In the default state of the mc-22s transmitter this
menu is initially suppressed. To activate it, move to
the »
Suppress codes « menu (see page 49), or set
this menu point to “yes” in the » Basic settings «
menu (see page 117) before you set up a new model
memory.
In the previous menus – » Phase setting « for helicop-
ters and fi xed-wing models – you have already defi -
ned names for the fl ight phases. In this menu you now
have to determine the switch or switch combinati-
ons by which you want to call up each phase. There is
one exception to this rule in the Heli menu: you must
set one of the two auto-rotation switches in the »
Au-
xiliary switch « menu.
Please note the following priorities:
• The auto-rotation phase (Heli mode only) always
(!) has precedence, regardless of the switch set-
tings of the other phases. As soon as the auto-ro-
tation switch is operated, this display appears on
the screen:

Autorot
• Phase switch “A” has priority over all subsequent
switch settings “B” to “D”.
For this reason you should only use switch “A” if you
wish to change from any other fl ight phase – apart
from auto-rotation – directly into the phase which is
assigned to this switch.
Programming the fl ight phase switches
The external switches (or software control switches)
are assigned in the usual way. The sequence of assig-
ning them is unimportant; you simply have to ensure
that you assign the “right” switches for your own pur-
poses. In the Heli program it is therefore important
to check that you do not accidentally assign a switch
a second time which you have already assigned as
the auto-rotation switch in the »
Phase assignment «
menu.
Example: fi xed-wing model with phase priority for
four phases
You require (typically) two simple ON / OFF switches,
e.g. Order No.
4160 or 4160.1.

Assign the switches using the rotary control, then
move to the
SEL fi eld and assign a phase name to
each switch position or combination of switch positi-
ons; the phase names are selected from the »
Pha-
se assignment « menu; for example «1 normal», «2
launch», «3 distance», «4 landing».
It makes sense to assign the closed (“I”) priority
switch “A” to the phase into which you wish to switch
directly, regardless of the positions of switch “B” and
“C”, e.g. the “Launch” phase, if the same switch is
used to switch an electric motor on, or into the “nor-
mal” phase … e.g. in an emergency. When switch “A”
is open (“ ”) you can select the remaining three pha-
ses for the switch positions “B” and “C” to suit your
own preference; see table below.

or
I «2 Launch»
«1 Normal»
I «3 Launch»
I «4 Landing»

not in use; i.e. by de-
fault: «
1 Normal»
In this example the three external switches 1, 2 and 3
have been assigned (in accordance with the numbe-
ring in the »
Switch display « menu); these switches
are fi tted as standard in the centre console.
You are now in a position to make the required adjust-
ments in all the phase-specifi c menus.
Tips:
Instead of the two individual switches connected to
sockets 2 and 3 you could use the optional differenti-
al switch (three-position switch), Order No.
4160.22 .
If you use fl ight phases regularly, we recommend this
option in preference to individual switches, as it is
then easier to distinguish the selected fl ight phase at
a glance.
It can also be particularly useful to exploit the tra-
vel offset adjustment facility in the »
Control adjust «
menu:
For example, you may like to select different camber-
changing fl ap settings for the fl ap servos (receiver
outputs 6 + 7) and for the aileron servos (receiver out-
puts 2 + 5) for each fl ight phase.
Select the “Offset” column and adjust the values for
the ailerons and fl aps where they vary from the “nor-
mal” fl ight phase. Please remember this rule:
