Static discharge protection of electronic sub-
assemblies
The sub-assemblies of a radio control sys-
tem transmitter (main circuit board, RF
module, Channel-Check, scanner) are fitted
with components
statically sensitive. They can be destroyed,
or their useful life shortened, if an electro-static dis-
charge takes place when the sub-assembly is touched.
Be sure to take the following protective measures when
handling electro-statically sensitive sub-assemblies:
"Earth" yourself before touching or working on such
assemblies by making electrical contact with your en-
vironment (e.g. touch an earthed radiator).
Open the base unit (if necessary) and touch a large
area of it, to create potential balance relative to the
base unit.
Do not take the sub-assembly out of its conductive,
statically shielded bag until you have earthed your-
self. Avoid touching the electronic components or
soldered joints directly. Hold the sub-assembly only
by the edges of the circuit board.
If you have to store a sub-assembly outside the base
unit, keep it in the protective conductive bag in which
the module was supplied. Never allow the module to
contact a conventional (non-protective) foam, styro-
foam or other plastic material directly.

Range checking

Range checking is a method of testing the RC system
which gives extremely reliable information about the
operating condition of your radio control system.
We have concocted a range-check recipe which will al-
ways leave you on the safe side. It is based on our own
experience and measurements.
1. Move the aerial to an upright,
angled position and collapse
the segments completely
(push them together) (
9.5.2.).
2. Set up the model with the tip
of the receiver aerial about
1m above the ground.
3. Ensure that there are no large
metallic objects (e.g. cars,
wire fences etc.) in the vicin-
ity of the model.
4. Do not carry out the check if
there is any other transmitter
switched on - even on a dif-
ferent channel.
5. The range check will not
work properly in mountainous regions.
6. Switch on the transmitter and receiver. At a range
of about 80m between transmitter and receiver
check that the control surfaces respond accurately
to the stick movements, and do not carry out any
uncontrolled movements. Close to the range limit
the servo output arms may move from their nomi-
nal position by up to the width of the arm (servo jit-
ter).
7. Secure the model and repeat the check with the
motor running (varying the throttle setting from
idle to full-speed).
which are electro-

The stated range of 80m is only a general guideline. Ac-
tual range varies widely according to environmental
conditions. For example, in mountainous terrain or in
the vicinity of powerful radio transmitters, radar stations
or similar installations, effective range may only be half
that stated.
If radio range is restricted, what can you do to locate
the cause of the problem?
1. Change the position of the receiver aerial.
Metal or carbon fibre reinforced parts close by will
adversely affect reception conditions.
The effect of electric power systems and ignition
systems also alters if you change the position of the
aerial.
2. Disconnect the servos from the receiver one by one,
repeating the range check each time.
Over-long cables without suppressor filters have an
adverse effect on reception conditions. Servos also
deteriorate with age, and generate greater interfer-
ence than when new (brush sparking, motor sup-
pressor capacitors vibrated loose, general wear etc).
If you cannot effect an improvement by simple
means, try removing the complete system and op-
erating it outside the model. This allows you to
check whether the fault is in the system, or in the
installation in the model.

4. Liability / compensation

As manufacturers, we at MULTIPLEX Modellsport GmbH
& Co. KG are not in a position to ensure that you ob-
serve the operating instructions, the conditions and
methods of installing, using, operating and maintaining
the radio control system and its components. For this
reason MULTIPLEX Modellsport GmbH & Co. KG deny all
liability for loss, damages or costs which are incurred as
a result of the incorrect use and operation of the
equipment, or are connected with such use in any way.
Unless otherwise prescribed by binding law, the obliga-
tion of MULTIPLEX Modellsport GmbH & Co. KG to pay
compensation, regardless of the legal argument em-
ployed, is limited to the invoice value of that quantity of
products manufactured by MULTIPLEX Modellsport
GmbH & Co. KG which were immediately and directly
involved in the event which caused the damage. This
does not apply if MULTIPLEX Modellsport GmbH & Co.
KG is deemed to be subject to unlimited liability accord-
ing to binding legal regulation on account of deliberate
or gross negligence.
