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.
A: In R9M mode
1. Put the transmitter RF module into binding mode
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) or FCC, and select BIND (OpenTX2.2.1 and its improved versions are
strongly recommended).
