On the module are 4 directional buttons, and a display screen in the middle.

If the buttons are not Yellow, you're looking at a different module.

Use the list according to the last digit of the serial number. Take the next 5 letters in the sequence in order, starting from the displayed letter and wrapping around. Do not use the rule of the displayed letter. If a number has multiple strings, stay within that string.
