SMART SX instructions # 985 5335 (LA 06.04.2020) • Errors and omissions excepted •
MULTIPLEX
switched channel can also be used, controlled by
the throttle function trim lever.
• All the primary control surface functions feature
digital trims.
• A buzzer is used to provide audible feedback to
the user, indicating the most important processes,
such as: detecting the ID receiver, range-check,
voltage monitor, trim function, Dual Rate setting,
model select.
• The transmitter software is carefully structured
with ultra-simple operation in mind. The simplicity
of operating the transmitter makes it extremely
easy to set it up to suit virtually any other model
from a huge range of manufacturers. The trans-
mitter even stores the final trim settings for each
specific model.
• The pioneering, ultra-secure M-LINK transmission
process with its intelligent channel management
system creates the best possible pre-conditions
for totally reliable operation. The M-LINK process
makes it possible to operate up to 150 models
simultaneously without mutual interference.
• With the three recommended AA-size dry cells
the SMART SX transmitter operates for the enor-
mously long time of up to 25 hours. The unit also
includes an integral voltage monitor with a war-
ning threshold set at a sensible level.
• It is possible to set up the transmitter to control al-
most any RC model currently available.
• The SMART SX transmitter is ideal for use as a
Pupil transmitter in a Trainer system, providing
the beginner with the perfect opportunity to learn
the initial steps in the art of model flying quickly
and safely. The wireless connection to the
Teacher transmitter requires the M-LINK Trainer
Stick - which can be used with any Trainer-
capable MPX transmitter fitted with a multi-
function socket - or a PROFI Tx using COPILOT.
• The transmitter software (= firmware) can be up-
dated using the integral interface located in the
battery compartment. This makes it possible to
keep the transmitter completely up-to-date at all
times. The same method can be used to transfer
the settings for new RR+ models into the transmit-
ter.
4. SAFETY NOTES, OTHER INFORMATION
Radio-controlled models and the associated RC sys-
tems are not playthings in the usual sense of the term.
Building and operating them safely calls for a certain
level of technical competence and manual skill, to-
gether with discipline and a responsible attitude at the
flying field. Errors and negligence in building and fly-
ing the model can result in serious personal injury and
damage to property. Since neither we, as manufactur-
er, nor the retailer have any control over the construc-
tion, maintenance and operation of our products, we
are obliged to take this opportunity to point out these
hazards and to
emphasise your personal responsibility. We
deny all liability.
It really is essential to observe the following safety notes,
as you bear the responsibility for the safe operation of this
product:
• Please read right through these instructions, and do not
operate the system until you have studied the infor-
mation and the following safety notes.
• It is never permissible to make technical modifications
to the radio control system. Use genuine accessories
and replacement parts exclusively; these include trans-
mitter battery, receiver and servos.
• If you intend to operate the system in conjunction with
products from other manufacturers, you must ensure
that they are of good quality and work properly. Every
new or changed combination of components must be
checked exhaustively before use; the equipment must
work correctly and at full range. Do not operate the RC
system or the model if something is not in order. First
seek out and eliminate the problem.
• A model flying out of control for whatever reason can
certainly cause serious personal injury and property
damage. For this reason it is the modeller’s responsibil-
ity to take out third-party insurance for model aircraft,
and heed the regulations. This really is mandatory.
• Always keep to the correct sequence when switching
the system on and off, as this avoids the risk of the mo-
tor bursting into life unexpectedly:
- When switching on
Always switch the transmitter on before connecting
the flight battery or switching the receiving system on.
- When switching off
Always disconnect the flight battery or switch the re-
ceiving system off before switching the transmitter
off.
• Have your RC system - especially the transmitter and
receiver - checked at regular intervals (every two or
three years) by an authorised MULTIPLEX Service
Centre.
• The transmitter must be operated exclusively within the
stated temperature range. Please note that condensa-
tion may occur inside the transmitter if it is subjected to
a major change in temperature. Damp can affect the
operation of the transmitter and any other electronic
equipment.
• If moisture affects any electrical unit, cease operations
immediately, disconnect the power supply, and allow
the device to dry out completely, preferably with the
case open; this may take several days. After this carry
out a careful check of its functions. If you are still un-
sure, take the affected equipment to an authorised
MULTIPLEX Service Centre for checking.
In addition to these safety notes, please observe the follow-
ing points.
• Build your model with great care; this applies in particu-
lar if you have to repair your model. The responsibility
for completing the work competently rests with you.
• Install the servos and mechanical linkages in such a
way that the control surfaces deflect freely, and are not
