Bind Method

1. On the receiver, presses and hold the BIND button and power on the receiver at the same time. The receiver LED red and green lights will be on at the same time, the receiver is now ready to bind.
2. The multi-protocol RF of the remote control select the D16 protocol, presses the [BIND] option, the red light of the receiver will flash indicating successful bind.
3. Exit [BIND] mode on your radio then power off and power on again the receiver. At this time, the green light of the receiver is always on, this indicates the bind process was a success.

The remote control opens the mode menu when binding. SBUS always outputs channels 1-16
Ch1-8 Telem ON: The receiver’s PWM interface outputs 1-8 channel signals, and telemetry is turned on
Ch1-8 Telem OFF: The receiver’s PWM interface outputs signals from channels 1-8, and telemetry is turned off
Ch9-16 Telem ON: Receiver PWM interface outputs 9-16 channel signals, and telemetry is on
Ch1-16 Telem OFF: The receiver PWM interface outputs 9-16 channel signals, and telemetry turned off

Setting Fail-safe

The receiver supports a variety of fail-safe protection methods, you can select the corresponding settings in the remote-control Failsafe mode to customize the fail-safe protection

Failsafe mode Failsafe setting option description

1. Not set: If the runaway protection is not set, the remote control will pop up a corresponding prompt to remind you to set the runaway protection.
2. Hold: Failsafe hold, keep the channel output at the last moment before losing signal.
3. No pulses: no pulse, when the receiver is out signal range, the output signal of all channels will be shut down
4. Receiver: On the receiver short press the BIND button for less than 1 second, the receiver LED green light flashes twice, this will save the current channel values and stick positions of the remote control as the receiver failsafe values.
5. Custom: Select [Set] to enter the following interface, you can define each channel value in this interface, select the lowest Channels=>Failsafe option, you can send the current settings to the receiver as the receiver’s failsafe values.

Battery Telemetry

1. The R168 has built in voltage telemetry for your main flight battery or any battery up to 18v. Connect the positive electrode of the battery to the BATT interface to so the telemetry sensor can take a voltage reading.
   Note the ground circuit must be on the same circuit as the battery being read.

2. Please follow the below diagram. Please DO NOT connect the BATT sensor to a battery greater than 18v or the receiver will be damaged.

To enable the telemetry function on your radio, navigate to the telemetry page and select “Discover New Sensors” to scan for sensors currently on the receiver.

Ensure you calibrate the voltage of the sensor. Select the RxBt option and follow the popup menu. Adjust the ratio parameter until the displayed voltage matches the actual voltage of the battery being read by the receiver.

RF Freq.fine tune = (-73+35)÷2
RF Freq.fine tune = (-38)÷2
RF Freq.fine tune = 19

D8 and D16 compatible receivers MUST be frequency fine tuned before 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.
