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”.
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”.
