To delete a paired camera, just re-pair the one you want to keep in stead of the one you want to delete (this will remove the unwanted camera).
Here is how to do it:
– In the menu, go to the camera setting.
– Choose the Camera you want to delete (for example Camera 2); it will start blinking.
– Then at the back of the Camera you want to keep (for example Camera 1) press and hold the “PAIR” button until the connection is established.
The above procedure will delete Camera’s 1 saved position and will move it to the position of Camera 2 (the one you wanted to delete). So now you will have only one camera paired.
