AE-24-900. The number 24 refers to the gauge of wire and the number 900 refers to the number of windings, so yes those two coils are very similar. But the answer to your question is that manuals are very often wrong. Amazing how many times you will see wrong wire colors, wrong pin numbers, wrong coil numbers etc.
To the other fellows question, you should have 5 steel balls and 1 ceramic. And default settings is for 3 balls per game. If somebody changed it to 4 they probably messed with many other settings as well. I would go into utilities menu and do a factory install to get all your settings back to default.
