Surveyor from the network asked if I might be able to dig up a Sokkia 2LS Cygnus KS-102 manual for his Sokkia Total Station.  It wasn't easy to find but i managed to find one to share for support.

Cygnus (Topcon) KS-102 Reflectorless Total Station 

The Cygnus (designed by Topcon) provides superior performance at an unbeatable price for survey and construction applications. It's built tough to survive in extreme conditions, yet easy to set up and put to work quickly. Cygnus features 200m reflectorless operation and up to 2,000m using a single prism. There's even a built-in laser pointer to aid in layout work. With a 24-key alphanumeric interface, 24,000 point capable memory, and up to three days of operation off of a single charge, Cygnus is the perfect solution for medium duty survey and construction layout.
