5 Safety Notes
work correctly, it is therefore important to suppress the elec-
tric motors, and in electric-powered models it is essential that
every motor should be effectively suppressed. Suppressor
fi lters reliably eliminate such interference, and should always
be fi tted where possible.
Please read the notes and recommendations supplied by the
motor manufacturer.
Refer to the main
GRAUPNER FS catalogue or the Internet
website at www.graupner.de for more information on sup-
pressor fi lters.
Servo suppressor fi lter for extension leads
Order No. 1040
Servo suppressor fi lters are required if you are obliged to use
long servo extension leads, as they eliminate the danger of
de-tuning the receiver. The fi lter is connected directly to the
receiver input. In very diffi cult cases a second fi lter can be
used, positioned close to the servo.
Using electronic speed controllers
The basic rule is that the electronic speed controller must be
chosen to suit the size of the electric motor it is required to
control.
There is always a danger of overloading and possibly dam-
aging the speed controller, but you can avoid this by ensuring
that the controller’s current-handling capacity is at least half
the motor’s maximum stall current.
Particular care is called for if you are using a “hot” (i. e.
upgrade) motor, as any low-turn motor (small number of
turns on the winding) can draw many times its nominal cur-
rent when stalled, and the high current will then burn out the
speed controller.
Electrical ignition systems
Ignition systems for internal combustion engines can also
produce interference, which has an adverse effect on the
working of the radio control system.
Electrical ignition systems should always be powered by a
separate battery – not the receiver battery.
Be sure to use effectively suppressed spark plugs and plug
caps, and shielded ignition leads.
Keep the receiving system an adequate distance away from
the ignition system.
Static charges
Lightning causes magnetic shock waves which can interfere
with the operation of a radio control transmitter even if the
thunderstorm actually occurs several kilometres away. For
this reason …
… cease fl ying operations immediately if you notice an
electrical storm approaching. Static charges through the
transmitter aerial can be life-threatening!
Caution
In order to fulfi l the FCC RF radiation regulations appli- •
cable to mobile transmitting apparatus, the equipment’s
aerial must be at least 20 cm from any person when the
system is in use. We therefore do not recommend using
the equipment at a closer range than 20 cm.
Ensure that no other transmitter is closer than 20 cm from
•
your equipment, in order to avoid adverse effects on the
system’s electrical characteristics and radiation pattern.
Before you use the radio control system, the receiver
•
must be programmed correctly to suit the country in
which you are operating. This is essential in order to fulfi l
various FCC, ETSI and IC directives. Please refer to the
instructions provided with your receiver.
The receiver included with the system is set up at the fac-
tory for use in most European countries.
Never attempt to program the transmitter RF module
•
whilst you are operating a model. For the same reason
do not touch any of the programming buttons on the RF
module at such times.
Care and maintenance
Don’t use cleaning agents, petrol, water or other solvents to
clean your equipment. If the case, the aerial etc. gets dirty,
simply wipe the surfaces clean with a soft dry cloth.
Components and accessories
As manufacturers, the company of GRAUPNER GmbH &
Co. KG recommends the exclusive use of components and
accessories which have been tested by
GRAUPNER and ap-
proved for their capability, function and safety. If you observe
this rule,
GRAUPNER accepts responsibility for the product.
GRAUPNER cannot accept liability for non-approved
components or accessories made by other manufactur-
ers. It is not possible for
GRAUPNER to assess every
individual item manufactured by other companies, so
we are unable to state whether such parts can be used
without incurring a safety risk.
Liability exclusion / Compensation
We at GRAUPNER are unable to ensure that you observe
the operating instructions, and are not in a position to infl u-
ence the way you install, operate and maintain the radio
control system components. For this reason we are obliged
to refute all liability for loss, damage or costs which are in-
curred due to the incompetent or incorrect use and operation
of our products, or which are connected with such operation
in any way.
Unless otherwise prescribed by law, the obligation of the
GRAUPNER company to pay compensation is limited to the
invoice value of that quantity of GRAUPNER products which
was immediately and directly involved in the event in which
the damage occurred. This does not apply if
GRAUPNER is
found to be subject to unlimited liability according to binding
legal regulation on account of deliberate or gross negligence.
