Figure 80. Recall Screen
The first Recall screen (see Figure 80) simply lists all data that resides on the machine in chronological order
with newest data files at the top. This screen displays the files within the currently selected storage location
(see Section 4.4.2), either the USB Flash Drive or the “My Documents” folder. Remember that file names are
simply the encoded time/date when the file was saved. When searching for a particular data set or group of
data sets, the initial Recall screen will be used to scroll though lots of data files quickly. The operator will then
select a data file with a time/date in the neighborhood of file(s) of interest and then tap the Details button.
The Recall Details screen then allows the operator to move through data sets one at a time to zero in on
particular data sets of interest (see Figure 81).

Information about each data set is displayed here one data set at a time. The operator can see whether the
file has already been sent to Reachback; as well as view the operator-entered metadata associated with the
data set, and nuclide identifications made while collecting the data. Identifications made on Blank and Known
spectrum types in multiple-spectrum mode are excluded from this list of identifications.
