此功能用于当接收机无法正常收到发射机的信号时，对应通道舵
机移动至预先设定的位置，保护模型和操作人员的安全。若发射
机未设置失控保护通道值输出，接收机在进入失控保护状态后
输出低电平；若发射机设置了失控保护，设置后各通道依照发
射机设置的参数输出。具体操作详见各发射机失控保护章节。
失控保护 Failsafe
This function is used to move the corresponding channel
steering gear to the preset position to protect the safety of
the model and operators when the receiver cannot normally
receive the signals from the transmitter.If fail-safe channel value
output is not set for the transmitter, the receiver outputs low
level after entering the fail-safe state; if fail-safe is set for the
transmitter, after setting, each channel will output according to
the parameters preset for the transmitter.Please refer to the fail-
safe section of each transmitter for operation details.
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 o 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.
车灯控制 Car lamp control
• Breathing mode: CH3 is in the neutral or rightmost position, and the left lamp, right lamp, headlamp and rear lamp are
in breathing-lamp ashing state;
• Sharp-ashing mode: CH3 is in the neutral or rightmost position, and the left lamp, right lamp, headlamp and rear lamp
are ashing quickly together.
3. Switching of car lamp modes:
• Power on the receiver to establish a connection. Turn the transmitter CH1 clockwise to the highest position and keep it
there, keep CH2 in the neutral position, and the receiver is switched to one mode every time it is powered on.
• The receiver is switched in four modes cyclically, the mode state before power-o is saved during power-o, and the
default mode is the normal mode;
• Forward and backward driving/braking are controlled by the CH2 channel value, and the forward and backward
directions can be switched in a control mode.
• Forward and backward directions are switched cyclically, and are saved in case of power failure. The default is forward
direction;
• Car lamp mode and forward/backward direction setting are allowed. The default state is restored when the receiver
nishes binding successfully.
Tips：
• CH1, CH2, CH3, and CH4 mentioned above are channels of the transmitter. Among them, CH4 mainly controls the
ashing of the emergency lamps;
• All the above operations are performed when the steering reversion switch for CH1/CH2 is not turned on. If the steering
reversion switch is turned on, the previous transmitter operation mode needs to be adjusted for the opposite direction.
• Steering CH1 and throttle CH2 can automatically identify the neutral position, that is, when the channel values of CH1
and CH2 are detected to be near the neutral position during power-on, the automatically detected channel value will be
regarded as the neutral value for controlling the car lamps.
