Note 1: When the MAIN board is replaced, format it according to the “NOTE OF MAIN
BOARD REPLACING” (refer to page 3) of the servicing notes.
Note 2: IC101 and J101 on the MAIN board cannot exchange with single. When IC101 and
J101 on the MAIN board are damaged, exchange the entire mounted board.

Note 1: When the MAIN board is replaced, format it according to the “NOTE OF MAIN
BOARD REPLACING” (refer to page 3) of the servicing notes.
Note 2: IC201 and IC1301 on the MAIN board cannot exchange with single. When IC201 and
IC1301 on the MAIN board are damaged, exchange the entire mounted board.
