Hi, I don’t sell these Black boxes. I just did a review on one. Have you asked the seller for a manual. He sells them on Amazon. They can help you contact the seller through email. Or if you find the product on Amazon, click on the seller, highlighted in blue. When it opens, look for detailed seller information. Click on that, and on the upper right should be a link for their customer service to that seller. You can email directly from there. Good luck.
