Maintenance
1. Cleaning the Camera
- Camera Body: Use a soft, dry cloth to wipe the camera body. For stubborn dirt, slightly dampen the cloth with water. Avoid using organic solvents.
- Lens Mount: Keep the lens mount free of dust and debris. Use a blower brush to remove loose particles. Avoid touching the mirror or sensor directly.
- LCD Screen: Gently wipe the LCD screen with a microfiber cloth designed for optics.
2. Battery Care
- Charge the BP-511 battery fully before use.
- Store batteries in a cool, dry place when not in use.
- Do not expose batteries to extreme temperatures or direct sunlight.
3. Storage
When storing the camera for extended periods, remove the battery and memory card. Store the camera in a dry, dust-free environment, ideally with a desiccant to prevent mold and mildew.
Troubleshooting
- Camera Not Powering On: Check if the battery is correctly inserted and charged. Ensure the power switch is in the 'ON' position.
- No Image on LCD: Ensure the camera is in playback mode. If shooting, check viewfinder for image.
- Memory Card Error: Reinsert the CompactFlash card. If the error persists, try a different card. Ensure the card is not write-protected.
- Poor Image Quality: Check lens cleanliness. Ensure appropriate shooting mode and settings (ISO, aperture, shutter speed) are selected for the lighting conditions.
- Lens Not Focusing: Ensure the lens is securely attached and the autofocus switch on the lens (if present) is set to 'AF'. Check lighting conditions; very low light can hinder autofocus.
