Note on Printed Wiring Board:

•Y: parts extracted from the conductor side.

•f : internal component.

• : 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
(Conductor Side)	the pattern face are indicated.
Parts face side:	Parts on the parts face side seen from
(Component Side)	the parts face are indicated.

•MAIN board is four-layer printed board.

However, the patterns of layers 2 and 3 have not been in- cluded in this diagrams.

*Replacement of IC601 and IC801 used in this set requires a special tool. Therefore, it cannnot be replaced.
