TM 55-1510-222-10 NOTE · The computer will convert coordinates in overlap area; however,  data  display  values  will reference appropriate zone. · The W key may be used to initiate easting entries; however, the computer     will     always     interpret such entries as an E input.  E will be  displayed  in  normal  UTM  data display. · The    extra    precision    values    are always   added   to   normal   values. As an example, South 4,476.995 m will     display     44765     (S)     in     the normal   display   and   995   in   extra precision display.  In other words, there  is  no  rounding  between  the two displays. 12.   Repeat  steps  2  through  11  for  each  way- point to be loaded. NOTE A  load  cycle  may  be  terminated  prior to    insertion    of    all    four    values    by moving data selector or thumbwheel. (b) Insertion of geographic way-point coordinates: a.  Data selector - L/L WY PT. Data  displays  indicate  last  coordinates  inserted  into the selected way-point. b.  Thumbwheel Set to way-point number to be loaded. c.        To    load    latitude    Press    keys    in sequence,   starting   with   N   or   S   to   indicate   north   or south. Example:    42°  54.0'  North  =  N  4  2  5  4  0.    Observe that INSERT/ADVANCE pushbutton annunciator illuminates   when   first   key   is   pressed,   and   latitude appears in left data display as keys are pressed. d.  INSERT/ADVANCE pushbutton Press. Observe pushbutton annunciator extinguishes. e.  To load longitude Press keyboard keys in  sequence,  starting  with  W  or  E  indicating  west  or east. Example:    87°  54.9'  West  =  W  8  7  5  4  9.    Observe that INSERT/ADVANCE pushbutton annunciator illuminates   when   first   key   is   pressed,   and   longitude appears in display as keys are pressed. f.  INSERT/ADVANCE pushbutton Press. Observe pushbutton annunciator extinguishes. g.      If   desired   to   insert   extra   precision coordinate data Press INSERT/ ADVANCE pushbutton. Observe   that   arc-seconds   for   loaded   latitude   and longitude,  to  nearest  tenth  of  a  second,  appear  in  left and right data displays, respectively. h.  To load related arc-second values for latitude Press keys in sequence, starting with N. Example: 35.8 North =N 358. i.  INSERT/ADVANCE pushbutton Press. Observe pushbutton annunciator extinguishes. j.    To  load  related  arc-second  values  for longitude Press keys in sequence, starting with E. Example: 20.1 East = E 201. k.  INSERT/ADVANCE pushbutton Press. Observe pushbutton annunciator extinguishes. l.    Repeat  steps  2  through  11  for  each way-point to be loaded. NOTE · In    above    example,    if    INSERT/ ADVANCE pushbutton was pressed,     the     following     normal display  would  appear:    42°  54.    5 (N)  and  87°  54.    3(W).    The  extra precision    values    are    added    to normal   values   and   normal   data displays are not rounded off. · The normal geographic coordinates must always be loaded    prior    to    extra    precision values. · The directions N or S and E or W are     established     during     normal coordinate  entry.    Either  key  may be   used   to   initiate   entry   during extra  precision,  loads  and  values will be added to the extra precision   value   without   affecting direction. · It is characteristic of the computer display   routine   to   add   0.2   arc- seconds to 3-51
