Range Check
A pre-flight range check should be done before each flying session. Reflections from nearby metal fences,
concrete buildings or tress 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. X8R supports 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.

Binding Procedure
Binding is the process of uniquely associating a particular receiver to a transmitter module. A transmitter module
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 module (please refer to the module instruction
manual for switch positions). Release the button. The RED LED on the XJT module will flash, indicating the
transmitter is ready to bind to the receiver.
2. Set X8R receiver in bind mode
(see below chart for details)
, The RED LED on the receiver 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. The receiver/transmitter module binding will not have to be repeated,
unless one of the two is replaced.
What’s New!
More number of channels: 1~8ch from conventional channel outputs, 1~16ch from SBUS port,
or combine two X8R to become a 16 channels receiver.

PORT
Smart Port (S. Port) is a signal wire full duplex digital transmission interface developed by FrSky
Electronic Co., Ltd. All products enabled with Smart Port (including XJT module, X8R receiver,
new hub-less sensors, new Smart Dashboard,etc), serial port user data and other user input/ output devices
can be connected without limitations for numbers or sequences at a high transmission speed.
