  EMERGENCY PRIORITY


  This feature has two choices:  POLITE and IMPOLITE.  A polite transmission
  will sense the channel for activity and transmit when the channel is clear,
  and an impolite transmission will 'blast' the channel without checking for
  activity.  This feature enables the user to choose which transmission
  occurs first.  A standard system will transmit 15 impolite transmissions
  followed by 5 polite transmissions.  This feature, along with the NUMBER OF
  POLITES and NUMBER OF IMPOLITES, allows the user much flexibility in
  configuring the emergency sequence.  Whichever selection is made, polite or
  impolite priority, that selection can not have a zero for number of
  transmissions.  The one that is not priority, however, may be set to zero.
