– 6 –
Example 1: If “42” is displayed
Higher bit: 4=0100
→
b6
Lower bit: 2=0010
→
b1
This case shows that retry was made due to combined causes of
“CLV unlock” and “ADIP error ”.
Example 2: If “A2” is displayed
Higher bit: A=1010
→
b7 + b5
Lower bit: 2=0010
→
b1
This case shows that retry was made due to combined causes of
“cannot access”, “IV-R”, and “ADIP error ”.
