Reading the Display:
Convert the hexadecimal display of each digit into binary display. The several causes are added and displayed.
Example When 84 is displayed:
Higher bit: 8 = 1000 → b7
Lower bit: 4 = 0100 → b2
This example shows that “Emphasis: OFF”, “Monaural”, “Original”, “Copyright exists” and “Writing is allowed” because b2 and b7 are 1
while all other bits are 0.
Example When 07 is displayed:
Higher bit: 0 = 0000 → all 0
Lower bit: 7 = 0111 → b0+b1+b2
This example shows that “Emphasis: ON”, “Stereo”, “Original”, “Copyright exists” and “Writing is prohibited” because b0, b1 and b2 are
1 while all other bits are 0.
