Using the Minolta MN30WP camera is a piece of cake. First, insert the provided 32GB MicroSD card into the slot. Then turn on the camera using the power button. To take a still photo, simply point the camera at your subject and press the shutter button. If you want to record video, switch to the video mode and press the record button. For different shooting situations, use the intelligent scene modes to let the camera adjust settings automatically. When using the 4X digital zoom, just use the zoom button to get the desired shot. As for underwater use, make sure the camera is properly sealed before submerging it up to 16 feet. After each use, especially after underwater use, wipe the camera clean with a soft, dry cloth. Keep it in a dry and cool place to avoid damage. Don't expose it to extreme temperatures or direct sunlight for a long time. And when the battery is low, charge it using the appropriate charger.
