Operation confirmed. In simple tests, all button operations, recording, and playback worked without issue. After purchase, I didn't have the opportunity to use it for a long time, and it has been stored at home. The exterior shows signs of use and storage, such as scratches, minor blemishes, and faded lettering. Please check the photos for the condition. The accessories are all that are shown in the photos.
