3. Setup

3.1 Power Source

The Victor 900 calculator operates using a dual-power system: solar power and battery backup. Under sufficient lighting, the calculator will draw power from its solar panel. In low-light conditions or when solar power is insufficient, the battery backup (AG10 type) will automatically engage to ensure continuous operation.
