Take your remote control, find “main manual”. your remote control might be in Chinese, here is a English version, it’s easy to find which is which.
1. “Main Manual”, find the bottom 3rd option: System Setup 2. After it you find the first one is “installation” 3. “point dish” 4. next you will see this page: Please make sure that the transponder number is on 1,3, 5, 9, 13, 17. There are no signal on other transponders. The satellite is on “122”。 If the green bar excess 10, the DishHD box will be able to receive signal from 122 AsiaSat4 satellite, which is a very low signal requirement.
I always make signal quality as high as possible in my installations.
