… – see previous fi gure – set the mixer's neutral •
point automatically back to control center with a
simultaneous tap on both the cd or ef selection
keys of the right touch pad (CLEAR).
Symmetrical mixer ratios
The next task is to defi ne the mixer values above and
below the mixer neutral point – starting from its current
position.
If necessary, use selection keys ef on the left or
right touch pad to select the SYM fi eld in order to
establish a mixer value which is symmetric to the
offset point just set. Following a brief tap on the
center
SET key of the right touch pad, set both SYM
fi elds (now in inverse video) via the selection keys
of the right touch pad to values between -150 % and
+150 %. Note that the mixer value set always refers
to the input signal of the respective transmitter control
(control signal)! Negative mixer values reverse the
direction of the mixer.
A simultaneous tap on the cd or ef selection keys
of the right touch pad (CLEAR) will erase the mixer
ratio in the inverse video fi eld.
The "optimum" value in our example will certainly
need fl ight-testing.

Earlier, we set the mixer neutral point at -75 % of
control travel: as a result, the elevator ("EL") will
exhibit a (slight) down-elevator effect even at the
neutral point of the landing fl aps and this is naturally
undesirable. Accordingly, you should reposition the
mixer neutral point to -100 % of control travel, as
described earlier.

If the offset, now -100 %, is reset to 0 % of control
travel by using selection key f on the left or right
touch pad to select the SET fi eld then tapping either
the selection key combination cd or ef on the right
touch pad (CLEAR), the following screen will appear:

Asymmetric mixer ratios
In many cases, however, we require different mixer
values on each side of the mixer neutral point.
Do this by fi rst resetting the offset of the mixer used
in the example, "6 ¼ EL" again to 0 %,if necessary,
refer to the fi gure above. Now select the ASY fi eld
with the selection key f on the left or right touch
pad then tap the center
SET key of the right touch
pad. If slider control SR1, assigned to input 6 in
this example, is now moved in each corresponding
direction, the mixer ratios for each of the two control
directions, i.e. left and right of the established offset
point, can be adjusted with the selection keys of the
right touch pad:
