Opsætning
Strømkilde
The Casio DS-2B-GD-W-DP calculator operates using a dual power system: solar power and battery power. It automatically switches between these sources based on ambient light conditions.
- Solenergi: The calculator is powered by solar cells when sufficient light is available. Ensure the solar panel, located above the display, is exposed to light for operation.
- Batteristrøm: When light is insufficient, the calculator automatically switches to battery power. No user intervention is required for this transition.
