TM 1-1510-225-10 3A-64 1   INTERCEPT  BEYOND  FIX.     The intercept message INTERCEPT BEYOND FIX indicates that the commanded  heading  will  not  cause the aircraft to intercept the programmed course on the TO side of the fix. 2   NO  COURSE  INTERCEPT.     The intercept message NO COURSE INTERCEPT indicates  that  the  commanded  heading  will  cause  the aircraft    to    diverge    from    the    programmed    course (crosstrack deviation will increase). 3   NO Message. No message indicates   either   that   there   is   no   TO   waypoint,   an intercept  is  not  programmed,  or  that  the  commanded heading will not intercept the programmed course prior to the fix. (f)    OK?    ENTER.        The   OK?   ENTER prompt at the bottom of the screen indicates that the procedure  for  accepting  the  entered  TO  waypoint  or DTK is to press the ENTER key. l.    Tuning Section (Tune Key). (1)   Tune  1/4  Page,  Comm.    Refer  to  Figure 3A-44. Figure 3A-44.  Tune 1/4 Page (COMM) (a)   COMM 1 or COMM 2.      The information  displayed  on  the  lines  below  this  heading applies to COMM 1 or COMM 2. (b)   ACTIVE.        This    field    displays    the frequency    currently    tuned    and    displayed    on    the respective   control   head.      This   display   will   appear briefly   but   will   turn   to   dashes   because  the  system interface  does  not  provide  a  return  frequency  input.   MAN   in   this   field   indicates   that   the   frequency   was manually entered via the control unit. (c)   PRESET.     The  pilot  can  enter  and store    a    frequency    in    this    field    using    the    flight management system keyboard. (d)   TRANSFER?.   This display indicates that the displayed preset frequency can be transferred to  ACTIVE  when  the    ENTER  key  is  pressed.    The control unit will reflect this change. (2)   Tune    2/4    Page,    Comm.        This    page displays  the  same  information  as  the  first  page  for additional COMM radios. (3)   Tune   3/4   Page,   Nav.    Refer  to  Figure 3A-45. Figure 3A-45.  Tune 3/4 Page, Nav (a)   NAV    1    or    NAV    2    –    The   station identifier   to   which   the   respective   NAV   receiver   is tuned.    KEY  will  be  displayed  when  the  frequency  or identifier  of  the  station  has  been  entered  using  the keyboard. (b)   FREQ.          This     line     displays     the frequency    currently    tuned    and    displayed    on    the respective control unit.  MAN in this field indicates that the  frequency  was  manually  entered  via  the  control head.  This field may also show KEY if the identifier is unknown. (c)   RANGE.        This    field    displays    the range  in  nautical  miles  and  tenths  of  a  nautical  mile from the aircraft's present position to the DME station.   The station identifier can also appear in this field if the control unit is placed in the DME HOLD mode.  NO ID will be displayed if the identifier of the held station is unknown. (d)   BRG.   This field displays the bearing in whole degrees.
