Reading the Retry Cause Display
Reading the Display:
Convert the hexadecimal display into binary display. If more than two causes, they will be added.

Example
When 42 is displayed:
Higher bit : 4 = 0100 n b6
Lower bit : 2 = 0010 n b1
In this case, the retry cause is combined of “CLV unlock” and “ader5”.
Higher bit : 4 = 0100 n b6
Lower bit : 2 = 0010 n b1
In this case, the retry cause is combined of “CLV unlock” and “ader5”.
When A2 is displayed:
Higher bit : A = 1010 n b7+b5
Lower bit : 2 = 0010 n b2
The retry cause in this case is combined of “access fault”, “IVR rec error”, and “ader5”.
Higher bit : A = 1010 n b7+b5
Lower bit : 2 = 0010 n b2
The retry cause in this case is combined of “access fault”, “IVR rec error”, and “ader5”.

Example When 84 is displayed:
Higher bit : 8 = 1000 n b7
Lower bit : 4 = 0100 n 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 exists”, and “write allowed”.
Lower bit : 4 = 0100 n 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 exists”, and “write allowed”.
Example When 07 is displayed:
Higher bit : 0 = 1000 n All 0
Lower bit : 7 = 0111 n 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 exists”, and “write prohibited”.
Lower bit : 7 = 0111 n 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 exists”, and “write prohibited”.
