To do so, use the joystick to move to the
corresponding area. As soon as a "?" appears in the
marker frame on the "Point" line, the respective point
can be set by touching the selection keys of the right
touch pad. Just as with other points, this can be set

... or, reset again with a simultaneous tap on the

The "L" and "H" points, on the other hand, CANNOT
be deleted.

Alternatively, a jump up or down to reference
points already set, L, 1 ... max. 6 and H, can be
accomplished 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 joystick – 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 momentary output
value of -25 %.
One touch on the center
pad terminates this trim point function.

not only possible, as previously described, to jump

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
repositioned 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 fi gures have been vertically shifted within
the ±25 % range by the trim offset function:

Trim x-axis function
This function is activated by tapping the left ( ) or
right ( ) selection key of the right touch pad with
an active (i.e. inverse video) value fi eld. You can
then use the selection keys on the right touch pad to
reposition the active point horizontally or vertically as
you wish. In the fi gure below, "Point 1" which was just
shifted to +50 % 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
repositioned point, however: instead, it signifi es
that a further point can be set at the current
control position.
