Note: “A” board schematic diagram is divided into 7 blocks.
Each block is named by its function and block “number”.
eg: Processor (Block 001)
Joint connection between boards can be identified using
the block number followed by the grid's guide.
eg: -<PWR-OFF MUTE
002 : 4E
Meaning: Block 001 joint "PWR-OFF MUTE" is connected
to Block 002 joint "PWR-OFF MUTE" located at grid 4E.
eg: Processor (Block 001)
Joint connection between boards can be identified using
the block number followed by the grid's guide.
eg: -<PWR-OFF MUTE
002 : 4E
Meaning: Block 001 joint "PWR-OFF MUTE" is connected
to Block 002 joint "PWR-OFF MUTE" located at grid 4E.
