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 t b6

Lower bit : 2 = 0010 t b1

In this case, the retry cause is combined of “CLV unlock” and “ader5”.

When A2 is displayed:

Higher bit: A = 1010 t b7 + b5

Lower bit : 2 = 0010 t b1

The retry cause in this case is combined of “Access fault”, “IVR rec error”, and “ader5”.
