Table 1-2. Hexadecimal number - Decimal number Conversi

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 ”.

Note: Some sets may display “MD ERR TOC” depending on the

contents of CD disc to be recorded.
In this case, retry aging using another CD disc.
