IOP DATA RECORDING AND DISPLAY WHEN OPTICAL PICK-UP AND NON-VOLATILE MEMORY (IC195 OF
BD (MD) BOARD) ARE REPLACED
The IOP value labeled on the optical pick-up can be recorded in the non-volatile memory. By recording the value, it will eliminate the need
to look at the value on the optical pick-up label. When replacing the optical pick-up or non-volatile memory (IC195 of BD (MD) board),
record the IOP value on the optical pick-up according to the following procedure.
Record Procedure:
1. Press the x (CD), x (MD) and [YES] buttons at the same time.
