I'm reaching out regarding the dual-frequency CATV device I'm interested in. Specifically, I would like to obtain a detailed manual for its configuration and setup. It's crucial for me to understand the operational aspects thoroughly to ensure smooth deployment. Additionally, if there are any tutorials available—be it video or written formats—that demonstrate the setup process or best practices, I would appreciate access to those as well. This support would be invaluable in helping me optimize the use of the product in my current project. Thank you!
