1.5 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.
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).
Introduction
Page 14
PROFI TX
Moisture may impair the function of the transmitter and other components of the
radio control system.
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" on page 9).
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.

1.6 Safety instructions for the transmitter battery
The transmitter battery powers the 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: They 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 1.12 "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, avoid deep
discharge, and do not charge with reversed polarity. Observe of the permissible
temperature range for the battery.
Mishandling the battery incurs the risk of combustion, explosion, chemical burns and
fire.
Introduction

PROFI TX
1.7 ESD notes for electronic sub-assemblies
The sub-assemblies of radio control transmitters (main circuit board, modules) 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 subassembly is touched.
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.

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. Do
not use the radio control to regularly limit servo travels. Preferable: Adjust
control surface levers and pushrods mechanically and as thoroughly as
possible. Avoid lost motion (sloppy linkages). Use configuration options on
the servo side of the RC transmitter only for fine-tuning.
Observe the above-mentioned guidelines to make full use of the resolution
(positioning accuracy) of your radio control system.
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.
Keep servo cables as short as possible.
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 40Ncm torque you can estimate the required battery capacity using
the following formula:
Capacity [mAh] ≥ number of servos 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 control surfaces and linkages.
Stability and flawless condition of pushrods, 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 batteries and periodic checks of the
voltage curve and capacity, employing a charge process and battery charger
suitable for the type of battery in use.
Pre-flight checks
Charge the transmitter, receiver and power system batteries carefully to full
capacity, and verify their state of charge at regular intervals.
Ensure that the correct model memory is active on the transmitter.
Carry out a range check (see section 2.6 "Range check" on page 46).
Check the function and effect of all primary and secondary control systems.
If you discover any irregularities, do not fly. Locate the problem, eliminate it, and
then check again.
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.

1.9 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.
Observe also the advice included in the relevant transmitter documentation!
