Safety Notes - GRAUPNER MX-10 HOTT Programming Manual

Safety Notes

Please read carefully!
We all want you to have many hours of pleasure in our
mutual hobby of modelling, and safety is an important
aspect of this. It is absolutely essential that you read
right through these instructions and take careful note
of all our safety recommendations. We also strongly
recommend that you register without delay at http://
www.graupner.de/en/service/product_registration, as
this ensures that you automatically receive the latest
information relating to your product by e-mail.
If you are a beginner to the world of radio-controlled
model aircraft, boats and cars, we strongly advise that
you seek out an experienced modeller in your fi eld, and
ask him or her for help and advice.
If you ever dispose of this transmitter, these instructions
must be passed on to the new owner.
Application
This radio control system may only be used for the
purpose for which the manufacturer intended it, i. e. for
operating radio-controlled models which do not carry hu-
mans. No other type of use is approved or permissible.
Safety notes
SAFETY IS NO ACCIDENT
and
RADIO-CONTROLLED MODELS
ARE NOT PLAYTHINGS
Even small models can cause serious personal injury
and damage to property if they are handled incompe-
tently, or if an accident occurs due to the fault of others.
Technical problems in electrical and mechanical sys-
tems can cause motors to rev up or burst into life unex-
pectedly, with the result that parts may fl y off at great
speed, causing considerable injury.
Short-circuits of all kinds must be avoided at all times.
Short-circuits can easily destroy parts of the radio con-
trol system, but even more dangerous is the acute risk
of fi re and explosion, depending on the circumstances
and the energy content of the batteries.
Aircraft and boat propellers, helicopter rotors, open
gearboxes and all other rotating parts which are driven
by a motor or engine represent a constant injury hazard.
Do not touch these items with any object or part of your
body. Remember that a propeller spinning at high speed
can easily slice off a fi nger! Ensure that no other object
can make contact with the driven components.
Never stand in the primary danger zone, i. e. in the rota-
tional plane of the propeller or other rotating parts, when
the motor is running or the drive battery is connected.
Please note that a glowplug engine or electric motor
could burst into life accidentally if the receiving system
is switched on when you are transmitting the transmitter.
To be on the safe side, disconnect the fueltank or the
fl ight battery.
Protect all electronic equipment from dust, dirt, damp,
and foreign bodies. Avoid subjecting the equipment
to vibration and excessive heat or cold. Radio control
equipment should only be used in "normal" ambient
temperatures, i. e. within the range -15°C to +55°C.
Avoid subjecting the equipment to shock and pressure.
Check the units at regular intervals for damage to cases
and leads. Do not re-use any item which is damaged
or has become wet, even after you have dried it out
thoroughly.
Use only those components and accessories which
we expressly recommend. Be sure to use only genuine
matching Graupner connectors of the same design with
contacts of the same material.
When deploying cables ensure that they are not under
strain, are not tightly bent (kinked) or broken. Avoid
sharp edges, as they can chafe through insulating
materials.
Before you use the system, check that all connectors
are pushed home fi rmly. When disconnecting compo-
nents, pull on the connectors themselves – not on the
wires.
It is not permissible to carry out any modifi cations to the
RC system components, as any such changes invalidate
both your operating licence and your insurance cover.
Installing the receiving system
In a model aircraft the receiver must be packed in soft
foam and stowed behind a stout bulkhead, and in a
model boat or car it should be protected effectively from
dust and spray.
The receiver must not make direct contact with the
fuselage, hull or chassis at any point, otherwise motor
vibration and landing shocks will be transmitted directly
to it. When installing the receiving system in a model
with a glowplug or petrol engine, be sure to install all
the components in well-protected positions, so that no
exhaust gas or oil residues can reach the units and
get inside them. This applies above all to the ON / OFF
switch, which is usually installed in the outer skin of the
model.
Secure the receiver in such a way that the aerial, servo
leads and switch harness are not under any strain. The
receiver aerial should be at least 5 cm away from all
large metal parts and any wiring which is not connected
directly to the receiver. This includes steel and carbon
fi bre components, servos, electric motors, fuel pumps,
cabling of all kinds, etc..
Ideally the receiver should be installed well away from
