Hi, can anyone help me please to set up Aghapy channel, thanks.

I called UBI yesterday, but the lady told me that they don't help for public channels. Anyway, she told me to enable Signal Setup 2, 3 and 4 and then select Tune and Scan. Next, she asked me to go to public and asked me to select channel 6 for Aghapy, but what was there is Trinity channel!

Please help me to setup this channel, and if possible with steps required. Thank you again.
