15. It is possible to adjust the scenario parameters without changing the stored
parameters within the Setup Menu. With the UUT FUNCTION switch in the TCAS
position and with the TCAS scenario window displayed, proceed as follows:
15a. Ensure that pressing the TO/STAR-FROM/STOP switch up twice and the
display stop the scenario shows STP. (This is the only position, which
allows temporary modification of the scenario parameters)
15b. By switching the CHN/ALT-DIST-SPEED switch to the relative positions,
the altitude, distance and speed of the intruder can be adjusted with the
UP-DOWN switch. Intruder velocity can be changed with the
INCREASE-DECREASE VELOCITY switch. The scenario can now be
run again with the modified parameters.
