Reading the Display:
Convert the hexadecimal display into binary display. If more than two causes, they will be added.
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”.
Example When 07 is displayed:
Higher bit: 0 = 0000 t All 0
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”,
“Original”, “Copyright”, and “Write prohibited”.
