3-1 Description of Structure

(1) Configuration and locations of circuit boards
The configuration of circuit boards in DZ-MV580A/MV550A and their locations are very similar to
those in the base models DZ-MV380A/MV350A, except for whether the FAF circuit board is
provided or not.
The DZ-MV380A/MV350A had the FAF circuit board between the FRT and AEL circuit boards:
The DZ-MV580A/MV550A does not have this, since the FRT-H/FRT circuit board is directly
connected to AEL-H/AEL circuit board.
