First, confirm items that you would like to set. The X is like a flag, which can be 0-f(hex), each bit stands for one item, bit3:the value of 0x2A 0x2B, bit2:manufacture string, bit1:serial number, bit0:product string.

Case1 The values in the address 0x2A,0x2B(setting of initial volumes) are valid, but all the string names are disabled.

X setting is listed below:

Since X=1000(hex)=8, the Magic code 0x670X = 0x6708.

Case2 The values in the address 0x2A,0x2B are valid, and product string is enabled.

Since X=1001(hex)=9, the Magic code 0x670X = 0x6709.

Case3 The values in address 0x2A,0x2B are valid, and all of the string names are enabled.

X setting is listed below:

Since X=1111(hex)=f, the Magic code 0x670X = 0x670f.
