1.1 Concept of the PROFI TX
When we initially mapped out the basic philosophy of the PROFI TX, we placed
particular emphasis on providing a high level of user-friendliness, flexibility and the
greatest possible standardization.
User-friendliness is achieved thanks to the clean overall menu structure,
informative and clearly arranged menus and many other useful features which
facilitate programming and operating the transmitter.
Flexibility is guaranteed because you can implement almost any customisations to all
pre-defined "ready for use" elements. Controls (sticks, sliders and switches) and
servos can be assigned freely. Pre-defined mixers can also be adjusted as required.
Thanks to pre-defined model templates, you need to press only a few buttons to
store your model in the memory and start operating it.

Read the instructions carefully!
Make sure that you have carefully read these operating instructions and the
following safety instructions before setting up the device for operation.
Radio-controlled models are not toys in the usual sense. Assembly, installation, and
operation of the RC system require technical knowledge, care, safety-awareness
and responsibility. Errors or negligence can lead to considerable damage. Since the
manufacturer or the seller does not have any influence and control over the proper
setting up and operation of a model, such risks are expressly pointed out here and
any liability whatsoever is excluded.
A model that goes out of control for whatever reasons can cause significant damage
to property or personal injury. Be aware of safety at all times. Make sure to take out
general liability insurance.
Do not modify the radio control system. Use only original accessories and spare parts.
If the device is operated in combination with third-party products, ascertain their
quality and functional reliability. Each new or changed combination must undergo
careful functional testing, including a range check. Do not operate the device or
model if there appear to be any problems. First identify the error and troubleshoot it.
In particular, have the radio control transmitter and the receiver inspected at an
authorised MULTIPLEX Service Centre (see section 10.1 "Specifications" on
page 212) at regular intervals (every 2 to 3 years).
Operate the transmitter only in the permissible temperature range (see section 10.1
"Specifications" on page 212). Bear in mind that condensation may form in the
transmitter due to sudden temperature changes (e.g. warm car, cold environment).
Moisture may impair the function of the transmitter and other components of the
radio control system.
2.1 Basic safety instructions
The following basic safety instructions and warnings are an essential component of
these operating instructions and are fundamentally important for device handling.
Page 16
Safety instructions
Page 14
PROFI TX
If moisture accumulates in electrical devices, immediately stop using the device,
disconnect it from the power supply and allow it to dry in the open state as far as
possible (up to a few days). Thereafter, perform a careful functional test. In case of
major condensation, have the device inspected at an authorised MULTIPLEX
Service Centre (see section 1.2 "Contact" on page 9).
Caution: static electrical charges!
In extremely dry air static charges tend to build up in the transmitter and / or the
pilot. The discharge takes the form of static sparking which can cause interference
or damage to the transmitter and other components of the radio control system.
Operation of the radio control system is allowed without restrictions within EU
territory and Switzerland.
Program a new model at home in peace. Make sure that the power system of the
model cannot start up unexpectedly. Check all functions carefully. Completely
familiarize yourself with the operation of the transmitter before putting the model
in operation.
Page 17
Safety instructions
PROFI TX
Page 15
The transmitter battery is responsible for the power supply to this device, and plays
an important role in operational safety. The charging circuit integrated in the
transmitter matches the battery. Do not charge the battery outside the device.
Batteries are not toys and must be stored out of the reach of children.
Damaged or defective batteries must not be used and should be disposed of
properly (see section 2.8 "Disposal" on page 22).
Do not heat, incinerate, open or short-circuit rechargeable batteries, do not charge or
discharge them at excessive currents, do not overcharge them, and do not charge
with reversed polarity. Take note of the admissible temperature range for the battery.
Mis-handling the battery incurs the risk of combustion, explosion, corrosion and
burning.
2.2Safety instructions for the transmitter battery
Page 18
Safety instructions
Page 16
PROFI TX
The sub-assemblies of radio control transmitters (main circuit board, RF module,
Channel-Check module, Scanner module) are fitted with electrostatically sensitive
components. These parts can be destroyed, suffer imperceptible damage or have
their useful life shortened if static discharges take place (potential equalisation
through electro-static discharge) when the sub-assembly is touched.
2.3ESD notes for electronic sub-assemblies
The following protective measures are essential if you have to handle electrostatically sensitive sub-assemblies:
Before fitting or removing such sub-assemblies, equalise the electrical
potential difference between yourself and your environment (e.g. by touching
a heating radiator).
Open the basic device and touch it over a large area in order to equalise the
potential relative to the base unit.
Do not remove any sub-assemblies from their conductive anti-static bags
until you have equalised the potential. Avoid touching electronic components
or solder pads directly. Hold the sub-assembly by the edges of the circuit
board only.
Once removed from the basic device, the sub-assembly should only be
stored in the conductive anti-static bag in which it was delivered. Never allow
the sub-assembly to make direct contact with a conventional, non-ESD
compatible container made of foam, Styrofoam or other plastic.

1. Transmitter
2. Receiver
3. Connect the flight battery or switch the power system ON
Switching off
1. Disconnect the flight battery or switch the power system OFF
2. Receiver
3. Transmitter
2.4Intended use
The PROFI TX transmitter is intended exclusively for operation of models by
radio control.
Assemble the model carefully
Install and adjust all control surface linkages in such a way that the surfaces
move smoothly and freely, and are not stalled even at maximum travel. Don’t
use the transmitter to regularly limit servo travels. It is always better to adjust
levers and pushrods mechanically and as thoroughly as possible. Avoid lost
motion (sloppy linkages). Use configuration options on the servo side of the
transmitter only for fine-tuning.
The measures mentioned above are essential in order to minimise the load on
the servos.This in turn allows them to perform at their best, and they will also
last longer and operate more reliably.
Provide effective protection from vibration to the receiver, battery, servos
and other RC and electronic components. Observe the advice included in
the relevant operating instructions. Balance propellers and rotor blades
before use and replace them at any sign of damage. Install I.C. engines
on vibration-absorbing mounts and replace motors or motor parts which
are damaged or do not run true.
Do not strain or bend cables; protect them against rotating parts.
Avoid unnecessarily long or superfluous servo extension cables.
Page 20
Safety instructions
Page 18
PROFI TX
Observe also the advice included in the relevant receiver operating instructions!
Use cables with sufficient cross-section.
Do not coil up or shorten the receiver aerial. Do not lay the aerial on or close
to electrically conductive components. Deploy aerials outside of fuselages
with a shielding effect (carbon fibre, metallic painted finish).
Ensure that the receiver power supply is of adequate capacity. For servos up
to about 40 Ncm torque you can estimate the required battery capacity using
the following formula:
Capacity [mAh] ≥ servo count x 200 mAh.Use the next larger size of battery!
Take care to maintain sufficient distance between cables carrying heavy
currents (e.g. electric power system) and the RC system. Especially the
cables between brushless electric motors and their actuators must be kept
as short as possible (guide value: max. 10 to 15 cm).
Check the model regularly
Free movement and zero backlash of rudders and linkages.
Stability and flawless condition of rods, linkages, hinge joints, etc.
Carry out a visual check for fractures, cracks, possible shear points etc. on
the model itself, and in its components such as the RC and power systems.
Flawless condition and contact stability of cables and plug connections.
Absolutely essential: Examine the power supply and its wiring, including the
switch harness, and the external condition of the battery.
This entails regular maintenance of the battery and periodic checks of the
voltage curve and capacity, employing a charge process and battery charger
suitable for the type of battery in use.

If you discover any irregularities, do not fly. Locate the problem, eliminate it, and
then check again.
Pre-flight checks
Charge the transmitter, receiver and flight batteries carefully, and verify their
state of charge at regular intervals.
Ensure that the correct model memory is active.
Carry out a range check (see section 3.6 "Range check" on page 47).
Check the function and effect of all primary and secondary control systems.
When operating the model:
If you have never flown a radio-controlled model before, it is highly
recommended you consult an experienced model pilot when getting started.
A trainer (buddy-box) system is ideal for taking the first steps in learning to fly.
Models should only be operated at suitable sites.
Never fly or drive over or towards spectators.
Do not carry out any high-risk flying or driving manoeuvres.
Know your limits: do not over-estimate your abilities and skills.
If you detect any sign of a problem or interference, land or cease operations
immediately.

2.5 Liability and indemnification
The model sport with radio-controlled models is a fascinating hobby. However,
model aeroplanes, vehicles and ships are not toys. Their assembly and operation
require a high level of technical knowledge, careful craftsmanship, safetyawareness and responsibility. Errors, inattentiveness or even negligence can
lead to considerable damage to property or severe personal injury. Generally, you
as operator are responsible for any threat arising from your model. This absolute
liability will not be assumed by the manufacturer. This is also applicable in the
event of uncontrollable external influences and interferences. You are expected
to exercise extreme care as operator of a model.
Since manufacturers or dealers cannot have any influence on proper setting up,
maintenance and operation of the model and the radio control system, such risks
are expressly pointed out here.

(see section 10.2 "Accessories" on page 213).
To install a new stick top, proceed as follows:
1. Switch off the transmitter and open it.
2. Remove the battery1.
3. Loosen the grub screw at the bottom of the stick top (1.5mm slot-head
screwdriver).
4. Pull off the top from the stick shaft.
5. Wrap the flexible wires of the new stick top with a thin enamelled copper wire.
Tightly bend back the insulated section. Thread the wire through the threaded
coupler of the stick shaft until it is visible at the bottom of the stick unit. Use a
pair of pliers to pull the wire out until you can grab it with your fingers.
After re-inserting the battery, the date and time need to be set again.

6. Gently pull on the wire until you can grab the flexible wire with your fingers.
This will be easier if you turn the stick shaft on the side opposite the point
where the wire exits.
7. Slide the stick top onto the stick shaft, simultaneously pulling the flexible wire
completely through.
8. Tighten the grub screw on the stick top.
9. You can see one three-pin terminal clamp next to every stick unit on the main
circuit board of the transmitter. Remove the wire.
Clamp the blue flexible wire to the centre terminal and the red wire(s) to the
output terminal(s).
10. Insert the battery and close the transmitter.
11. Switch on the transmitter.
12. Verify that the switch operates correctly.
To test this, assign the new stick switch to any switched function in the Setup >

To install a module proceed as follows:
Page 43
Transmitter
PROFI TX
Page 41
The trans mitter must not be connected to a charger when no battery is installed!
Without a consumer, the charger can provide unacceptably high output voltages.
These voltages can damage the transmitter.
3.4 Transmitter battery
The PROFI TX is powered by a very robust and durable LiFePO4 battery.
The battery is installed with the electronic system for battery management in a
welded case. If the battery is new, the battery capacity of 4000mAh provides an
uptime of more than 25 hours. Additionally installed components increase power
consumption and shorten the operating time. If the device is exposed to very low
temperatures, the operating time is significantly reduced.
3.4.1Charging the battery
The PROFI TX features two USB sockets at the front on the right-hand side of the
case, which are protected by a sliding latch. The mini USB socket is used for
charging (see section 3.1.5 "Connections" on page 29).
The following options are available for charging the PROFI TX:
Via your PC or laptop
Via the MULTIPLEX USB car plug-in charger 12V DC
(item no. 145533)
Via the MULTIPLEX USB plug-in charger 100-240V AC
(item no. 145534, see section 10.2, "Accessories" on page 213)

When used for the first time, the PC automatically installs the required device
drivers. Do not switch off the PC and/or the transmitter and do not disconnect the
USB cable while the installation is in progress. This may take several minutes.
Some operating systems require an active Internet connection for this process.
3.4.1.1 Charging the battery via the PC
Proceed as follows:
1. Switch off the PROFI TX.
2. Lift the device. The recessed control for the sliding latch is located on the
underside of the case.
3. Slide the sliding latch towards the device centre.
4. Switch on the PC or laptop. Connect the supplied USB cable to a USB socket
on the PC and to the mini USB socket on the PROFI TX.
o The PROFI TX starts automatically in charging mode.
o The USB icon is shown on the right side of the screen and the
state of charge and the charging current are displayed on the left.
Maximum current: 500 mA.
The PROFI TX logs into the PC as mass storage with the name
"PROFI TX".
If you press and hold the Power button until the annular light is fully lit, the
transmitter switches from charging mode to normal mode. The PROFI TX logs off
from the PC as USB mass storage and logs in again as a game controller
(see chapter 7 "Operating the transmitter " on page 174).
The RF module is disabled while a USB connection is established. It also remains
switched off after disconnection. Otherwise, the RF module would be re-enabled
when the host (PC, laptop, etc.) is switched off.

Charge the transmitter battery!
If voltage is low, recharge batteries as soon as possible (within 1-2 days) to avoid
damage due to total discharge. Observe the notes on charging (see section 3.4
"Transmitter battery" on page 41).
3.4.4Battery management
The PROFI TX records the current during transmitter operation and while loading
the transmitter battery. The available battery charge is calculated on the basis of
the power meter reading, the temperature and the voltage. The remaining
operating time (time to empty) is calculated from charge and current and is shown
on status display #2 (see page 87). The calculation takes into account that current
consumption slightly decreases with decreasing battery voltage.
Battery alarm
If the remaining operating time (time to empty) falls below the set threshold,
an audible alarm is issued. The respective displays flash on status display #2.
The factory setting for the alarm threshold is 60 minutes. This value can be
changed in the Setup > Transmitter > Battery alarm menu (see section
5.3.8 "Transmitter" on page 109).
Self-discharge
If the transmitter is stored for a prolonged period, the available battery charge is
calculated on the basis of multiple parameters when the transmitter is switched on.
The displayed charge and time to empty are not initially very accurate. Precise
values are displayed after a few charging / discharging cycles.
Under-voltage cut-off
If the operating voltage falls below 2.8V the device is automatically switched off
without further warning. If the voltage is below 2.9V, it cannot be switched on:
The following message is briefly displayed on the screen: BATTERY DOWN!
Page 47
Transmitter
PROFI TX
Page 45
Charge the transmitter battery!
The PROFI TX is supplied with a partially charged transmitter battery. You should
charge the battery prior to setup. Observe the notes on charging (see section 3.4
"Transmitter battery" on page 41).
If you press and hold the Power button for a prolonged period, the annular light turns
off again and the device is not switched on when you release the button (power-on
protection).
The RF module is switched off until the safety check is completed to prevent the
servo from moving to an undesired position.
3.5 Switching the transmitter on / off
3.5.1Switching on
To switch on the device proceed as follows:
1. Press and hold the Power button until the annular light is fully lit. The device is
switched on when you release the button.
2. At this point, either a confirmation prompt is displayed on the screen:
Or the language selection screen is shown, if the menu language has not yet

Switching on in Binding mode
Press and hold the ¡ button until the status display is shown (see section
"Binding" on page 48).
Switching on for range check
Press and hold the § button until the status display is shown. The device starts up
with reduced transmitting power when the range check is performed (see section 3.6
"Range check" on page 47).
Switching on for the first time
The very first time you switch on the PROFI TX is a special case. After switching
on, the language selection menu is displayed on the screen. In this menu, you
select the language used on the transmitter to display
1. the menus,
2. the names of mixers and control functions in the model templates.
The language is selected using the keypad (up/down/ENTER). If you select
"skip/später", transmitter functionality is restricted: Only one model memory is
available and its contents are not stored on the SD card. The menus are shown
in English.
3.5.2Switching off
Press and hold the Power button until the red annular light turns off completely to
switch off the device. The device is switched off when the annular ring turns off and

Recommended minimum distance: 40m to 100m, depending on receiver type. Refer
to the receiver operating instructions for detailed information.
Always perform a range check before starting up the model.
A second person must always be present for the range check to secure and observe
the model.
Large metal objects within or in close proximity to the checking range (wire fences,
cars) affect the result of the range check.
3.6 Range check
Regular range checks are necessary for ensuring the reliable functioning of the
radio control system and for timely detection of changes in transmission properties.
Always perform a range check after:
installing, modifying or rearranging components in the model,
reusing components in the model that were involved in a crash,
irregularities when operating the model.
When performing a range check, the transmitting power is significantly reduced
enabling shorter distances between transmitter and model.
While the range check is active the status displays #2 to #8 show the flashing
message: RANGE! with the annular ring flashing red. An alarm tone is emitted in
all the status displays starting from #2 to alert the operator.

Procedure
1. If the model is fitted with a power system, switch it off!
2. Press and hold the ¡ button on the transmitter as you switch the transmitter on.
3. Switch on the receiver.
4. In the Servo > Test run menu, activate the test run for a control function,
e.g. Elevator. This allows you to check that the receiving system responds to
control commands with distinct, regular movements of the control surfaces.
5. Increase the distance between transmitter and model. You have reached the
range limit when the servos start to jitter.
6. Repeat the check with the power system running. Secure the model. Perform the
check using throttle positions that vary between idle and full throttle. In case of
electric power systems, the most significant interferences occur at half throttle.
The range should not diminish significantly.
7. Otherwise, eliminate the cause of the interference (engine or motor, installed
position of the receive system, power supply).
Factors influencing the radio range
The following factors have significant influence on the radio range:
Environmental conditions
Hilltops, ground characteristics, type of terrain, and the atmospheric
conditions affect radio range.
Receiver technology and sophistication
Technically sophisticated receivers have greater range than simple, cheap
receivers.
Radio installation in the model
Installation position / arrangement of the aerials and the distance to
batteries, power systems, servos, ignition systems, metal / carbon fibre parts
influence the radio range.
Binding
The binding procedure binds the receiver with the transmitter.
M-LINK uses "frequency hopping" and "spread spectrum".
No fixed transmission channel is used for "frequency hopping", but all 39 channels
are used in a sequence that is defined by the transmitter.
Page 51
Transmitter
PROFI TX
Page 49
If the binding procedure does not automatically complete within a few seconds,
move the transmitter front closer to the receiver aerial(s).
For "spread spectrum", every data bit is coded in 64 bits (spread). This procedure
provides a high level of interference resistance. During binding, the transmitter
passes "hopping sequence“, "spreading code", and "response time" to the receiver.
Procedure
1. Press and hold the tool button and switch the transmitter on. Once activated,
the safety check display is shown. Follow the instructions shown.
o The (flashing) message "BINDING" is shown in the status displays #2 to #8.
o The annular light of the Power button is flashing in orange.
2. Switch on the receiver by pressing and holding the SET button (connect the
power supply).
The receiver LED is flashing rapidly.
The binding procedure is completed within a few seconds:
o The annular light returns to flashing yellow.
o The receiver LED is flashing slowly.
o The servos that are connected to the receiver can now be controlled.

If the radio link between the student and the teacher is interrupted, all the control
functions are returned to the teacher.
3.7 Trainer mode
The trainer mode (teacher / student) is the safest method for beginners to get
started in model sport.
An experienced model pilot has control over the model as the teacher. The trainer
can transfer control functions to the student by operating a button. Initially these will
be individual control functions, and later all the main control functions.
The PROFI TX can be configured either as a teacher transmitter or as a student
transmitter. The teacher and student transmitters are inter-connected using a
second M-LINK radio link.
Student mode
In Student mode, the control signals of the sticks and sliders are transferred via
M-LINK to the teacher transmitter (without trim and travel settings).
A second PROFI TX with COPILOT module or another MULTIPLEX transmitter
with trainer stick can be used as the teacher transmitter.
Refer to "Training" on page 96 for details.
Teacher mode
A free switch on the teacher transmitter and the COPILOT module are required for
the Teacher mode (see section 10.2 "Accessories" on page 213):
Refer to section 3.3.4 "Installing additional controls" on page 37 for
installation instructions.
The assignment of the switch to the trainer function is described in section
6.4.2 "Assigning switches" on page 171.
Refer to section 3.3.5 "Installing additional modules" on page 40 for
information on how to install the COPILOT module.
In Teacher mode, the selected control functions can be controlled by the student
transmitter. These control functions are selected in the Setup > Training menu.
The selection list is only available in Teacher mode.

3.8Digital trim
3.8.1Overview
"Trimming" refers to the adjustment of the model aircraft to fly straight and level
when you leave the sticks exactly at centre.
Digital trim has two essential advantages:
The physical position of a conventional trim with trim slider corresponds to the
actual trim value, while digital trim buttons do not. The digital trim position is
displayed on the screen, and any change to the trim values is stored in the
model memory. If you switch model memories, there is no need to move the
trim sliders to the correct position to suit the model. The correct trims are
immediately available.
In models for which you have set up multiple flight phases each flight phase
has its own trim memory, i.e. it is simple to trim each flight phase accurately,
and independently of the trims in the other phases.
Example
The model aircraft should fly straight and level when you leave the sticks exactly at
centre. If this is not the case, the neutral point of the causal control function should
be corrected / trimmed.
Centre trim
The PROFI TX enables digital trim on each of the four stick axes.
"Centre trim" (the centre trim principle) is applied to the main control functions
"Aileron", "Elevator", and "Rudder". The trim only affects the control centre, but not
the end-points. Unlike standard trim, this offers the advantage that no control travel
must be reserved for trimming: the servo travel is used fully.
Both servo end-points remain unchanged, regardless of the current trim position.
3.8.2Trim buttons
In the case of the PROFI TX, trimming is carried out using the buttons arranged
below and to the side of each stick unit (see section 3.1.1 "Top view" on page 23).
They are located in an ergonomically efficient position, and are easily reached
when using the transmitter, whether hand-held or in a tray.
The effect of each button-press is to shift the trim of the associated control axis in
the corresponding direction. If you hold the trim button pressed in for longer than
Page 54
Transmitter
Page 52
PROFI TX
Switching the step size changes the trim value percentage since the number of
stored trim increments remains the same. This means if you alter the trim increment
size, you must remember to re-trim the model.
about 0.8 sec., the trim value changes continuously until you release the button
again (AUTO-REPEAT function). When the trim reaches centre, the AUTOREPEAT function stops briefly.
Each trim increment is accompanied by an acoustic signal. On reaching the trim
centre and on reaching the maximum trim range, specific acoustic signals are
emitted to alert the user. The volume of the acoustic signals during trimming can
be configured in the Setup > Transmitter > Volume menu (see section 5.3.8
"Transmitter" on page 109).
3.8.3On-screen trim display
Graphic display
The trim positions are displayed as bars at both sides and at the bottom of the
screen in the status displays #2 to #8:
Fig. 7: On-screen trim display
Starting from the trim centre position, the trim range is 20 increments in both
directions. The trim increment (step, or adjustment rate) can be set to any of four
values (0.5%, 1.5%, 2.5%, 3.5%) (ControlFunctions > respective control function, Step size parameter, see section 5.4 "ControlFunctions main menu"
on page 112).
The design of the graphic trim display can be selected (Setup > Transmitter >
Display, Trim graph parameter, see section 5.3.8 "Transmitter" on page 109).

Switch assignment
In the PROFI TX, all the switches can be installed and connected as needed. For
this reason, switched functions that are usually assigned to dip-switches or buttons
cannot be pre-set in the model templates. You have to configure these
assignments yourself according to the existing switches.
Using timers
The Frame, Sum, and Interval timers are only functional if a switch has been
assigned to them. The same control used for the Throttle control function is
assigned to the sum timer in all model templates. For this reason, this timer is
immediately functional. You activate the other timers by assigning a switch to them.
Control mixers (Ctrl.Mix)
The control mixers Ctrl.Mix are not initialised in the templates.

4.1.1BASIC model template
This model template is designed for simple power or glider-type models and for
models without aileron. On account of its simplicity this model template is ideally
suited to model flying simulators.
Servo assignment
If you install a second aileron servo to provide separate linkage for the ailerons,
simply assign the Aileron function to a free servo (see "Assignment" starting
from page 142). Would you like to raise the ailerons as an airbrake? In that case,
assign the AILERONS+ mixer to both aileron servos at the same position. In the
extended state, the airbrake will cause major load distribution changes: Change
the elevator to ELEVATOR+. It is then possible to compensate for the effects of
Throttle and Spoiler (airbrake).
Pre-defined mixers on the control side, with 2 more that can be defined by

4.3 Templates for land- or water-based models and tracked vehicles
4.3.1CAR / TRUCK model template
This model template is suitable for all types of vehicle models.
The control functions Support Legs, Ramp, Light, and Aux-1 to Aux-4 provide
the Slow function. This allows operating support legs and ramp at a realistically
slow speed. Smooth transition for Light is also possible.
Flight phase switching originates from model flying, as the names suggests. This
function has been left activated for vehicle models. Smart modellers will have good
ideas for practical application.
Control function assignments and names can be changed as required.
This template does not contain pre-defined mixers. To personalise control, 4 mixers on
the control side and 7 mixers on the servo side are provided, each with eight outputs.

4.3.3TRACKED V. model template
This model template is suitable for tracked vehicles.
Control function assignments and names can be changed as required.
Completed tracked vehicle models typically contain a functional building block that
combines "Throttle" and "Steering" for the two power systems.
If you are using 2 separate speed controllers, it is recommended to change the
servo assignment for Steering and Throttle to TRACK+ (page 142).
TRACK+ stands for a mixer that combines "Throttle" and "Steering". You configure
the required settings in the £ Mixer menu (page 126).
Set a small deadband value in the mixer for Steering. If "Steering" and "Throttle"
are assigned to the same stick unit, opening the throttle often involves a small
steering movement. Applying a deadband to "Steering" solves this problem.
To personalise control, 4 mixers on the control side and 6 mixers on the servo side
are provided, each with eight outputs.

5 Menus
The PROFI TX software is divided into status displays and menus that are
structured in several levels.
5.1 Status displays
Eight status displays provide information about transmitter, model and sensors.
The status display is shown after transmitter start-up or when exiting the main
menus.
Press the + or – buttons or use the central wheel to toggle between screens. Every
clockwise increment on the central wheel cycles to the next status display (see also
chapter 6 "Operating the transmitter" on page 160).
5.1.1Status display #1
Status display #1 provides an overview of the current battery and device status:
The device name is shown in the first line. You can overwrite this name with
customised text (menu: Setup > Transmitter > User data > Name
parameter, see section 5.3.8 "Transmitter" on page 109).
The left side of the table provides information about the battery, e.g. battery
voltage, remaining operating time (time to empty), etc.
The right side of the table provides information about the device, e.g. serial
number, uptime count, etc.

5.2 Menu structure
The PROFI TX menus are structured in several levels:
Main menus
The 6 main menus are opened via the 6 direct menu access buttons (see
section 6.1.1 "Direct access buttons for menus" on page 160).
The main menus only provide links leading to the menus themselves.
Each link is always indicated by a succeeding series of four full stops.
Menus
The menus can contain both links to sub-menus and parameters.
Sub-menus
The sub-menus only contain parameters.
Parameters
Parameters are set values which appear in menus and sub-menus. Some only
provide information, but others can be edited.
Uneditable parameters are skipped when browsing.
Navigation in the menus
You can use the buttons or the central wheel to navigate through the menus:
1. Press one of the direct access buttons to open the respective main menu.
2. Use the central wheel or press the + or – buttons to select a menu item.
3. Press the wheel or the ENTER button to access the respective sub-menu.
4. Press the wheel or the ENTER button to move to an input field.
Refer to chapter 6 "Operating the transmitter" on page 160 for detailed information
on how to navigate in menus and enter values.

Not all servos work properly with FastResponse. Incompatible servos may vibrate
excessively in idle position. Check your servo before starting off on the first flight.
FastResponse has a noticeable effect only on extremely agile models that are
equipped with fast servos.
5.3.1M-LINK
The radio link functions are set in the M-LINK menu.
Range check
When performing a range check, the transmitting power is significantly
reduced to allow shorter distances between transmitter and model (see section
3.6 "Range check" on page 47).
Set Failsafe
The current servo positions are stored in the receiver.
If Failsafe positions were stored in the receiver the servos return to these
positions after 0.5 seconds.
o Use the respective PROFI TX controls to move the servos
(surfaces) of your model to the desired positions.
o Set the value to ON. After a few moments, it reverts to OFF.
o Check the Failsafe function by switching the transmitter off.
FastResponse
FastResponse reduces the transmission cycle from 21 ms to 14 ms. This
reduces the response time for control commands. Only 12 servos can be
controlled when FastResponse is active.

Binding
Activates the binding procedure and displays the current binding status (see
section "Binding" on page 48).
5.3.2Flight phases
It is useful to have different settings and trims for specific flight phases when flying
models. The flight phases technology in the PROFI TX provides an easy and
convenient way to realize this. You can copy settings for one flight phase to another,
lock flight phases if they are not needed, assign switches to flight phases, etc.
Refer to section 8.2.10 "Working with flight phases" on page 207 for information on
how to work with flight phases, assign switches to flight phases, lock / unlock flight
phases, etc.
Flight phase number (1, 2, 3, or 4)
Identifies the flight phase in other menus. In the control function menus,
all settings that can differ between flight phases are accompanied by the
respective identifying number 1 to 4 for the flight phase.
Page 97
Menus
PROFI TX
Page 95
Flight phase name (e.g. SPEED1)
You can select the designations for the flight phases from a list of 13 pre-set
names (see section 8.2.10.5 "Changing flight phase names" on page 210).
After activating the input field for the name, select a suitable name by pressing
the + / – buttons or by using the central wheel.
Locked flight phases are shown crossed out.
x
Identifies the active flight phase.
Switch (e.g. 1>)
Switch that is assigned to the flight phase; the arrow indicates if the left (<) or
right (>) switch is associated.
Three dashes "---" indicate that no switch has been assigned for switching
between flight phases.
Slow
Transition time to the next flight phase.
Switching flight phases may involve major surface position changes. Sudden
major changes e.g. to camber-changing flaps or airbrakes make controlling the
model difficult and lead to undesired, hard transitions to the next flight phase.
These problems do not occur when the transition is performed slowly. The
transition is automatically calculated in such a way that all servos move to their
new positions in a synchronized manner and within the selected time frame.
The control commands by the pilot are not slowed down.
Possible range: 0.1 to 6.0 seconds
Pressing REV/CLR
Locks or unlocks the selected flight phase.

5.3.3Training (principle)
In trainer mode (teacher / student), a wireless connection is established between
two Multiplex transmitters via M-LINK.
The teacher transmitter controls the model and must be bound to the model
(Binding). The student transmitter transfers the stick signal to the teacher
transmitter via M-LINK. The teacher can transfer a freely definable group of control
signals to the student.
The teacher transmitter requires a receiving device for the student signal. On older
transmitters with DIN socket, the trainer stick is the receiving device; the PROFI TX
uses the COPILOT module.
The trainer stick or the COPILOT module are bound in the same way to the student
transmitter (Binding) as receivers.
5.3.3.1 Student mode
Set Training to ON. This activates the training system.
Set "Format" to MPX if the teacher uses an older Multiplex transmitter that
does not support the UNI format.
Set Mode to Student.
Now, the student transmitter must be bound to the receiving device of the
teacher transmitter. For this, "Binding" must be activated on both sides.
o Activate "Binding": The display changes to seeking...
o Now, activate "Binding" on the receiving device of the teacher
transmitter. Place the front of the PROFI TX close to the receiving
device of the teacher transmitter.
o After a few moments, the "Binding" display changes from
seeking.. to Teacher.
This indicates that the radio link to the receiving device of the teacher transmitter
has been established.

PROFI TX
Page 97
Both transmitters must use the same Format setting; otherwise, the centre positions
of the control signals will differ.
Remember to set "Training" to OFF if you wish to control the model directly.
The message STUDENT MODE flashes on the status displays #2 to #8 while the
Student mode is active.
5.3.3.2 Teacher mode
For Teacher mode, a COPILOT module and an assigned switch are required (see
section 3.7 "Trainer mode" on page 50).
Set "Training" to ON. This activates the training system. In Teacher mode,
the COPILOT module is switched on. This increases the power
consumption by 30 mA.
Choose the same servo format setting as on the student transmitter.
Otherwise, the neutral positions of the servos will not match.
Set the Mode menu item to Teacher. This switches the COPILOT module
on. The power consumption increases by 40 mA. Now, 7 control functions
are displayed below, which can be transferred to the student individually or
in groups.
Activate "Binding" on the student transmitter.
Open the "Binding" menu item and turn the wheel by one clockwise
increment. The display changes from OFF to seeking.. The COPILOT
module is now bound to the student transmitter. After a few seconds, the
display should change from seeking.. via OFF to Student. If this is not
the case, hold the PROFI TX over the aerial of the student transmitter (the
COPILOT is positioned below).
The following elevator example illustrates how control functions are
assigned to the student.
o Open the "Elevator" menu item.
o Operate the elevator stick on the student transmitter vigorously.
Page 100
Menus
Page 98
PROFI TX
Make sure that the model motor cannot start up!
Turn OFF the training system after completing the training. Otherwise, the student
may inadvertently re-establish the student connection by switching on the
transmitter and take control of your model.
Besides, the power consumption of the COPILOT module reduces the operating time.
o The servo channel used by the student transmitter for transmitting
the elevator signal is displayed next to Elevator, usually Ch2.
o Check on the model if the rotation direction of the student signal is
correct. You can reverse the direction by pressing the REV/CLR
button.
o Close the menu item.
Repeat these steps to assign all control functions that the student is
allowed to control.
If the teacher switch is switched on and the connection to the student
transmitter is established, the student controls the assigned control
functions.
Important information:
If the control functions are transferred to the student, the message
STUDENT CONTROLS flashes on the status displays #2 to #8.
If the connection to the student transmitter is lost, all control functions
are returned to the teacher.
Binding can be switched off by rotating the wheel to the left while the
menu item is open.
