The first step would be connect the remote to the drone by putting both on the same radio channel. Most of the time it is 1, 2, 3 and other times they can be much more advanced as to avoid being hacked, such as military drones. Once you have paired the devices, place the drone on a safe flat surface and I recommend standing at least 10 feet away.
Now push slightly on the left throttle stick to make sure all four propellers are moving. This tells us that all motors are working properly. Do this without lifting the drone much. You should also look out for instructions that come with your specific drone as these step-by-step instructions are just the basics for flying drones.
