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.

The receiver will cycle between D8, D16, and S-FHSS protocols.

• Three single flashes = D8 protocol.
• Three double flashes = D16 protocol.
• Three triple flashes = S-FHSS protocol.

1. When the flash pattern matches the transmitter protocol, press bind on the transmitter. The light will flash rapidly then return to solid.
2. 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.

Frequency Fine Tuning

Important Note: D8 and D16 protocol receivers must be frequency fine-tuned before use to eliminate frequency errors between the transmitter and receiver, ensuring optimal remote control distance and stability. Follow these steps:

1. Gradually lower the RF Freq. fine tune value until the receiver loses signal. Record this value (TUNE_MIN, typically negative).
2. Gradually raise the RF Freq. fine tune value until the connection is restored, then continue raising it until the radio loses the connection with the receiver again. Record this value (TUNE_MAX, typically positive).
3. Calculate the median between the two values using the formula: (TUNE_MIN + TUNE_MAX) / 2.
4. Set the RF Freq. fine tune to the calculated median value.

Example: If the connection is lost at -73 and regained at +35, the median is (-73 + 35) / 2 = -19. Once the Fine Tuning value is known, it can be used for all models using the same protocol.
