A serial number consists of 11 characters. You can change each character by pressing one of the first 11
keys on the numeric keypad ( ,  ,  , ... ,  , ).
For example, when you press the   key, the first character of the serial number changes as follows:
0   1   2   ...   8   9   A   B   ...   X   Y   Z.
When you press the   key, the second character changes likewise.
You can specify a digit ("0" to "9") or a capital letter ("A" to "Z") for the first four characters of a serial
number, and you can specify a digit in the other seven characters (not capital letters).
