Maintenance
- Cleaning: Use a soft, dry cloth to clean the calculator's surface. For stubborn dirt, slightly dampen the cloth with water. Avoid using harsh chemicals, abrasive cleaners, or solvents, as these can damage the display or casing.
- Storage: When not in use, store the calculator in its protective wallet case to prevent scratches and damage. Avoid exposing it to extreme temperatures, high humidity, or direct sunlight for extended periods when stored.
- Solar Panel: Keep the solar panel clean and unobstructed to ensure continuous power supply.
Troubleshooting

Ensure the solar panel is exposed to sufficient light. The calculator requires ambient light to operate. If in a dimly lit environment, move it to a brighter area.

Press ON/C to clear all previous operations and memory. Re-enter your calculation carefully. Check for correct key presses and operation order.
