How to Bind the T12D Transmitter with the EWRF Long-range Module and Receiver

1. Install the RF module onto the T12D transmitter. Power on both the T12D and the receiver (connect the receiver to the flight controller’s TELEM port, then power on the flight controller).
2. On the T12D transmitter, go to Menu → Receiver Settings → RF Protocol, and set Module Select to External.
3. Select the protocol and baud rate corresponding to your RF module (refer to your module’s manual for details). For an ATA ELRS RF module, select ELRS as the protocol and use the default 400K baud rate. Then enter Parameter Settings.
4. Wait for the transmitter to read the RF module parameters.

Note: If the RF module and receiver are unbound, no signal icon will appear in the upper-right corner of the transmitter.

1. Bind the receiver: Power the receiver off and on three times consecutively to enter binding mode (the receiver LED will double-flash).
2. On the transmitter’s current screen, select Bind → BEGIN (default is CANCEL) to start binding.
3. Binding successful: A signal icon will appear in the upper-right corner of the transmitter, and the RF receiver LED will stay solid on.
4. If binding fails: Repeat steps 5 and 6.
