注 意 事 项
①海水具有很强的腐蚀性，此 AIO 不推荐用于海水环境，一旦落入海水中请立即使用淡水清洗。
②AIO 支持 3-6S 电池，切记不得将电池接反，否则会烧坏 AIO。
③收到产品后先进入 Betaflight 查看是否有检测陀螺仪和加速度计，以及陀螺仪姿态是否正常。
④在 Betaflight 中拉动油门，确保四个电机正常转动包括电机转向正确，再装桨试飞；拉油门时务必卸桨，以免发生重大
事故。
确认以上注意事项无任何产品问题即可装桨开始爽飞!

绿灯快闪
已进入对频模式
绿灯慢闪
无TX 模块信号连接
将AIO 接入电脑连接 Betafight，进
入接收机配置页面，在页面右下角点击
“接收机对频”，此时 AIO 的接收机绿
色指示灯会从慢闪变成快闪，代表已进入
接收机对频模式。
注意：对频成功后接收机指示灯会由
快闪变为慢闪，表示对频成功，稍等片刻
指示灯会变为常亮，代表连接成功，对频
成功后接收机会记住对频信息，以后重启
会自动连接，无需重新对频；
Betafight 4.3 固件仅支持
ELRS_V2.x 版本高频头。

CAUTIONS
①Seawater is highly corrosive, it is not recommended for use in
seawater. Please wash with fresh water immediately and then dry it once
drone touched seawater.
②Support 3-6S battery, remember not to plug the battery positive and
negative interface in reverse, otherwise it will burn out.
③After receiving the AIO, first connect to computer on Betaflight software
to check whether the gyroscope and accelerometer are detected, and
whether the gyroscope attitude is normal.
④Increase the throttle in Betaflight software to ensure the normal rotation
and correct rotation direction of the 4 motors, and then install the propellers
for a test flight; be sure to remove the propellers when pulling the throttle in
Betaflight software to avoid accidents.
After confirming the above precautions without any problems, you can
install the propellers and start flying!
RC LED Status
Receiver Mode
Green Light Stays On
Paired
Green Light Fast Flashing
In Pairing Mode
Green Light Slow Flashing
Not Paired
Connect to computer by USB-C cable, open
the Betafight software and click “connect” button,
enter the receiver configure page, and click "Bind
Receiver" button. At the same time, the green
receiver led indicator (I.E. “RC LED”) will change
from slow flashing to fast flashing, indicating that
the receiver has entered pairing mode.
Reminder: after the pairing is successful, the
led indicator will change from fast flashing to slow
flashing, indicating that the pairing is successful,
after a while, the indicator light will turn steady on,
indicating that the connection is successful. After
1st pairing, the receiver will remember the pairing
info. In the future, every time the drone is powered
on, it will automatically connect & no need to rebind.
Betaflight 4.3 firmware only supports
ELRS_V2.x TX Module.
