线双向传输，它的设计小巧，便于安装。可输出标准 PPM 信号
PWM 信号和 i-BUS 信号。
The FGr4S uses AFHDS 3 (Third Generation Automatic Frequency
Hopping Digital System). It uses a internal single antenna with two-
way transmission capabilities and is designed to be compact and
easy to install. It can output standard PPM,PWM and i-BUS.
产品介绍 Introduction
接收机概览 Receiver overview
CH 1- CH 4：连接舵机、电源或其他各部件。
i-BUS：扩展通道。
BIND：连接对码线。
CH 1 - CH 4: Connects the servos, power supply or
other components.
i-BUS: for channel expansion.
BIND: For bind cable.
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.
对码 Binding
1. 将对码线插入 BIND 接口；
2. 将电源线插入其他任意接口，接收机指示灯快闪表示进入对码
状态；
3. 将发射机进入对码状态；（发射机进入对码状态的方式可能不
同，请根据发射机的使用说明书进行操作）
4. 当接收机指示灯变为慢闪时，将对码线和电源线从接收机上取
下；
如果发射机是双向，则接收机指示灯无慢闪状态。
5. 将电源线重新连接至接收机，接收机指示灯常亮表示对码成功；
6. 检查发射机、接收机、模型是否正常工作。如需重新对码，请
重复以上步骤重新对码。
1. Insert the bind cable into the receivers BIND port;
2. Plug the power cable into any other port, and the the
receiver's LED will start to ash indicating that it has entered
bind mode.
3. Put the transmitter into bind mode; (See the transmitter's
instruction manual for more information)
4. Binding is successful when the receiver's LED starts to ash
slowly. Remove the power and bind cables from the receiver.
If the transmitter is bidirectional the reciever status indicator
will not fash slowly.
5. Reconnect the power cable to the receiver.
6. Check to make sure that the transmitter and receiver are
working as expected, if there are any issues or unexpected
operation follow the steps above to bind again.

为确保信号强度，建议安装接收机时保持接收机天线向上并且
远离金属。
To ensure good signal strength, make sure the receiver
antenna is as far away from any metal parts when installing
the receiver.
