We had a call from our current guests. They were asking if they could do something to get the TV in the holiday home working properly. A couple of the TV channels were not displaying correctly. We use the Freesat service. My guess was the transmitting companies had changed some frequencies and this had not been updated on the TV. As usual we'd checked the TV worked before the rental started. We do this for every rental, but I confess we don't check every channel routinely.
I'd noticed the guest were not comfortable with technology, so I had to visit the holiday home to re-tune the TV. It is not difficult to do, but the round trip took over an hour. I'd not previously worked with this particular TV tuning, but it was reasonably straightforward. My hunch was proved correct and now the guests have excellent quality reception.
