Fei Teng wireless technology (FT-RF) is one of the first pioneers in manufacturing the RF antenna field in Taiwan. Since our foundation in 2001, we have been constantly innovating and developing with a determination to understand and promptly respond to our customers' needs.
对频步骤：
1. 当接收机连接到飞控以后，通过连接USB给飞控供电。第一次插入USB后，当看到接收机上的LED灯熄灭马上断开USB。重复操作一次，当第三次插入USB后LED会开始双闪，这意味着接收机进入对频模式。
2. 将ES24TX模块或者DIY 2. ELRS高频头模块和遥控器正确连接后，拷贝ELRS.LUA 文件到遥控器里的SD卡上，目录是SD Card/Scripts/tools, 然后运行ELRS.LUA进行Bind操作。
3. 绑定成功后，接收机上的LED会变为常亮，同时也能接收到遥测信号。
4. 接收机LED状态含义：
PP接收机:常亮对频成功或者连接通讯正常，LED双闪正在对频，LED慢闪接收不到发射机信号
EP1/EP2接收机：常亮对频成功或者连接通讯正常，LED双闪正在对频，LED慢闪接收不到发射机信号，LED快闪通讯模式此时可以通过电脑或者手机连接更新程序
