value is +30% (with the exception of collective pitch
trim for helicopters).
'' TIP:
If you reverse a transmitter control, you must also
reverse the direction of the trim. Open the trim travel
adjust field and reverse the direction of effect by
pressing the y button. You will see that the prefix
symbol for trim travel changes.
„-10%“ means that the trim has been reversed.
5. Second independent
memory block (optional)
This is how it used to work:
The PROFI mc 4000’s model memory could store
data for 25 to 100 models depending on their com-
plexity. Many users exhausted even this capacity and
were obliged to store settings for rarely used models
on their PC. This is a good idea in any case, as it al-
lows the experimentally minded modeller to fall back
on the „last properly working version“ of a particular
model when a new variant turns out to be a bad
choice.
This is how it works now:
If you have this option installed in your transmitter,
two independent model memory blocks of equal size
are available to you. Memory capacity now rises to
50 to 200 models.
This is how it’s done:
You select which of the two memory ranges you wish
to use in Power-on menu 3.
Assuming that the memory expansion module has
been installed in your transmitter, this is the proce-
dure:
• Switch the transmitter on with
the k button pressed in
• Press the q button twice
This menu should now appear:
Power-ON menu 3

If the bottom line does not appear on your screen,
then the second memory module is not present.
• Open the select field with the w button.
• Select the module you wish to use with the q/n
buttons or the Digi-adjustor.
• Press k, k to return to the operating screen. The
selected module is now active.
'' TIP:
Don’t be alarmed if your transmitter now switches it-
self off briefly. Switching to the other memory module
initiates a complete „re-boot“ (re-start). This includes
saving the data, so you will also see the message
„Saving data!“ on the screen.
Interrogating the active memory module:
If you want to know which module is currently active
in your transmitter, simply move to the Memory
menu. From the operating screen you reach this with
w w. The top line of the screen displays the number
of the currently active memory module.

6.1 SLOW for mixer inputs
(formerly SOFT-SW)
This is how it used to work:
Mixer inputs could be switched „gradually“, but the de-
lay time was only effective during the switching proc-
ess itself. If you only switched on the input in question
once, then the set delay had no effect, i.e. the trans-
mitter control signal was passed to the servo without
any delay.
This is how it works now:
This facility has been expanded into a genuine
SERVO SLOW function. The actual switching process
still works „SLOWly“, but the function’s response to
commands from the associated transmitter control is
also affected, and works at the SLOW rate which you
have set.
In the new software the SLOW time you have set al-
ways applies, i.e. the response to the transmitter con-
trol is delayed when switching on, switching off and
when the transmitter control is operated. It is in fact a
proper SERVO-SLOW function. The set delay time
therefore only affects the selected mixer input on the
selected servo.
This new method of operation clearly required a new
designation, and that is why we have changed the
menu point’s label from Soft-SW to SLOW.
