Note 1: When the MAIN board is replaced, format it according

 

Note 2: IC751 and IC752 on the MAIN board cannot exchange

to the “NOTE OF MAIN BOARD REPLACING” (refer

 

with single. When IC751 and IC752 on the MAIN board

to page 4) of the servicing notes.

 

are damaged, exchange the entire mounted board.
