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).
