Using the Minolta MN4K40NV camcorder is easy. First, insert the provided 32GB SD card into the SDXC memory card slot. Then, charge the Li - ion battery with the AC adaptor. Once it's ready, you can start recording videos or taking photos. For night - time shooting, switch to the infrared night - vision mode. When you want to capture a long - term event, use the time - lapse feature and set your desired interval. To add accessories like a lens filter or an external microphone, use the front 37mm lens threading or the hot - shoe mount. Just make sure to insert the 3.5mm plug of the microphone into the MIC port. When it comes to maintenance, keep the camcorder in a dry and clean place. Avoid exposing it to extreme temperatures. Clean the lens with a soft, dry cloth regularly. Also, don't forget to format the SD card periodically to ensure smooth operation.
