VAB 2
With the scratchpad empty, or with a leading ‘‘A” or ‘‘0” entered in the first position in the
scratchpad, depressing VAB 2 selects AUTO range as the CPG range source. With a
scratchpad entry of a range (1 to 999,999 meters), depressing VAB 2 changes the CPG
range source to manual and will update the CPG range source value to the entered value.
VAB 3
With a valid target symbol, TXX or WXX, and valid coordinates previously entered in the
scratchpad, depressing VAB 3 will designate the scratchpad entry as the new Active Target.
Invalid entry will result in the ERROR message being displayed in the scratchpad. Without
data present in the scratchpad, depressing VAB 3 presents the Active Target coordinates in
the scratchpad. With the Active Target coordinates in the scratchpad, a second depression of
VAB 3 results in presentation of the Associated Data for the Target coordinates. Coordinate
and Associated Data in the scratchpad are ‘‘Display Only”; and are not editable or
transferable.
VAB 4
Depressing VAB 4 results in alternate presentation of the Target Report display (TGT
RPT:ON or TGT RPT:OFF). With selection of TGT RPT:ON, the CPG’s Video display will be
as shown in figure 3-25.10. Upon power up, the system defaults to TGT RPT:OFF.
