  42. The Checksum Adjustment and Checksum are calculated automatically after
  43. the data has been edited for the NAM.  The sum of all words in the NAM plus
  44. the last two must equal a number with "0" in the last two digits.  The radio
  45. checks this sum and if it isn't correct, the radio assumes the NAM is bad or
  46. that it has been tampered with.

  49.  * - These bits are used only by AT&T,Hitachi and Mitsubishi. They are A/B
  50.  Enable and Roam Inhibit. They must be "0" for all other models.
  51.  
  52. ** - My information does not agree here. One source claims that address 03
  53.      has 6 bits and that address 0D has 7 bits. The other source states the
  54.      the exact opposite.
