Note: Rockwell Collins recommends that FM immunity service bulletins be incorporated in 618M-3( ) and VHF-700( ) units at the same
time as the 8.33 service bulletins. Installing FM Immunity service bulletins at the same time as 8.33 kHz service bulletin
will save duplicated test times. The VHF-700A, 618M-4/4A, and VHF-900 are FM immunity compliant.
