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.
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.
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.
2.2 Safety instructions for the transmitter battery
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.
2.3 ESD 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.
Safety instructions
PROFI TX
Page 17
Always follow the switching on/off sequence in order to avoid any uncontrolled,
dangerous start-up of the power system:
Switching on
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
2.4 Intended 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.
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.
Safety instructions
PROFI TX
Page 19
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.
MULTIPLEX Modellsport GmbH & Co.KG does not assume any liability for loss,
damage or costs which arise through the improper use and operation of our
products, or which are connected with such operation in any way.
As far as is legally permissible, the obligation to provide compensation for
damages, on whatever legal basis, is limited to the invoice amount of the quantity
of MULTIPLEX goods that were directly affected by whatever incident gave rise
to the damage. This does not apply if MULTIPLEX is obliged to accept unlimited
liability in accordance with mandatory law for deliberate or gross negligence.
Furthermore, MULTIPLEX Modellsport GmbH & Co.KG does not extend any
warranty for the completeness and correctness of the documents enclosed with the
radio control components.
