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.
Receiver

protocols.
3. When the flash pattern matches the transmitter protocol,
press BIND on the transmitter. The light will flash rapidly
then return to solid.
4. After binding, cycle the power to the receiver.
*Does not support frsky transmitter, only for MPM radio.
RSSI OUTPUT
This receiver has a total of 6 PWM channels + 9 SBUS Channels
(Sbus has 8 control channels + 1 RSSI channel). Channels 1-8 are
controlled by the remote controller, the 9
strength RSSI value output by the receiver, which can be read by
various flight controllers and sent to the OSD to display signal
strength in the FPV video feed.

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 to the
fail-safe settings while preparing the model for flight.
*Note: D8 and D16 compatible receivers MUST be frequency
fine tuned prior to flight.
Once the radio is bound to the receiver:
Go to the RF Freq. fine tune option in Model Setup.
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
that use the same protocol.
