In this menu you can adjust parameters which only af-
fect the servo connected to a particular receiver output,
namely the direction of servo rotation, neutral point and
servo travel. Always start with the servo setting in the
left-hand column.
Basic procedure:
1. Select the relevant servo (1 to 8) with the rotary cylin-
der held pressed in.
2. Use the rotary cylinder to select SEL, SYM or ASY in
the bottom line, prior to making the adjustments re-
quired.
3. Press ENTER or the rotary cylinder: the correspond-
ing input fi eld is highlighted (inverse video).
4. Set the appropriate value using the rotary cylinder.
5. Finally press ENTER or the rotary cylinder again to
conclude the input process.
Important:
The numbers in the servo designations refer to the
receiver output socket to which a particular servo(s) is
connected, assuming that these have not been swapped
over. This means that changing the stick mode does not
affect the numbering (i. e. receiver socket sequence) of
the servos.

Column 2 "rev"
The direction of servo rotation can be adjusted to suit
the actual installation in your model. This means that
you don't need to concern yourself with servo directions
+
trav
when installing the mechanical linkages in the model,
as you can reverse them as and when necessary. The
direction of rotation is indicated by the symbols "=>" and
"<=". Be sure to set the direction of servo rotation before
you make adjustments to the remaining options!
Pressing CLEAR

resets the direction of rotation to "=>".

Column 3 "cent"
The facility to offset the servo travel centre is intended
for adjusting servos whose centre setting is not standard
(servo centre point at 1.5 ms), and also for minor adjust-
ments, e. g. when fi ne-tuning the neutral position of the
model's control surfaces.
The neutral position can be shifted over the range
-125% to +125% of normal servo travel, within the maxi-
mum servo travel of ±150%, regardless of the trim lever
position and any mixers you have set up. The setting
affects the associated servo directly, independently of all
other trim and mixer settings.
However, please note that an extreme shift of the servo's
neutral point may result in servo travel to one side of
neutral only, as total servo travel is limited to ±150% for
both electronic and mechanical reasons.
Pressing CLEAR resets the value to "0%".
