5. Maintenance
Proper maintenance ensures the longevity and performance of your Pentax Optio WG-2 GPS camera, especially given its rugged design.
- Cleaning the Camera Body: After use in sandy, muddy, or salty environments, rinse the camera with fresh water. Ensure all covers are securely closed before rinsing. Dry the camera thoroughly with a soft cloth.
- Cleaning the Lens and LCD Screen: Use a soft, lint-free cloth specifically designed for optics. For stubborn smudges, a small amount of lens cleaning solution can be applied to the cloth (not directly to the lens).
- Seal Inspection: Periodically inspect the rubber seals around the battery/memory card compartment and USB/HDMI port for any signs of wear, cracks, or debris. Damaged seals can compromise the camera's waterproof integrity.
- Storage: Store the camera in a cool, dry place away from direct sunlight and extreme temperatures. If storing for an extended period, remove the battery.

6. Troubleshooting
If you encounter issues with your camera, refer to the following common problems and solutions:
- Camera does not power on:
- Ensure the battery is fully charged and correctly inserted.
- Check if the battery contacts are clean.
- Battery drains quickly:
