TM 55-1510-219-10 2.    To   load   zone   and   easting   values Press   keys   in   sequence,   starting with"E". (Example:   Zone   16,   425   km   East   =   E16   425. Observe  that  zone  and  easting  in  kilometers  appear  in right data display as keys are pressed.) 3.    INSERT/ADVANCE pushbutton Press. (Observe pushbutton light remains illuminated.) 4.    To  load  northing  data  Press keys in sequence, starting with "N" or "S" to indicate north or south hemisphere. (Example:   4749   km   North   =   N   4749)   Observe northing kilometers appear in left data displays as keys are pressed.) 5.    INSERT/ADVANCE pushbutton Press. (Observe pushbutton light remains illuminated.) 6.    INSERT/ADVANCE pushbutton Press. (Observe extra precision display for present position northing  and  easting,  to  the  nearest  meter,  appears  in left and right data displays, respectively.) 7.    To load extra precision easting data Press   keys   in   sequence,   starting with "E". (Example:   297   m      East   =   E   297)   Observe   that easting meters appear in right data display as keys are pressed.) 8.    INSERT/ADVANCE pushbutton Press. (Observe pushbutton light remains illuminated.) 9.    To      load    extra    precision  northing data Press keys in sequence, starting with "N" or "S". (Example:   901   m   North   =   N   901)   Observe   that northing meters appear in left data displays as keys are pressed.) NOTE The    value    is    always    added    to normal  value  regardless  of  which key (N/S) is pressed to initiate the entry. The normal entry establishes the hemisphere. 10.    INSERT/ADVANCE pushbutton Press. (Observe latitude and longitude data is displayed in UTM and INSERT/ ADVANCE pushbutton light extinguishes.) NOTE The computer will convert coordinates   in   the   overlap   area; however display values will reference appropriate zone. NOTE The   "W"   key   may   be   used   to initiate   easting   entries;   however computer    will    always    interpret such entries as an "E" input.  "E" will  be  displayed  in  normal  UTM display. NOTE Extra  precision  values  are  always added  to  normal  values.    As  an example,  South  4,  476,995  m  will display "4476S" in normal display and     "995"     in     extra     precision display.      There   is   no   rounding between the two displays. (b)    To  insert  geographic  coordinates  of aircraft present position: NOTE Prior to pressing INSERT/ADVANCE pushbutton, any incorrectly loaded data can be corrected     by     pressing     CLEAR pushbutton   and   loading   correct data. 1.    Data selector L/L POS. (Observe   that,   prior   to   initial   load,   the   INSERT/ ADVANCE pushbutton light is illuminated.) 2.    To  load  latitude  data  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  latitude  appears  in  left  data  display  as  keys  are pressed.) 3.    INSERT/ADVANCE pushbutton Press. (Observe pushbutton light remains illuminated.) 4.    To load longitude data Press keys in sequence,  starting  with  "W"  or  "E" to indicate west or east. 3-51
