Program description - Helicopter mixer
The order in which up to six reference points are
generated between the end-points "L" and "H" is ir-
relevant since these reference points are continuously
renumbered automatically from left to right as they
are entered.
Conguring reference points
To configure a point, use the stick to move the vertical
line onto the point you wish to change. The number
and current curve value of this point are displayed on
the left side of the display, on the "Point" line. Briefly
tap the centre SET key of the right touch pad. Use the
selection keys on the right touch pad to change the
current curve value shown in the highlighted field. The
possible range is -125 % to +125 % and changes do
not affect neighboring reference points.

In this sample screen image, reference point "1" has
been set to +75 %.
If you wish, however, other points can also be set. At

… or, reset again with a simultaneous tap on the 
or  selection keys of the right touch pad (CLEAR).

Alternatively, a jump up or down to reference points
already set, L, 1 … max. 6 and H, can be accom-
plished by using the  selection keys on the left
touch pad.
The selection keys on the right touch pad can then
be used to change the reference point jumped to as
described above, entirely independently of the control
position.

In this simple example, the pitch stick – represented by
the vertical line – is halfway between "Pitch minimum"
and the midpoint of control travel (input = -50 %). How-
ever, "Point 1" will be relocated to control centre at a
point value of +50 %, resulting in a momentary output
value of -25 %.
One touch on the centre ESC key of the left touch
pad terminates this trim point function.
Trim offset function
When a value field is active, i. e. in inverse video, it is
not only possible, as previously described, to jump up
or down to reference points already set with the 
selection keys of the left touch pad and to make a
change with the selection keys of the right touch pad,
but also an existing curve can be vertically reposi-
tioned within a range of ±25 % through use of the 
keys on the left touch pad. Starting with a point value
for "Point 1" at 0 %, the control curves in both of the
following figures have been vertically shifted within the
±25 % range by the trim offset function:
