Trim point function
Alternatively, you can skip reference points L, 1 …
max. 4 and H in the active (i. e. highlighted) Value field
using the Select buttons  of the left-hand four-way
button in the ascending or descending direction. The
selection keys on the right four-way button can then
be used to change the reference point jumped to as
described above, entirely independently of the control
position, for example:

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 %). However, “Point 1” will be relocated to control
center at a point value of +50 %, resulting in a mo-
mentary output value of -25 %.
One touch on the center ESC key of the left four-way
button 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 four-way button and to make
a change with the selection keys of the right four-way
button, but also an existing curve can be vertically
repositioned within a range of ±25 % through use of
the  keys on the left four-way button. 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 func-
tion:

A tap on the center ESC key of the left four-way but-
ton will also terminate this function.
Trim x-axis function
This function is activated by tapping the left () or
right () selection key of the right four-way button
with an active (i. e. inverse video) value field. You can
then use the selection keys on the right four-way but-
ton to reposition the active point horizontally or verti-
cally as you wish. In the figure below, “Point 1” which
was just shifted to +25 % with the trim point function,
will now be shifted to the left:

Notes:
• If the point is repositioned horizontally further
away from the current control position than approx.
±25 %, a “?” sign will reappear in the line Point.
This question mark does not refer to the reposi-
tioned point, however: instead, it signifies that a
further point can be set at the current control po-
sition.
• Please note that the percentage value on the “Out-
put” line always relates to the current stick position
and not to the position of the point.
