fixed and secured position in a truck and operated at a new location, would be different though arguably one might want to perform more daily QC testing.<o:p></o:p></p>

after transport and prior to patient use. I wasn't able to find that requirement in the user's manual, and the FSE didn't give me the reference either.<o:p></o:p></span></p>
