals, solvents, or abrasive materials, 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.
• Batteri: The calculator uses an internal battery that is designed for long-term use. If the display becomes dim or unresponsive in low light conditions, ensure the solar panel is exposed to bright light. If issues persist, the battery may need professional replacement, though this is rare for solar-assisted models.
