How does Manta M 1 UAV remotely control the frequency?

When leaving the factory, the remote controller and the aircraft have completed frequency matching and can be used after being powered on.

If you change the remote control, you need to re-adjust the frequency to use it. Perform frequency matching according to the following steps: 1) First, turn on the remote control and connect the mobile device. Then turn on the power of the smart flying battery and run DJIGOapp. 2) Select the "Camera" interface, click the icon of the remote controller, and then click the "Remote Controller Frequency Calibration" button. 3)DJIGOapp displays the countdown dialog box, at which time the status indicator of the remote controller displays blue light flashing and gives a "beep" prompt tone. 4) Press and release the frequency calibration key with a suitable tool to complete the frequency calibration. After the frequency matching is successful, the indicator light of the remote controller shows green light. The frequency key and frequency indicator light are located on the side of the aircraft.
