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 t b7 Lower bit : 4 = 0100 t b2 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�, �monaural�, �original�, �copyright exists�, and �write allowed�. Example When 07 is displayed: Higher bit : 0 = 1000 t All 0 Lower bit : 7 = 0111 t b0+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�.
