*1 : Users' unique data is saved in IC611 and IC51 of the DCP-28 board. When these ICs are replaced on the occasion of board
replacement or IC replacement, the users' unique data will be lost and the data is returned to the default data when the unit is
shipped from the factory. For the menu setting, refer to Section 4 and re-set the data. For the adjustment items that are required in
accordance with the replacement, refer to Section 1-17-6.
*2 : The initial data for this model cannot be written into the new EEPROM (IC202) outside the factory.
When the IFA-11 board is replaced, remove IC202 from the former board and reinstall it to the new replacement IFA-11 board.
When IC202 needs to be replaced due to defective IC, contact your local Sony Sales Office/Service Center.
*3 : Data cannot be saved in IC801 on the FP-121 board.
When IC needs to be replaced due to defective IC, contact your local Sony Sales Office/Service Center.
*4 : The initial data for this model cannot be written into the new EEPROM (IC31) outside the factory.
When the DR-433/477 board is replaced, remove IC31 from the former board and reinstall it to the new replacement DR-433/477
board.When IC31 needs to be replaced due to defective IC, contact your local Sony Sales Office/Service Center.
