making sure the appropriate pack gap is maintained between all the packages. The
bar graph in the screen monitors progress. Currently, the screen shows that four

500. The IXR icon flashes telling you the APEX is currently learning the IXR signal.

6)
After at least nine packages have been passed, the preliminary IXR-signal learn is
complete, as shown by the check mark below the IXR icon in the screen below.
Pass Products to Learn Detect Level
7)
Continue passing packages so the detector can now start learning the detect level.
The detect-level icon flashes telling you the APEX is currently learning the detect
levels. The values for the detect levels update every 10 seconds, and the entire
learning process takes approximately 60 seconds to complete. You may, however,
stop the detect-level calibration at any time by pressing the Go button—for example
when you are satisfied with the current detect levels for the X and R signals.
8)
When the auto-calibration procedure is complete, the Main Menu reappears.
Currently (as shown in the screen below) the detect level is 554 for the X signal and
488 for the R signal.
