Power Source
Your CATIGA CD-2786 calculator is designed with dual power capabilities: solar and battery.
- Solar Power: The calculator will automatically utilize solar power when sufficient light is available. Ensure the solar panel (located above the display) is exposed to light for optimal performance.
- Battery Power: A battery is pre-installed to provide power in low-light conditions or when solar power is insufficient. The calculator will seamlessly switch between power sources as needed.
Initial Use
To turn on the calculator, press the ON/AC button. The display will show "0.".
