Shutdown raith SNF 2006-09-08 16:37:43: sample can't be unloaded

Greetings Raith Users:

This user was running the service.nav and not the exchange.nav procedure!!!

Users are strictly notified that they are NOT to perform emergency 
recovery or other service.nav procedures on their own without having 
either Raith Field Service or James Conway on the phone.

This is very dangerous as that all service and safety interlocks are in 
manual mode. Questions that the system software ask must be verified 
before next steps.
It is very easy to damage the interferometer mirrors, the robot transfer 
arm, or other hardware if you make a mistake in command sequence within 
this operation module.  Just don't do it.

Thank you,

James Conway
