Note 2:
IC751 and IC752 on the MAIN board cannot exchange with single. When IC751 and IC752 on
the MAIN board are damaged, exchange the entire mounted board.
(Page 22)
Note 1:
When the MAIN board is replaced, format it according to the “NOTE OF MAIN
BOARD REPLACING” (refer to page 4) of the servicing notes.
