Binding Procedure
Binding is the process of uniquely ass ociatin g a particul ar recei ver to a trans mitter mod ule. A trans mitter mod ule
can be bound to multiple receivers (not to be used simultaneously). A receiver can only be bound to one
transmitter module.
Follow the steps below to finish the binding procedure:
1. Turn on the transmitter while holding the F/S button on the XJT module (set to LR12 mode, Switch 1 is OFF
while Switch 2 is ON). Release the button. The RED LED on the XJT module w ill flash, indicati ng the t ransmitter i s
ready to bind to the receiver.
2. Connect the battery to the receiver while holding the F/S button on the rec eiver. T he RE D LED on the r eceiv er
will flash, indicating the binding process is completed.
3. Turn off both the transmitter and the receiver.
4. Turn on the transmitter and connect the battery.
The GREEN LED on the receiver indicates the receiver is receiving commands from the transmitter.
Range Check
A pre-flight range check should be done before each flying session. Reflections from nearby metal fences,
concrete buildings or trees can cause loss of signal both during range check and during the flight. Follow the steps
below to perform the range check.
1. Place the model at least 60cm (two feet) above non-metal contaminated ground (e.g. on a wooden bench).
2. The receiver antennas should be separated in the model, and do not touch the ground.
3. The module antenna should be in a vertical position.
4. Turn on the transmitter and the receiver, press the F/S button on the XJT module for 4 seconds to enter range
check mode, the RED LED will be off, GREEN LED will flash rapidly. The effective distance will be decreased to
1/30 (at least 30m).
5. Walk away from the model while simultaneously operating the controls on the transmitter to confirm all
controls’ normal operation.
6. Press the F/S button on the XJT module for 1~2 seconds to exit range check mode, RED LED will be back on,
indicating normal operation is back.
Failsafe
Failsafe is a useful feature in which all controls move to a preset position whenever the control signal is lost for a
period of time. L9R receiver is support failsafe function for all channels. Follow the steps below to set failsafe
positions for each channel:
1. Bind the receiver first and turn on both the transmitter and the receiver;
2. Move the controls to the desired failsafe position for all channels;
3. Press briefly the F/S button on the receiver (less than 1 second). The Green LED will flash twice, indicating
the failsafe position has been set in the receiver.
To disable the failsafe function, re-bind the receiver.

Failsafe is recommended to set when system is firstly used, or receiver has been re-bound. Follow steps below
to set failsafe.
Option-1: How to set failsafe to a user-determined state on lost signal:
1) Bind the receiver to the transmitter module first and turn on both the transmitter and the receiver;
2) Move the controls to desired failsafe position for all channels;
3) Press briefly the F/S button on the receiver and you are done.
Option-2: How to set failsafe for no pulses on lost signal:
1) Turn off the transmitter, power on the receiver, and then press briefly the F/S button on the receiver.
Note:
If failsafe is not set, failsafe default will hold last position before signal is lost. In this case, there
exists risk that your model will fly away or cause injury.
L9R Receiver is not support failsafe setting on Taranis X9D transmitter.
Note: After binding procedure is completed, recycle the power and check if the receiver is really
under control by linked transmitter.
The receiver/transmitter module binding will not have to be repeated, unless one of the two is
replaced
