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 label of the optical pick-up. When replacing the optical pick-up or non-volatile memory (IC195 of BD board),
record the IOP value on the optical pick-up according to the following procedure.

RETRY CAUSE DISPLAY MODE IN MD
• In this test mode, the causes for retry of the unit during recording and stop can be displayed on the liquid crystal display. During
playback, the “track mode” for obtaining track information will be set.
This is useful for locating the faulty part of the unit.

Example
When 42 is displayed:
Higher bit : 4 = 0100 t b6
Lower bit : 2 = 0010 t b1
In this case, the retry cause is combined of “CLV unlock” and “ader5”.

Example When 84 is displayed:
Higher bit : 8 = 1000 t b7
Lower bit : 4 = 0100 t b2
In this case, as b2 and b7 are 1 and others are 0, it can be determined that the retry cause is combined of “Emphasis OFF”, “Monaural”,
“Original”, “Copyright”, and “Write allowed”.
Lower bit : 4 = 0100 t b2
In this case, as b2 and b7 are 1 and others are 0, it can be determined that the retry cause is combined of “Emphasis OFF”, “Monaural”,
“Original”, “Copyright”, and “Write allowed”.
Example When 07 is displayed:

In this case, as b0, b1, and b2 are 1 and others are 0, it can be determined that the retry cause is combined of “Emphasis ON”, “Stereo”,
“Original”, “Copyright”, and “Write prohibited”.
Lower bit : 7 = 0111 t b0 + b1 + b2
In this case, as b0, b1, and b2 are 1 and others are 0, it can be determined that the retry cause is combined of “Emphasis ON”, “Stereo”,
