- Lens: Use a lens brush or air blower to remove dust, then gently clean with a microfiber lens cloth and a specialized lens cleaning solution if necessary.
- Sensor: Sensor cleaning should be performed with extreme care. If dust spots appear on images, it is recommended to have the sensor professionally cleaned by an authorized service center.
- LCD Screen: Use a soft, lint-free cloth. Avoid harsh chemicals.
4.2 Storage
When not in use, store the camera in a cool, dry place away from direct sunlight, high humidity, and extreme temperatures. Use a desiccant pack if storing in humid environments. Remove the battery if the camera will not be used for an extended period.
4.3 Battery Care
Charge the battery fully before first use. For optimal battery life, avoid completely discharging the battery regularly. Store batteries in a cool, dry place. If storing for extended periods, charge them to approximately 50% capacity.
5. Troubleshooting
5.1 Camera Does Not Power On
- Ensure the battery is correctly inserted and fully charged.
- Check that the battery contacts are clean.
- Try a different charged battery if available.
5.2 Images Are Out of Focus
