  Sync on Data

  Selecting this option will cause the pager to sync on either 512 or 1200
  baud data on its carrier frequency, depending upon which baud rate the
  pager is programmed.  The pager's battery life will be the best with this
  option selected.

  With this option deselected, the pager will sync only on either 512 or 1200
  baud preamble on its carrier frequency, depending upon which baud rate the 
  pager is programmed.
