7.12 Fail-Safe
The receiver features a Fail-Safe function. If inter-
ference occurs, preventing the receiver picking up a
valid M-LINK signal, the servos move to the pre-
viously programmed positions. In the case of a model
aeroplane this usually means centred control sur-
faces, with the motor switched off. This significantly
enhances safety when flying a model.
Move the transmitter controls to the point where the
servos take up the desired fail-safe positions. When
you are satisfied, press the SET button on the re-
ceiver: This action per-
manently stores the Fail-
Safe positions in the re-
ceiver. However you can
overwrite the settings at
any time by setting new
positions and pressing the
button again.
7.13 Auxiliary (AUX) channel
The SMART SX features one switched channel (=
servo channel 6). This option can be used when an
M-LINK receiver with six or more channels is used.
The trim lever adjacent to the throttle stick controls the
switched function.

This function can be used to switch working systems
on and off, such as a model's lighting system, retrac-
table undercarriage, etc.
7.14 Range checking
Before launching a model you should always check
the range of the radio control system. Regular range
checks are very important - even when using a 2.4
GHz system - to ensure that the RC system continues
to work properly, and to allow you to detect problems
in good time.
To carry out a range check, switch the transmitter on,
then immediately press the multi-function button for a
SMART SX
period of two seconds, i.e.
until the Status LED glows
constantly. The transmitter
now emits an audible warning
signal every ten seconds to
alert you to the fact that it is in
range-check mode, and is
only transmitting at low power.
In this state the model control system must continue to
work up to a range of about fifty metres. If, and only if, this
is the case, the system will operate at full range - beyond
the limits of vision - when the transmitter is in normal oper-
ating mode. Switch the transmitter off to disable range
check mode; when you switch on again, the system will be
ready for normal use.
7.15 Model memory (ID)
The set is supplied complete with a
compact 2.4 GHz M-LINK receiver
with the UNI connector system,
whose small case and in-line servo
sockets make it ideal for use in rela-
tively small models. However, the
outstanding feature of this intelligent
receiver is its ID (model identification) capability.
This feature enables the SMART SX transmitter to recog-
nise your model, and switch to the corresponding model
memory. This eliminates the constant requirement to alter
servo directions and adjust trim settings, which is typical of
beginners' transmitters. If you possess several models
fitted with ID receivers, and switch to a different model, you
simply need to switch the transmitter off and then on again.
As soon as you hear the audible ID detect signal, your
model is ready to fly. The settings for compatible MULTI-
PLEX RTF and RR+ models are already programmed into
the transmitter when you purchase it, i.e. you do not have
to carry out any adjustments at all for these models.

6,
However, it is also possible to overwrite or fine-tune the
Mode 2 and 4
model data sets at the transmitter, which means that an ID
receiver can be used in any model.
Other M-LINK receivers (light or telemetry) can also be
operated in conjunction with the SMART SX transmitter. If
you use a non-ID receiver, the SMART SX remains at the
standard model memory "0" when it is switched on, and the
audible ID detect signal is disabled. Here again all adjust-
ment facilities are available, and the settings are stored
automatically and permanently.
All compatible MULTIPLEX ELAPOR® RTF and RR+ mod-
els are programmed into the transmitter at the factory. The
following receiver / IDs are available:
The receiver supplied in the set with the code 'ID 1' (# 5
5822) activates model memory 1 in the transmitter, to
which no model is assigned. This ID code is free, i.e. any
model can be operated with this receiver, and the user has
