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.
When you use R9M / R9M Lite,
A: In R9M mode

1. Put the transmitter RF module into binding mode

1.1 For Taranis Series transmitters, turn on the transmitter, go to MENU - MODEL SETUP - PAGE 2, choose External RF
Mode R9M LBT (EU) or FCC, and select BIND ( OpenTX 2.2.2 and its improved versions are strongly recommended).

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.The binding of the receiver/transmitter moudle will not have
to be repeated, unless one of the two is replaced.

1. Choose the needed working mode by Switch 1 and Switch 2 on R9M, 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. The binding of the receiver/R9M will not have to be repeated unless one of the two is replaced.

Note: After binding procedure is completed, resupply the power and check if the receiver is truly communicating
with the transmitter.
R9M Lite has no PPM mode.
More information please check R9M / R9M Lite manuals.

• 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
