Note on Printed Wiring Boards

X : parts extracted from the component side.

: Pattern from the side which enables seeing. (The other layers' patterns are not indicated.)

Caution:

 

Pattern face side:

Parts on the pattern face side seen from the

(Side B)

pattern face are indicated.

Parts face side:

Parts on the parts face side seen from the

(Side A)

parts face are indicated.

 

 

Main boards is four-layer pritnted board.

However, the patterns of layer 2 and 3 have not been included in this diagrams.

*Replacement of IC601 used in this set requires a special tool.
