Using your Minolta MN30WP camera is easy. First, insert the provided 32GB MicroSD card into the MicroSD/MicroSDXC memory card slot. Turn on the camera, and you'll see the 2.8” TFT LCD screen light up. For taking photos, select the appropriate intelligent scene mode based on your shooting environment, like landscape or portrait. If you want to get closer to your subject, use the 4X digital zoom. To record 1080p Full HD videos, just press the video button. When you're done shooting, you can easily review your photos and videos on the screen. As for underwater use, make sure the camera is properly sealed before taking it into the water up to 16 feet deep. After using it underwater, dry it with a soft cloth. Keep the camera away from extreme temperatures and direct sunlight. Also, charge the battery regularly to ensure it's always ready for your next adventure.
