The Radio Information Board

Ok when you hold down the "Light" key and the "TA" key and up pops "TEST" then if you press "TEST" and the freqeunices appear. Ok here is the I think secret. If you press the "Light" key then while still holding the light key press "LO" the word "TUNE" Appears! There is all these numbers which appear when you press "TA" what does changing the Numbers do?

this is how you align the radio... not a secret, just a bad place to be without a comm. service monitor.
