PILOT EVENT MARKER
At any time a full set of BITE parameters can be recorded by going in
and out of variable gain four times (pull GAIN knob for VAR, push for
preset, pull for VAR, and push for preset) within three seconds. There
is no annunciation on the display after this operation.
This feature can be useful if the radar appears to be malfunctioning and
a fail annunciation is not shown on the display. If the pilot event marker
is used, it is best to record several sets of data during the period of
misoperation. Refer to the PRIMUS
