How to unlock channels on a Golden Interstar DVB-T/S 8700 CRCI Premium sat receiver? - golden interstar receiver

Satellite receiver I mentioned above, and most routes are blocked. Can you please tell me how to release it.

I have absolutely no idea what to do.
All the commands that you need to press the receiver.
The code that I downloaded from the Internet and where.

Thanks
