Thanks for your reply. No, Telstar4 isn't there either.
I found lots of similar threads, must be a popular question, just one of them:
http://www.sadoun.net/forums/fortec-star/1833-how-do-you-add-new-satellite.html
And on another forum, reviewer of this CS5k also mentions, some sats are missing, but there are blank entries at the end of list. I will read manual again.
Question becomes: "How to rename satellites in STB menu?"
