警告!
错误使用遥控设备将可能导致严重的伤害甚至死亡。
请在使用前完整阅读这本使用手册，并且在使用过程中
严格按照此手册的说明操作。
该
2.4G
无线电波段完全不同于之前所使用的低频无
线电波段。使用时要保持您的模型产品飞行在您的视线
范围内，因为大的障碍物将会阻断无线电频率信号从而
导致遥控失控和危险。
2.4G
无线电频率信号是沿直线传
播的，它不能绕过障碍物进行传播。在使用过程中，严
禁紧握发射机天线，否则将会大大减弱无线电传播信号
的质量和强度， 导致遥控设备失控和危险。
警告!
每次使用时，必须先打开发射机，然后再给接收机
通电。停止使用时，必须先断开接收机电源，然后再关
闭发射机。这样操作可以避免接收机接收到错误信号而
导致的伺服器无规律的抖动。这对于电动模型来说尤为
重要， 因为它有可能导致马达突然转动而致使人员伤亡。

The 2.4 GHz radio band has a completely different
behavior than previously used lower frequency bands.
Always keep your model in sight as a large object can
block the RF signal and lead to loss of control and create
a dangerous situation. The 2.4 GHz RF signal propagates
in a straight line and cannot circumvent objects in its
path. Never grip the antenna during operation as it sig
-nificantly degrades the signal and may cause loss of
control and damage to the system.
Always turn on the transmitter first then the receiver.
When turning off the system, always turn off there ceiver
first then the transmitter. This is to avoid having the
receiver on itself as it may pick a wrong signal and lead
to erratic servo movements. This is particularly important
for electric powered models as it may unexpectedly turn
on the motor and lead to injuries or death.
This
system is developed by the word's leading
manufacturer and has been tested for many years.
