4. Binding 1. Press and hold the receiver BIND button [11] while powering on the receiver, release the BIND button after receiver is powered on, the LED [12] on the receiver will flash rapidly;

2. Put the transmitter into bind mode;

3. The binding process is complete when the LED on the receiver stops flashing and is on continuously. If a transmitter that has had its radio frequency (RF Standard) set to AFHDS3 1 way (please refer to your transmitter user manual) enters bind mode, the receiver LED will instead flash slowly. Exit bind mode on the transmitter and if the receiver LED stops flashing and is on continuously, the binding process is complete. 4. Check to make sure the transmitter and receiver functions are working correctly, repeat steps 1 to 3 (binding process) if any problems arise. Forced update 1. 2. 3. If after a firmware update is performed and the transmitter is unable to bind to the receiver, the receiver may need to be put into forced update times. 1. Power on the receiver while pressing the BIND button [11] for then approximately ten seconds until the LED [12] flashes three times,release the BIND button. 2. Go to the RX Setup menu on your transmitter and select RX Update. 3. When the receiver LED flashes slowly, the update is successful. Failsafe 1. This function protects your vehicle by preventing unexpected behaviors in case of signal lost. 1. Users should always input Fail Safe parameters before operating their vehicles. If the Fail Safe function has not been set on the transmitter and signal lost occurs, the receiver will continue to operate and maintain all output value at the last received instructions from the transmitter. If the Fail Safe parameters on the transmitter has set been set, the receiver will set output values according to user parameters during signal lost. Compatibility NB4 Lite FRM302 AFHDS3 PL18NB4 The FGr8B receiver is compatible with all AFHDS 3 transmitters and RF modules (including PL18, NB4, NB4 Lite, FRM302 etc.) 1 Attention:

AFHDS 3 FBr8 PL18 V1.0.55 PL18EV V1.0.28 NB4 V2.0.93 NB4 Pro V1.0.1 FBr8 The receiver supports two -way binding and one-way binding, and can be set at the transmitter side. The transmitter will display the information returned from the receiver after the two-way binding is completed. Follow the steps below to bind in two-way binding:

1. Select [2 WAY] for RF standard of the transmitter, then put the transmitter into binding mode. 2. Connect the BVD interface signal pin to the CH5 channel signal pin with the binding cable and power on the receiver. The receiver enters the binding state and the receiver LED flashes fast. 3. When the LED of the receiver is solid on, the binding process should be finished. The transmitter exits the binding mode automaticlly. 4. Remove the binding cable from the receiver. 5. Check to make sure the transmitter and receiver functions are working correctly, repeat steps 1 to 4 (binding process) if any problems arise. Follow the steps below to bind in one-way binding:

1. Select [1 WAY] for RF standard of the transmitter, then put the transmitter in binding mode. 2. Put the receiver into binding mode ( Refer to the description above for entering binding mode). 3. After the receiver LED becomes slow flashing, then put the transmitter to exit the binding state. At this time, the receiver LED is solid on indicating the binding is successful. 4. Remove the binding cable from the receiver. 5. Check to make sure the transmitter and receiver functions are working correctly, repeat steps 1 to 4(binding process) if any problems arise. Note: If a transmitter with AFHDS 3 protocol cannot be bound with a FBr8 receiver, check whether their RF library versions are consistent. Transmitters of PL18 V1.0.55 or later, PL18EV V1.0.28 or later, NB4 V2.0.93 or later, and NB4 Pro V1.0.1 or later can be directly bound with a FBr8 receiver. Firmware Update FlySkyAssistant 3.0 www.flysky-

cn.com LED LED CH1 CH3 The firmware of this receiver can be updated via the FlyskyAssistant (Only version 3.0 or later is supported. The firmware of FlyskyAssistant is available on the Flysky official website). This receiver can be updated through the following two modes:

Mode After the binding between the transmitter and the receiver (the LED of the receiver is solid on), connect the transmitter to the computer, then open the FlyskyAssistant in the computer to update the firmware. FBr8 Receiverhttp://www.flysky-cn.comCopyright 2023 Flysky Technology Co., Ltd. Firmware Update Mode : Connect the transmitter to the computer. Then put the receiver to enter the forced update mode by referring to the following way(The receiver LED works in three-flash-one-off mode repeatedly in forced update mode). Afterwards, open the FlyskyAssistant in the computer to update the firmware (When the forced update is finished, the state of receiver LED will change to slow flash from three-flash-one-off). To enter the forced update mode: Firstly, connect the binding cable to the signnal pins of the CH1 interface and CH3 interface. Sencondly, power on the receiver. Then the receiver will enter the forced update state. Failsafe

[ ]PWM ;

1. PPM/i-BUS/S.BUS/i-BUS2 [ ] [ ]

2. S.BUS/i-BUS2 3. PPM/i-BUS [ ] [ ]

The failsafe function is used to output the channel value according to the out-of-control protection value set by the user after the receiver loses its signal and is out-of-control to protect the model and personnel. It can also be set failsafe for each channel respectively. This receiver supports three failsafe modes: No output, Hold, and Fixed value. No output No output for PWM interface. Hold Keeps the last output value. Fixed value Outputs the failsafe values set for each channel. Notes:

1. For bus signal types such as PPM/i-BUS/S.BUS/i-BUS2, a single or several of these channels are not allowed to be in No output mode. The actual signal is held at the last output value when the channel is set to No output mode. 2. Because the S.BUS/i-BUS2 signal information contains failsafe flag bits, the failsafe settings of each channel are communicated to subsequent devices by the failsafe flag bits. If the connected devices support the failsafe flag bit analysis, the failsafe values set for each channel are output after out of control. 3. For the signal PPM/i-BUS without failsafe flag bits, it supports the setting of the signal to No output mode in case of out of control. After setting to No output mode, regardless of the setting of the failsafe of each channel, each channel will be in No output mode after out of control. 1 Attention:

Make sure the product is installed and calibrated correctly, failure to do so may result in serious injury. Make sure the receiver's battery is disconnected before turning off the transmitter, failure to do so lead to lose control. Unreasonable setting of the Failsafe may cause accidents. Make sure the receiver is mounted away from motors, electronic speed controllers or any device that emits excessive electrical noise. Keep the receiver's antenna at least 1cm away from conductive materials such as carbon or metal. Do not power on the receiver during the setup process to prevent loss of control.
