To switch between battery power and solar power on the Comix C-2735 Desktop Calculator, you don't need to manually select the power source. The calculator is designed to automatically use solar power when there is sufficient light available. If the solar power is not enough or in low-light conditions, the calculator will automatically switch to battery power. This ensures a continuous power supply and maintains a clear display. The package includes one AA battery, which should be inserted into the battery compartment to provide backup power. The solar panel serves as auxiliary power and helps conserve battery life.
