8.4 HOLD and FAIL-SAFE
If no signal is picked up, or if the received data are corrupt, the
last valid information is passed on to the servos in order to
bridge the loss of signal (HOLD mode).
If interference should occur with FAIL-SAFE invoked, the servos
... run to a previously defined position at the end of the HOLD
period (0.75 second).
FAIL-SAFE is switched OFF in the receiver's default state, and
after a RESET. FAIL-SAFE is activated when the FAIL-SAFE
settings are initially set up using the SET button on the receiver.
!
Note: if you are using a COCKPIT SX M-LINK or ROYALevo
/ pro / M-LINK transmitter, it is also possible to set the FAIL-
SAFE values directly from the transmitter.
If you wish to disable FAIL-SAFE again, the receiver must be
reset to the default state (RESET
must repeat the binding procedure (
!
Note: always activate FAIL-SAFE!
For safety reasons we recommend that you always activate
FAIL-SAFE, and ensure that the FAIL-SAFE settings you select
will cause the model to take up as safe an attitude as possible
(e.g. motor OFF, control surfaces neutral, ...).
Selecting the FAIL-SAFE settings:
Use your transmitter to move all the servos (and the speed con-
troller) to your preferred FAIL-SAFE positions. Press the SET
button briefly (0.5 to 1 second). The servo settings are now
stored, and the LED flashes the confirmation signal (LED code 5
8.1).
After sixteen seconds in FAIL-SAFE mode the receiver stops
feeding signals to the servos. Analogue servos and some digital
servos (see instructions) then become "soft", in order to prevent
the danger of stalled servos. Modern speed controllers switch
themselves off, but a few digital servos remain "hard", and main-
tain their last position.
FAIL-SAFE terminates as soon as the receiver picks up valid
signals again.
Testing the FAIL-SAFE settings:
Move the sticks to positions other than the FAIL-SAFE settings,
and then switch the transmitter OFF: the servos should go into
HOLD mode briefly (0.75 seconds), and then move to the FAIL-
SAFE positions which you previously selected.
It is absolutely essential to check and update the FAIL-SAFE
positions when necessary, e.g. when installing the receiver in a
.
new model
!
Checking the FAIL-SAFE function:
The receiver can be operated with the transmitter switched off,
but only for testing the FAIL-SAFE function. Caution: if the FAIL-
SAFE settings are incorrect, the motor could start running: injury
hazard!

8.5 RESET to factory default settings

It is possible to reset the receiver to the factory default settings.
If you do this, all the data you have entered, such as binding
information, FAIL-SAFE settings ... are lost permanently.
Hold the SET button pressed in for at least ten seconds (as a
guide, the LED goes out when you press the button, comes on
again after two seconds, then off again after ten seconds).
When the RESET is complete, the LED displays the confirmation
signal (LED code 5 8.1).
9. SMART ID
RX-4/9 or 4/16 FLEXX M-LINK ID
At regular intervals the
receiver sends an identification signal (SMART ID) back to the
RC system transmitter. If you are using a transmitter which sup-

ports the SMART ID function (e.g. SMART SX or SMART SX
FLEXX), the transmitter automatically loads the correct settings
for the model.
There are fifty IDs. By default the
LINK ID
is set to ID 8. If you use several of these receivers,
you can set them to different IDs; to do this you require the
MULTIPLEX Launcher PC software (available as a download
from http://www.multiplex-rc.de) and the MULTIPLEX USB lead
# 8 5149 (not included in the set).
To change the SMART ID, connect the USB lead to the receiver
socket marked B/D and your PC, and switch the receiver on.
The remainder of the procedure is described in the Help section
of the MULTIPLEX Launcher PC program.

NSTALLATION
• Protect your receiver from vibration, especially in models
powered by an internal-combustion engine (e.g. pack it loosely
in foam).
• Locate the receiver at least 150 mm from electric motors,
petrol engine ignition systems, any other electronic com-
ponents such as speed controllers for electric motors, and
drive batteries. Keep the aerial away from these components.
• Install the receiver in the model in such a way that the aerial
is as far away as possible from all conductive materials.
• If your model's fuselage consists of conductive materials (e.g.
carbon fibre), then the aerial must be installed in such a way
that the active part of the aerial (the final 30 mm) is located
outside the model.
• Do not shorten or extend the receiver aerial or the aerial feed
cable. If you need a longer or shorter aerial feed cable,
please contact the MULTIPLEX Service Department or an
authorised MULTIPLEX service centre.
• Do not deploy the aerial parallel to servo leads, high-current
cables or electrically conductive parts (e.g. pushrods).
• Do not deploy the receiver aerial inside or in contact with
model components which are laminated or reinforced with
electrically conductive materials (metal foil, carbon fibre,
metallic paints etc.), as they have a shielding effect.
• High-current cables, e.g. those attached to the speed con-
troller, motor and flight battery, should be kept as short as
possible.
• Reception quality can be optimised by fitting a special ferrite
ring (# 8 5146) or suppressor filter lead (# 8 5057) in the speed
controller cable. It is also advisable to fit effective suppressors
to conventional (brushed) electric motors (not brushless types)
(e.g. use the suppressor set # 8 5020).

ANGE HECKING
Regular range checks are very important - even when using a
2.4 GHz system - in order to ensure reliable operation of the
radio control system, and to enable you to detect sources of
interference in good time. This applies in particular:
• Before the use of new or changed components, or existing
components in a new or modified arrangement.
• Before re-using radio control system components which were
previously involved in a crash or a hard landing.
• If you have encountered problems on a previous flight.
Important:
• Always ask a second person to help you with your range
check, so that one of you can secure and observe the model.
