Using the Minolta MN30WP camera is a breeze. To take a photo, simply turn on the camera, select the appropriate intelligent scene mode based on your shooting environment, and press the shutter button. For video recording, switch to the video mode and start recording. When shooting underwater, make sure the camera is properly sealed and within the 16 - foot waterproof limit. Don't forget to take it out of the water and dry it gently after use. As for maintenance, keep the camera clean by using a soft cloth to wipe the lens and the body. Avoid exposing the camera to extreme temperatures or humidity. If the battery runs out, recharge it using the provided charger. When you need more storage, insert a compatible MicroSD or MicroSDXC card into the memory card slot.
