IOP DATA RECORDING AND DISPLAY WHEN OPTICAL PICK-UP AND NON-VOLATILE MEMORY (IC171 OF
BD 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 (IC171 of BD board), record
the IOP value on the optical pick-up according to the following procedure.
Record Procedure:
1. While pressing the [AMS] knob and p button, connect the power plug to the outlet, and release the [AMS] knob
and p button.
2. Turn the [AMS] knob to display “[Service]”, and press the [YES] button.
3. Turn the [AMS] knob to display “Iop Write” (C28), and press the [YES] button.
4. The display becomes “Ref=@@@.@” (@ is an arbitrary number) and the numbers which can be changed will blink.
5. Input the IOP value written on the optical pick-up label.
To select the number : Turn the [AMS] knob.
To select the digit : Press the [AMS] knob.
6. When the [YES] button is pressed, the display becomes “Measu=@@@.@” (@ is an arbitrary number).
7. As the adjustment results are recorded for the 6 value. Leave it as it is and press the [YES] button.
8. “Complete!” will be displayed momentarily. The value will be recorded in the non-volatile memory and the display will become “Iop
Write”.
9. Press the [REPEAT] button to complete.
Display Procedure:
1. While pressing the [AMS] knob and p button, connect the power plug to the outlet, and release the [AMS] knob
and p button.
2. Turn the [AMS] knob to display “[Service]”, and press the [YES] button.
3. Turn the [AMS] knob to display “Iop Read” (C27).
4. “@@.@/##.#” is displayed and the recorded contents are displayed.
@@.@: indicates the IOP value on the optical pick-up label.
##.# : indicates the IOP value after adjustment
5. To end, press the [AMS] knod or [MENU/NO] button to display “Iop Read”. Then press the [REPEAT] button.
