What's worse is that I've noticed on two XRDs that were purchased from Siemens 
within the last year, there is a key lock right on the operator's console for 
defeating the interlocks!!!  Are other manufacturers doing this, or is it just 
Siemens?

(Melissa to researcher who installed the two Siemens units, "You are going to 
remove those keys and put them in a location inaccessible and unknown to anyone 
but yourself... NOW."  :-) )
