Use the 

 arrow keys of the left or right touch pad 

to move to the screen's "RF bind" line" then select the 
desired binding channel. For an example like that shown 
in the figure below, choose "BD2" because the binding 
channel designated as "BD1" in the screen's bottom line 
is already used by default for the receiver which was 
delivered with the set.

If not already off, now switch the receiver on. The red 
LED on the receiver will blink.
Press and hold the 

 button on the receiver while 

the LED continues to blink red for about 3 seconds then 
after about another 3 seconds begins to blink red/green. 
You can now release the 

 button As long as this 

LED blinks red/green, the receiver is in bind mode.
Now, within this 3 second period, start the so-called 
"receiver binding" process for the receiver to the 
currently active model memory by briefl y pressing the 
center 

 button of the right touch pad. At this time the 

screen's display will begin to indicate the duration of the 
"bond".

"Binding" multiple receivers per model
Multiple receivers per model can be bound if desired, 
whereby respective 

mx-20 HoTT programs offer the 

potential for managing a maximum of two receivers 
directly and for dividing up the 12 control channels (max) 
available on these two receivers as desired under menu 
control. Refer to additional details further down in this 
section. Binding two receivers is begun by fi rst binding 
the individual receivers as described below. 
In subsequent operation of the model only one of 
these receivers will establish a telemetry bond to 
the transmitter; the one which was activated in 
the "Tel. RCV" line of the "Telemetry" menu. For 
example:

Any telemetry sensors which may be built into the model 
should therefore be connected to this receiver because 
the transmitter only receives and evaluates data from 
the return channel of the receiver activated on this line. 
The second, and all other receivers, operate in parallel 
but are fully independent in slave mode.

Finding ...

If the receiver's LED, again blinking red, changes within 
about 10 seconds to continuous illumination in green, 
the binding process has been successfully completed. 
Your model-memory to receiver combination is now 
operationally ready. At this time the screen will now 
display "bind" (bound) instead of "n/a" (not attached). 
For example:

On the other hand, should the LED on the receiver 
blink red for longer than about 10 seconds, the binding 
process has failed. In this case the screen will continue 
to show the status as "n/a". If this should happen, try 
changing the position of antennas then repeat the entire 
procedure.

Binding other receivers
The binding channel you have chosen is already bound 
(as indicated by the "bind" status). with another binding 
channel. After initiating the RF bind process, instead 
of displaying "BINDING", the message shown below 
appears.
