1.Button Functions
● BIND Button: Enter binding mode after radio transmitter is powered on.
● SETUP Button: Enter joystick calibration mode after radio transmitter is powered
on.
● Power Button: Turn the transmitter o/on.
There are three buttons on remote control radio transmitter.
2.Power On/O
POWER ON: Long press the power button on the transmitter for 3 seconds until it
beeps three times (do re mi) then release. The radio transmitter LED ring will ash
red quickly, then remain blue.
POWER OFF: A long press of the power button on the radio transmitter will turn it
o after three beeps (mi re do).
3.LED Indicator and Buzzer
The LED light indicates the working status of the radio transmitter.
Reason Solution
Red light solid on The throttle joystick or
switches are not in the lowest
Lower throttle and switches
to the lowest position.
Turn to blue then.
Red light ashing quickly
Blue light ashing slowly
Red light breathes slowly
Green light breathes slowly
The radio transmitter
is binding
Batte reaches the low
voltage limit
On charging
Charge complete
Charge the transmitter
Wait for completing binding
State of the LED Ring
The buzzer will alarm three times, which indicates a low batte and needs to be re-
charged.

4.Binding the Receiver
There are the steps to make the LiteRadio 2 SE enter binding status.
1. Power on the remote control radio transmitter󲞚and wait for its system to load
completely. LED ring is solid blue.
2. Press the bind button on the back of the transmitter to enter binding stutas. The
LED ring will be red and ash quickly.
3. The LED ring will change to solid blue 5 seconds later when transmitter exits
binding status. If not bind successfully, repeat the󲞚process󲞚above.
5.Switching Protocol
Note: switching protocol is only available for Frsky version radio transmitter.
ExpressLRS version or Bayang version are not suppoed.
The Frsky version could suppo 4 dierent protocols, including Frsky D16 FCC,
Frsky D16 LBT, Frsky D8 and Futaba S-FHSS. The protocol is indicated by the
ashing times of the red LED when power on, before the buzzer alarms.
LED Status Protocol Version
Flash once
Flash twice
Flash Three Times
Flash Four Times
Frsky D16 FCC (ACCST 1.X Version)
Frsky D16 LBT (ACCST 1.X Version)
Frsky D8
Futaba S-FHSS
1. Power the radio transmitter o;
To change protocols (Frsky FCC D16, Frsky D16 LBT, Frsky D8, or Futaba S-FHSS),
here are the steps:
2. Press and hold the BIND button while power the radio transmitter back on;

04
● The LED ring breathes in red means charging, while in green means fully charged.
● Turn o the radio transmitter.
● Plug in remote control radio transmitter with adapter by USB cable (5V output
adapter is allowed).
Remote control radio transmitter has a built-in 1000mAh batte. It indicates low
batte and needs to be re-charged if blue light ashes slowly. Below charging
method for reference:
The continue working time for full charged batte is about 8 hours.
6.Charging
Type-C Data Cable
3. Then the ash times of the red LED before buzzer alarms will change, according
to the tables above.󲞚
Note: LiteRadio 2 SE only work with D16 ACCST 1.X Frsky protocol. So if you use a Frsky receiver
with D16 ACCST 2.X version or ACCESS version, binding will fail.

7.HID Joystick
It is the safest and quickest method to get staed by using FPV simulator for
staers. LiteRadio 2 SE remote control radio transmitter suppos most of FPV
simulators on market with comprehensive conguration.
● Turn o radio transmitter.
Operation steps below:
● Install driver from PC automatically, prompt box pops up after successful
installation. Then, remote control radio transmitter works normally.
● Connect the transmitter to computer via USB data cable. Wait for the LED ring
breathes in red or green.
User needs to manually install driver if PC doesn't install automatically or installed
incorrectly.
DO NOT power on the transmitter rst and connect it to the PC. The USB po is invalid in this
situation.

8.Joystick Calibration
The joystick data may oset after it has used for a period of time (if joysticks is hit
by physical). User need to re-calibrate joysticks based on following steps:
● After powering on, press SETUP button on the back of remote control radio
transmitter, it hears two "Bee Bee" sounds, and red LED ash quickly (two ashes
each time), which means remote control radio transmitter entered calibration mode.
● Move throttle joystick and direction joystick to middle position, press SETUP
button again, wait until the buzzer beep three "Bee Bee Bee" sounds, red LED light
ashes quickly (two ashes each time), which indicates joystick data has been
acquired and enter into the bounda value calibration mode.
● Slowly rotate the throttle and direction joystick twice around the bounda of the
joysticks(counterclockwise/clockwise), then press SETUP button again, it hears a
long ''Bee'' sound about 3 seconds. And the red LED light stops ashing, indicating
that joystick calibration is complete successfully.

How to recognise if your radio transmitter suppos the BETAFPV Congurator?
Remove the cover on the back of the transmitter and there is a label, comes with "BETAFPV
Congurator Suppoed".
DO NOT power on the transmitter rst and connect it to the PC. The USB po is invalid in this
situation.
● Open the BETAFPV Congurator program in your computer and switch to the
congurator page for radio transmitter.
● Click the "Connect Radio Controller" button on the top right of the page.
● Connect the transmitter to computer via USB data cable. Wait for the LED ring
breathes in red or green.
How to enter the radio transmitter conguration page:

LiteRadio 2 SE遥控器是针对入门市场的一款模型遥控器。该遥控器从2020年发布以
来，成为深受广大模型爱好者喜欢的手柄遥控器之一。
LiteRadio 2 SE遥控器正面如下图所示。
2021年我们为LiteRadio 2 SE带来了更多的功能，更多的型号。
● 支持BETAFPV Congurator上位机调参和升级；
● 在原来的Frsky版本，Bayang版本的基础上，增加了支持ExpressLRS 2.4G协议版本。

1.按键功能介绍
●BIND键：遥控器开机状态，短按后遥控器进入对频模式。
●SETUP键：遥控器开机状态，短按后遥控器进入摇杆校准模式。
遥控器上有3个按键，其功能如下：
●开机键：长按开机/关机。
2.开机/关机
●关机状态下，长按遥控器电源键3秒，直至听到蜂鸣器发出三声响（do re mi），同时
红色LED灯亮起，然后变成蓝色常亮，遥控器开机成功。
●开机状态下，长按遥控器电源键3秒，直到听到蜂鸣器发出三声响（mi re do），同时
红色LED灯快速闪烁，遥控器关机成功。
3.LED提示灯和提示音
遥控器开关按键下有一颗RGB LED提示灯，用于提示遥控器的常见状态。
指示灯状态 状态说明 解决办法
红色常亮 开机时油门杆不在最低位 将油门杆拨到最低位
红灯快闪
红灯渐变闪烁
处于对频过程中
充电中
等待对频完成
蓝色慢闪
绿灯渐变闪烁
电池电压过低
充电完成
给遥控器充电
遥控器内置了一个蜂鸣器，当它连续重复报警三次时，说明电量过低，需要给遥控器充
电。

4.遥控器绑定接收机
在开机状态下，按下遥控器背面的BIND按键，遥控器将进入绑定状态，该过程为持续
5秒的红灯闪烁，待停止闪烁后，绑定过程结束。
1. 遥控器开机，确保LED灯环处于蓝色常亮；
2. 按一下遥控器背面的BIND按键，遥控器正面的电源按键灯会呈现红色闪烁，此时遥控
器进入时间为5秒的对频状态；
4. 5秒之后遥控器自动退出对频状态，检查遥控器是否对上接收机；如果没有，请重复
上面第二步操作。
3. 接收机进入对频状态，与遥控器对频；
5.遥控器协议查看与切换
关机状态下，按电源键开机，在BB响发出声音之前，可以看到红灯闪烁，闪烁次数代表
当前协议类型，具体如下：
注意：本章节只适用于Frsky协议遥控器。Bayang协议的遥控器，ExpressLRS协议遥控
器，协议不可以切换。
在关机状态下，先按住遥控器背面的BIND按键，同时按电源键开机，此时红色LED灯闪
烁次数将发生变化，红灯闪烁完毕协议即切换成功，其闪烁次数表示下次开机的协议版
本。
如何切换协议：
注意：LiteRadio 2 SE只能够支持D16 ACCST 1.X版本的协议。如果使用Frsky官方接收机，且该接收
机为D16 ACCST 2.X或者ACCESS协议，则无法对频连接使用。

6.低电量警报及充电
遥控器已经内置了1000mAh的电池，无需再外接电池。蓝灯慢闪烁，表示遥控器电池电
量较低，需要重新充电。充电方式如下：
● 关闭遥控器；
● 使用USB线连接遥控器和适配器（5V输出的适配器即可，例如手机充电器）；
● 红灯渐变闪烁，表示正在充电中；绿灯渐变闪烁，表示充电结束。
电池充满，可以连续使用8小时左右；
电池充满，关机放置，可以保证30天电池电量仍保持在80%左右。

7.HID Joystick模式使用
在连接个人电脑后，LiteRadio 2 SE遥控器可作为USB游戏手柄使用，可以用来练习
FPV模拟器。具体步骤如下：
Type-C数据线
● 遥控器关机；
● 使用一根USB数据线连接遥控器和PC电脑，遥控器LED变为红色或者绿色渐变闪烁；
● PC会自动安装驱动，驱动安装成功后弹出提示框，说明电脑已经成功识别到此遥控器
并可以正常使用。
若无法正常识别出遥控器，则可能是电脑没有自动安装驱动，或者识别了错误的驱动程
序，需要重新安装驱动。
注意：遥控器开机状态下连接到电脑，USB口无信号输出，无法使用Joystick功能。

8.摇杆校准
遥控器在使用一段时间之后，例如摇杆受到较重的物理撞击，可能会出现摇杆值发生偏
移的情况。这个时候可以通过校准摇杆值，确保其摇杆值处于中位。
● 在开机状态下，按一下遥控器背面的SETUP按键，待听到蜂鸣器持续的发出滴滴声
（2声），同时红色LED快速闪烁（每次闪烁两下），表示进入校准模式。
● 拨到摇杆，使其环绕摇杆边界缓慢转动两圈（逆时针/顺时针都可以），接着再次按
一下SETUP按键，再听到蜂鸣器发出一声长时间滴声（大概3秒），且红色LED灯停止
闪烁，表示摇杆校准完毕。
● 将两边的摇杆都移动至中间位置，再次按一下SETUP按键，待蜂鸣器持续发出滴滴滴
声（3声），同时红色LED灯快速闪烁（每次闪烁两下），表示摇杆中值已经校准完毕，
并进入边界值校准。

9.BETAFPV Congurator基本使用
BETAFPV Congurator可以用来对飞控或者遥控器进行参数配置，固件升级。
注意：遥控器开机状态下连接到电脑，USB口无信号输出，无法使用连接到Congurator。
如何判断手里的遥控器是否支持BETAFPV Congurator上位机调参？
● 取下遥控器后面的电池盖，可以看到有一张铭牌，上面写着BETAFPV Congurator Suppoed；
● 遥控器主板右上角有V2的丝印。
注意：老版本遥控器无法使用BETAFPV Congurator上位机调参。
