4-3. SCHEMATIC DIAGRAM - MAIN Board (1/2) (SA-WS20R) -
Note:
When the IC501, IC502, IC503 on the MAIN board,
or the complete MAIN board is replaced with a new
part, spread the compound for heat radiation to the
touching portion between the IC501, IC502, IC503
on the MAIN board and the heatsink.
• See page 34 for IC Block Diagrams. • See page 36 for IC Pin Function Description.
