1. Press and hold the
receiver BIND button [5] while powering on the receiver ,release the BIND button after receiver is powered on or
powering on the receiver first, press and hold the BIND button 3 seconds , the LED [7] 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.
对码
Binding
发射机在更新完后，如无法与接收机对码，需强制更新接
收机。
1. 接收机按下对码按键，上电十秒钟后指示灯三闪一灭，
或者先给接收机上电，长按对码键 10 秒后指示灯三闪
一灭，松开对码按键；
2. 在发射机端选择接收机更新并进入更新状态；
3. 更新完成指示灯慢闪。
强制更新
Forced update
失控保护功能用于在接收机失去信号不受控制后，接收
机按设置好的失控保护值进行通道输出以保护模型及人
员安全。
• 本款接收机共支持三种失控保护模式 :" 无输出 "、
" 保持 "、" 固定值 ";“无输出”模式指在进入失控
保护状态后 PWM、PPM、i-Bus out、 i-Bus 2 转换
器保持无输出信号通道值，S.BUS、i-Bus2、i-bus
转换器输出最后收到发射机的信号通道值,“保持”
模式指在进入失控保护状态后，保持输出最后收到
发射机的信号通道值；“固定值”模式指在进入失
控保护状态后，保持设置的信号通道值进行输出信
号。

兼容性
Compatibility
该接收机兼容所有 AFHDS3 的发射机。（注：目前适用于PL18 1.0.55、
NB4 2.0.93 和 NB4 lite 1.0.10 及之后的版本固件使用的高频库为 3.0
版本的发射机。）
注意事项：
• 使用前必须确保本产品与模型安装正确，否则可能导致模型发生严重损坏。
• 关闭时，请务必先关闭接收机电源，然后关闭发射机。如果关闭发射机电源时接收机仍然在工作，将有可能导致遥控设备失控或者
引擎继续工作而引发事故。
• 确保接收机安装在远离电机，电子调速器或电子噪声过多的区域。
• 接收机天线需远离导电材料，例如金属棒和碳物质。为了避免影响正常工作，请确保接收机天线和导电材料之间至少有 1 厘米以上
的距离。
• 准备过程中，请勿连接接收机电源，避免造成不必要的损失。
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 may lead to unintended
operation or loss of control.
• 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.
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 [5] for then
approximately ten seconds until the LED [7] flashes three times,Or power on
the receiver first, press and hold the BIND button for 10 seconds, and then the
LED [7] 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.
The failsafe function is used to output the channel 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.
• This receiver supports three failsafe modes: "Free", "Hold", and "Fixed
value"; "Free" mode refers to PWM, PPM, i-Bus out, i-Bus 2 converter
entering the failsafe state keep the channel value of no output signal. The
S.BUS, i-Bus2, and i-bus converters output the last received signal channel
value of the transmitter. "Hold" mode means that after entering the failsafe
state, keep the output of the last transmitter signal;the "Fixed value" mode
means that after entering the out-of-control protection state, the set signal
channel value is maintained to output the signal.
The FGr4B receiver is compatible with all AFHDS 3 transmitters (Note:
It is currently applicable to PL18 1.0.55, NB4 2.0.93 and NB4 lite 1.0.10
and later versions. The high-frequency library used by the firmware is
version 3.0.)
