Remove a registered channel

[Dimnox]

Hello,

I would like to buy a Samsung UE40H6500 TV, but my fried who has an UE32H6400 model made me unsure.
As he pointed out, there is no way to delete a registered channel in the newest series H. WTF? It should be a base function.
In the user manual Samsung alleges it's available in the Broadcasting > Edit Channel menu item. But there is no Delete button anywhere.
Is this an individual problem or a bug?

Thanks a lot.
