Note: After binding procedure is completed, resupply the power and check if the receiver is truly
communicating with the transmitter.
1.1 For Taranis X9D/X9D Plus/X9E and Taranis Q X7/X7S, turn on the transmitter, go to the MENU – MODEL SETUP
– PAGE 2, choose External RF/Mode R9M/LBT (EU), and select BIND (OpenTX2.2.1 and its improved versions are
strongly recommended).
1.2 For Horus X12S/X10/X10S, turn on the transmitter, go to the RF SYSTEM, choose External RF (ON), and select
BIND under STATE.
2. Connect the battery to the receiver while holding the Bind button on the receiver. The RED LED on the receiver
will flash, indicating the binding process is completed.
3. Reboot the receiver and switch the RF module back to the normal mode. The flashing of the GREEN LED on the
receiver indicates the receiver is receiving commands from the transmitter.
B:In PPM mode
1. Select No Telemetry or Telemetry mode, then power on R9M while holding its F/S button, Green LED will be on
and Red LED will be flashing.
2. Connect the battery to the receiver while holding its Bind button. The Red LED on it will flash, indicating the binding
process in completed.
3. Reboot the R9M and the receiver. The flashing of the GREEN LED on the receiver indicates it is receiving commands
from the transmitter.

Binding Procedure
Binding is the process of uniquely associating a receiver to a transmitter RF module. A transmitter external RF module
can be bound to multiple receivers (not to be used simultaneously). A receiver can only be bound to one RF module.

Note:
1. The 2 modes both conform to the CE standard.
2. The receiver should be rebound after switching the modes between Telemetry (25mW) and No
Telemetry (500mW).
Instruction Manual for FrSky R9M ( EU ) Module
How to enable/disable the S.Port of R9M
-- For Taranis X9D/X9D Plus and Taranis Q X7/X7S, If you want to turn on the S.Port of R9M, turn off the Internal RF.
-- For Horus X12S/X10/X10S, turn on the transmitter. go to the RF SYSTEM, choose the External RF and select
the R9M, and select the S.Port or not.
More information please refer to the introduction manual for transmitter.
Note: If S.Port is disabled, communication related to S. Port between R9M and the transmitter will be
cut off.
• No Pulse: on loss of signal the receiver produces no pulses on any channel. To use this type, select it in the menu
and wait 9 seconds for the failsafe to take effect.
• Hold: the model will maintain the last position after the signal is lost. To use this type, select it in the menu and wait
9 seconds for the failsafe to take effect.
• Custom: the customized position of each individual channel. The model will move to the pre-set position after the
signal is lost. Move the cursor to “Set” and press ENTER, you will see FAILSAFE SETTING screen below. Move
the cursor to the channel you want to set failsafe on, and press ENTER. When moving the crresponding sticks or
switches, you will see the channel bar moving. Move the channel bar to the place you want for failsafe and long
press ENTER to finish the setting. Wait 9 seconds before the failsafe takes effect.
How to Set Failsafe mode (on the transmitter)
There are 3 failsafe modes: No Pulse, Hold, Custom
Note: If failsafe is not set, the model will hold the last position after signal is lost , thus it may fly away
or cause injury.
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. Under Range Check Mode,
the RF power would decrease and Range distance will reduce to 1/30--1/10 that of Normal Model.
1. Place the model at least 60cm (two feet) above non-metal contaminated ground (e.g on a wooden bench). The
receiver antenna should be in vertical position.
2. For Taranis X9D/X9D Plus/X9E and Taranis Q X7/X7S, turn on the transmitter and the receiver, go to: MODEL
SETUP/External RF/ Mode R9M/Range.
3. For Horus X12S/X10/X10S, turn on the transmitter and the receiver, go to: MDL/RF SYSTEM/External RF (ON)/
STATE (RANGE).
4. For PPM mode: Turn on the Switch1, power on R9M again.
