Unfortunately, I could not find any suitable information on this, neither in the instructions nor in the product pictures, which would lead to the assumption that this is possible. Therefore, I would guess that it is not. Perhaps ask the manufacturer directly (question about the item?):

I also have no information about compatibility with Swisscom TV. There is very little information about this product on the net, except for the information on the manufacturer's website. You would have to test it to be able to say for sure.
