How does the SPLAKS 131001 Elegant Basic Calculator switch between solar and battery power?

[DeMackenzie]

The SPLAKS 131001 Elegant Basic Calculator is designed to automatically manage its power source. It seamlessly transitions between solar and battery power depending on the available light. Under bright lighting conditions, the calculator prioritizes solar power for operation. When the ambient light diminishes, the calculator intelligently switches to the LR44 battery included with the device. This automatic switching eliminates the need for any manual adjustments. Should you experience any issues with the calculator's functionality or display, ensure it's in a well-lit environment or verify the battery's condition. If a battery replacement is necessary, consult the SPLAKS 131001 Elegant Basic Calculator's manual for detailed instructions.
