Bind Method

1. Turn on your transmitter and select the desired protocol.
2. Enter bind mode on the receiver. Press and hold the bind button while powering on the receiver.
3. The receiver will cycle between D8, D16, and S-FHSS protocols.
4. Three single flashes= D8 protocol.
5. Three double flashes= D16 protocol.
6. Three triple flashes= S-FHSS protocol.
7. When the flash pattern matches the transmitter protocol, press bind on the transmitter. The light will flash rapidly then return to solid.
8. Cycle the power to the receiver after binding.

Fail-safe Protection

1. Press the BIND button once within 10 seconds of the receiver being powered on, and the receiver will save all the current channel values of the remote control as the fail-safe value.
2. 10 seconds after the receiver is powered on, the BIND button function will be disabled to prevent accidental changes to the fail-safe settings while preparing the model for flight.

D8 and D16 compatible receivers MUST be frequency fine-tuned before the flight.
Once the radio is bound to the receiver:
Return to the RF Freq. fine-tune option

1. Lower the value until the radio loses the connection with the receiver. Record the value (TUNE_MIN).
2. Raise the value so that the connection is restored, then continue to raise it until the radio loses the connection with the receiver again. Record the value (TUNE_MAX).
3. Calculate the median between the two values (TUNE_MIN + TUNE_MAX) / 2 = TUNE_MEDIAN
4. Set RF Freq. fine-tune to the median value

Example
Connection is lost at -73 and +35; the median is -19: Once the Fine Tuning value is known, it can be used for all models which use the same protocol. For more information visit:
