DT-B90 Buzzer&LED Finder how to work?

1. DT-B90 Finder can power itself to beep and LED light to flash even the quad battery has been ejected.
2. Press the button for 2 or 3 seconds to turn on it before flying
3. You can use AUX4(SF Switch) channel to activate the Buzzer
4. You need to Press the button for 2 or 3 seconds to turn off it after disconnect the main battery.

Eachine M8N GPS rescue how to work?

1. Before Armed, GPS must search for more than 6 satellites to lock the home position.
2. After armed, observe the OSD data during the flight, and the rescue function can work normally only if the distance exceeds 100 meters. Otherwise, the quad will crash. If the remote controller suddenly loses signal, the GPS rescue function will work automatically and return to the home position, but the drone won't land automatically. You need to slightly control the stick to gain control of the drone when the remote control signal is restored and then control the drone to land.
3. In order to avoid mistake operation, we didn't enable Aux Channel to activate the GPS rescue function by default. You can set it by yourself from the mode tab of Betaflight configurator.
