FMI 60746 Upgrade from Signa HD_M5 to Signa HD_M5A Must Be Installed Prior to FMI 60752 Upgrade. 3T Excite HD 12.0.

Can FMI 60752 Upgrade Signa HD from 12.0_M5A to 12.0_M5B be Installed on Systems Running 12.0_M5 Software, or Must System be Upgraded to 12.0_M5A First? See Long Description The FE received FMI 60752 "Upgrade Signa HD from 12.0_M5A to 12.0_M5B" for one of the Signa Excite HD systems he services. But this system is running 12.0 M5 software, not 12.0 M5A. Now he is wondering whether he needs to first upgrade the system to 12.0 M5A via FMI 60746 "Upgrade from Signa HD_M5 to Signa HD_M5A" before installing FMI 60752. Reading the FMI instructions to find the answer doesn't help much as there are seemingly conflicting statements on this point. In the PURPOSE section of FMI 60752 it states as follows: "This software FMI upgrades Signa HD M5A sites to M5B product level...". But in the EFFECTIVITY section, this statement is made: "The FMI should be executed for all Signa HD M5 and Signa HD M5A systems. " Also in the ISERV this statement is made: Effectivity:This FMI applies to ALL 1.5T & 3T Signa 12.0 HD M5 and 12.0 M5A MR systems
