1-6. PRECAUTION ON REPLACING THE VC-423 BOARD
Exif Model Data Check
When you replace to the repairing board, the written data of repairing board also might be changed to original setting.
When the data has changed because of board replaceing etc, check the data setting (Exif Model Data) is right. If not, rewrite to the right value.
