安全指导
Do not fly at night or in bad weather like rain or thunderstorm as this can cause erratic
operation or loss of control.
Make sure moving direction of all motors be same with the operating direction.
If not, please adjust direction first.
请不要在夜晚或者雷雨天使用此产品，因为恶劣的天气环境有可能导致遥控设备失控。
操控时，请先确认模型所有舵机的动作方向与操控方向一致。
如果不一致，请调整好正确的方向。
The shutdown sequence must be to first disconnect the receiver battery then to switch
off the transmitter, if the transmitter is switched off while the receiver is still powered, it
may lead to uncontrolled movement or engine start and may cause an accident.
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。
The 2.4G R/C system will affect the plane or the car nearby after you turn
on the transmitter.
特别要注意，如果附近有汽车正在运行或飞机正在飞行，开机后2.4 GHz RC系统可能会影
响到他们。

不要在户外雨天，有水的地方或当能见度有限的时候使用。
可能水分(水或雪)会进入到系统内部，不稳定的运行和失控可能发生。
Do not operate this R/C system when you are tired, not feeling well or under the influence
of alcohol or drugs.Your judgment is impaired and could result in a dangerous situation
that may cause serious injury to yourself as well as others.
当你感到疲倦，饮酒或吸毒后，不舒服的影响下，不要操作这个R / C系统。
判断力下降，而且可能发生危险的情况下，对自己或他人可能造成严重的伤害。
Do not operate in the following places:
Near other sites where other radio control activity may occur,
Near people or roads,
On any pond when passenger boats are present,
Near high tension power lines or communication broadcasting antennas,
Interference could cause loss of control,
Improper installation of your Radio Control System in your model could result in serious injury.
不要操作在以下的地方：
基站附近或其他无线电活跃的地方，人多的地方或道路附近，
有客船的水域，高压电线或通信广播天线附近，干扰可能导致失控，
安装不正确，无线电控制系统可能导致模型发生严重的伤害。
Do not touch the engine, motor, speed control or any part of the model that will generate
heat while the model is operating or immediately after its use.These parts may be very
hot and can cause serious burns.
当模型操作或使用后，请勿触摸发动机、电机、定速设定或任何可能发热的部分，
这些部分可能非常热，会造成严重的烧伤。
Please have an overall check about the model before any operation.
Any problem in radio control system or improper installation may cause out of control.
Simple distance test methods:
One hold the model, and the other one carry the transmitter to a proper place to check the
servo system condition.
Please stop operation if any exceptional case occurs.
Please check the model memory to make sure the matching is right.
总是在操作模型之前进行全面的检查。
无线电控制系统出现问题以及不正确安装，都有可能导致模型失控，
简单的距离测试方法：一个人把持模型另一个人持发射机走开，检查该伺服系统运转情况。
测试时要注意到若有异常出现，请不要操作模型。
也检查模型的记忆，以确保模型的匹配是适当的。
Do not operate outdoors on rainy days, run through puddles of water or use when
visibility is limited. Should any type of moisture (water or snow) enter any component
of the system, erratic operation and loss of control may occur.
Turn on the power, please check if the throttle neutral position is in its lowest position
while turning on the transmitter every time.When making adjustments to the model, do
so with the engine not running or the motor disconnected, you may unexpectedly lose
control and create a dangerous situation.
开机时，每次都要检查发射器的油门中位是否是最低。
当发射机作出调整时，可能模型的引擎没有运行或电机没有连接，可能会发生失控或意外事
故的情况。

DIGITAL PROPORTIONAL RADIO CONTROL SYSTEM
System Characteristic 系统特征
此系统采用高质量的增益天线，覆盖整个波段带宽。配合高灵敏度接收机，系统能有效的避免远距离传
播信号的干扰。
此系统使用低功率电子元件和高灵敏度接收机芯片。无线电频率模块采用间歇性信号传播，因此大大降
低了发射功率。比较而言，此系统功耗仅为FM版本的十分之一。
此系统采用信息回传功能，此功能更好的掌握当前模型的工作状态。从而增添了操控乐趣以及更加安全
控制模型。
This radio system works in the frequency range of 2.405 to 2.475GHz. This band has been divided into
142 independent channels. Each radio system uses 16 different channels and 160 different types of hopping
algorithm. By using various switch-on times, hopping scheme and channel frequencies, the system can
guarantee a jamming free radio transmission.
此系统工作频率范围是2.405到2.475GHz。整个波段被分为142个独立频点。每套遥控系统使用16个
不同频点和160种不同的跳频算法。通过开机时间不同，跳频规律不同和使用不同的频点，遥控系统能避免
干扰传播信号。
This radio system uses a high gain and high quality multi directional antenna. It covers the whole frequency
band. Associated with a high sensitivity receiver, this radio system guarantees a jamming free long range radio
transmission.
Each transmitter has a unique ID. When binding with a receiver, the receiver saves that unique ID and can
accepts only data from that unique transmitter. This avoids picking another transmitter signal and dramatically
increases interference immunity and safety.
每台发射机有一个唯一的ID码， 当和接收机对码之后， 接收机保存这个唯一的ID码并且只接受从这个ID码
发射机发出的信号。 这样可以避免接收到别的发射机信号，大大增强抗干扰能力和安全性。
This radio system uses low power electronic components and a very sensitive receiver chip. The RF
modulation uses intermittent signal transmission thus reducing even more power consumption. Comparatively,
this radio system uses only a tenth of the power of a standard FM system.
This system uses the two-way communication, which could control the working state of current model better
and make the operation more enjoyable and safer than before.

100%：输出量百分比率，值越小输出越小，反之越大（此调整量为0%到120%，工厂预设值为100%）。
:此图标表示当前你所设定调整的是哪一部分（分正负两部分，由方向盘及油门扣机来选定）。
操作方法:
在开机菜单下通过“确认”键进入菜单，通过“左右旋转”键进行EPA菜单选择，再按“确认”键进入此菜单的操作
（此时ST字符闪烁），然后通过“左右旋转”键进行通道ST到AUX通道的选择，选好要变更的通道后按“ＥＮＤ"键，
此时两个字符会闪烁，在此状态下通过方向盘及油门扣机进行单边选择（被选中的那边对应的图标 会进行切换），
然后按“左右旋转”键进行0-120%的设定，完成后按“ＥＮＤ”键可进入另一个通道的设定，依类推对三个通道进行
设定。
编辑完成后按“确认”键返回并进入菜单选择状态。
在任何状态下按“返回”键进入开机画面。

EPA
Function:
Use this function when performing left and right steering angle adjustments, throttle high side/brake
side amount adjustment, and channel 3 servos up side/down side operation amount adjustment
during linkage setup. Used to correct steering angle of adjusting left and right steering angles when
there is a difference in the left and right turning radios.
Parameter:
CHANNEL: channel number, from St to AUX
100%:output value. Adjustment range : 0~120% ( initial value is 100% )
: LEFT, FORWORD, or RIGHT, BACK ( select by steering wheel or throttle trigger )
Operation:
Press the "ENTER" button and turn to the “EPA” menu. Press the “ENTER” button to enter the “EPA”
menu. The selected channel will be blinking. Select the channel by turning the "ENTER" button, and
then press the "END" button (now the percentage will be blinking ). Select the icon by using the

此功能是对ST输出通道做输出变化量调整设定，此项设定同时对两部份（正半部负半部份)按同一比率进行设定,适应
不通机种及不同伺服器输出的要求,以达到最佳的操控效果.
参数说明:
CHANNEL 通道编号，通道ST
100%:输出量百分比率,值越小输出越小,反之越大(此调整量为0%到100%,工厂预设值;为100%),0%表示此通道没有输出,
100%表示全部输出,也就是最大输出.
操作方法：
在开机菜单下通过“确认”键进入菜单，通过“左右旋转”键进行D/R菜单选择，再按确认键进入此菜单的操作
（此时三个字符会闪烁），在此状态下通过按“左右旋转”键进行00%--100%设定调整，编辑完成后，按“确认”
键返回并进入菜单选择状态。

FAIL SAFE FUNCTION
E
621
Function:
Failsafe aims to prevent control loss during operation due to radio control signal loss between
transmitter and receiver. If the receiver is not able to receive any signal from the transmitter, the
throttle setting on the receiver will default back to its original setting.
Setting:
1. Turn on the transmitter.
2. Connect power on the r, the LED on the will turn solid.receive receiver
3. Adjust transmitter ’s throttle to the stop or break position, then keep still.
4. Press the “Setting” button on the receiver (shown on the picture above), the LED will start
flashing for 3 seconds and then stop, indicating the fail safe setting is completed.
Testing:
a. Turn on the transmitter.
b. Connect power on the receiver.
c. Turn off the transmitter:
d. The throttle servo will turn back to its original setting automatically.
失控保护功能说明
1.功能说明
失控保护功能是对模型车或船进行失控保护，避免因失控造成损失。主要是对油门通道进行控制，
当接收机收不到控制信号时，接收机的油门通道将会自运行到当初设定的值，以免误动作。
2.设定方法
1.将发射机开通电源进入工作状态。
2.将接收机接通电源进入工作状态，此时信号灯恒亮。
3.控制发射机的油门通道，使油门控制伺服器或调速器进入刹车或熄火状态，然后保持不动。
4.此时可看到油门通道的伺服器便会自动进入设定状态的位置。
3.测试
a.将发射机打开进入工作状态。
b.将接受机接通电源进入工作状态.
c.将发射机关闭电源。
d.此时可以看到油门通道的伺服器便会自动进入设定状态的位置。
