Before connecting and calibrating the RC, make sure that:
* There is no battery connected to the drone.
* The propellers are not mounted.
## Connecting the RC transmitter
1. Open the *Vehicle Setup* tab and select the *Radio* menu.
2. Power on the transmitter by sliding the **POWER** slider up.
3. Make sure the transmitter-receiver link is working.
The transmitter LCD screen should display the connection:

The LED on the receiver should glow steadily. Read the [radio troubleshooting article](radioerrors.md) if the link does not work.
## Transmitter calibration
1. Press the *Calibrate* button.
2. Set the *Throttle*, *Yaw*, *Pitch*, and *Roll* trims to 0
* Trims are small constant offsets applied to a control in order to make your drone fly correctly.
* Move the trimming slider to the center using trimming buttons until you hear a long beep. Do this for each axis.
3. Press *OK* in QGroundControl.
