Not all functions are implemented on all LX200s.

'Slew scope' and 'slew Guide' should always work, even with truly
ancient LX200s. Some of the other functions will just about always work,
such as the arrow controls. The GPS-related functions, for example,
obviously aren't going to do anything on a scope that lacks GPS. Which
flavor of LX200 do you have (GPS, AutoStar, etc.)?
