HT1250 model number help.

I was on this forum and on Batlabs looking at model number decoding. I'm trying to see how many channels the radio is and what frequency range it is. Here is the numbers AAH258DF9AA5AN, the 5 after the second AA should be the number of channels in the radio, I thing??? But it's not on any on the lists. Thanks John
