30 Transmitter description - Hidden mode
Wait for the notices which typically appear in the base
screen following a model change then jump to the
"
Servo display " menu, for example by simultaneously
touching the

keys of the left touch pad (WITHOUT
any interim change to trim settings or other program
settings).
If all four of your transmitter's joystick functions are still
self-neutralizing, this display should ideally look like the
one shown below.

Otherwise the graph bars show current setting
percentages for joystick control functions which are not
self-neutralizing – typically for the "K1", throttle/brake or
throttle/pitch, control stick. For example, if the throttle/
brake control stick is in its "quarter-throttle" position, the
display would appear as shown below.

One after the other, put both joysticks into each of their
four possible limit positions
without exerting force at
the limit position. In each of these eight possible limit
positions, the – side dependent – indication for exactly
-100 % or +100 % should be displayed. For example,
if Control 2 is at its left limit and the other three joystick
functions are in their respective middle positions then
your transmitter's display should look like the one shown
below.

Regardless of the number of self-neutralizing joystick
functions available on your transmitter, if these checks
produce four 0 % results and eight 100 % results then
your transmitter's joysticks are optimally calibrated. You
can terminate this process then, if appropriate, delete
the model memory just created.
Otherwise jump (as described at the outset of the
previous double page) to the "Stick cali." line in the
"
HIDDEN MODE " menu then briefl y touch the center
SET key in the right touch pad.

… and briefl y touch the center SET key in the right

Now release the self-neutralizing joystick so it can return
to its center position and then tap again on the center
SET key to calibrate the joystick's centered position. The
right arrow marker will begin to blink.
