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 ”.
How to Use Table 1-1.:
Use table 1-1. by converting hexadecimal number of each digit
into decimal number (see table 1-2). If an error occurred by two
or more causes, respective numbers are added.
