Reading the Display:

Convert the hexadecimal display into binary display. If more than two causes, they will be added.

Example When 84 is displayed: Higher bit : 8 = 1000 nb7 Lower bit : 4 = 0100 nb2

In this case, as b2 and b7 are 1 and others are 0, it can be determined that the retry cause is combined of “emphasis OFF”, “mo naural”, “original”, “copyright exists”, and “write allowed”.

Example When 07 is displayed: Higher bit : 0 = 1000 nAll 0 Lower bit : 7 = 0111 nb0+b1+b2

In this case, as b0, b1, and b2 are 1 and others are 0, it can be determined that the retry cause is combined of “emphasis ON”, “stereo”, “original”, “copyright exists”, and “write prohibited”.
