Congratulations on purchasing your new radio control 
system. We are delighted that you have selected the 
MULTIPLEX  SMART  SX  M-LINK.  You  are  now  the 
owner  of  a  superb  system  for  the  newcomer  to  the 
hobby  of  radio-controlled  modelling.  We  hope  you 
have  many  hours  of  fun  and  success  with  your  new 
equipment.

1.  Unpack the transmitter and receiver 
  Store the documents safely. 
 
2.  Insert the batteries 
It  is  essential  to  maintain  cor-
rect polarity  (see adjacent illus-
tration).  Reversed  polarity  may 
ruin the transmitter and / or the 
cells. 
 
3.  Binding 
•  Preparing the model 
When  binding  is  complete,  the  receiving  system 
immediately  starts  operating.  Secure  the  model 
carefully so that no damage can result if the propel-
ler should start turning. 
•  Prepare the transmitter 
Hold  the  multi-function 
button  pressed  in  and 
switch the  transmitter on, 
then  release  the  button 
again.  The  LED  flashes 
at a high rate. 
•  Prepare the receiver 
Switch  the  receiver  on 
with  the  SET  button  held 
pressed  in;  the  receiver 
LED  now  flashes  at  a 
high rate. 
 
If  binding  is  successful,  both  LEDs  revert  to  a  slow 
flashing rate. 
 
4.  Check the directions of servo rotation 
•  Model with ID receiver 
The transmitter emits an audible signal when it de-
tects  the  receiver.  No  further  adjustments  are  re-
quired. 
•  Model with normal M-Link receiver (light or teleme-
try) 
All  the  control  surfaces  (servos)  must  respond  to 
the  sticks  in  the  correct  direction;  check  and  re-
verse  the  servos  if  necessary:  move  the  correct 
stick  to  one  end-point  and  hold  the  multi-function 
button  pressed  in  for 
three  seconds:  the  ser-
vo  now  reverses,  and 
moves  to  the  opposite 
end-point. 
 
5.  Carry out a range check 
It is important to check radio 
range  before  the  first  flight: 
hold  the  multi-function  but-
ton  pressed  in  for  two  sec-
onds  immediately  after 
switching  on,  and  the  LED 
glows constantly. The transmitter now generates great-
ly reduced power, and emits an audible warning signal.
