Note: “A1” board schematic diagram is divided into 4
blocks. “BH1” board schematic diagram is divided
into 2 blocks. “D” board schematic diagram is
divided into 2 blocks. Each block is named by its
function and block “number”. eg: Main Signal

(A1 Board-Block 001)
Joint connection between boards can be identified
using the block number followed by the grid's guide.
