Step 1: Tether the Controller.

Connect one end of the Tether Cable to the powered-off VEX IQ Robot Brain with a charged VEX IQ Robot Battery and the other end to the Controller.

Listen for the “click” when the Tether Cable is inserted into the Controller and Brain to confirm that the Tether Cable is attached securely.

Step 2: Turn on the Brain.

Verify that the Controller is connected by noticing the connected icon on the top right of the screen next to the battery life icon.

Step 3: Go to Settings: Calibrate Controller.

Step 4: Move the Joysticks.

Brain screen is shown in the Calibrate Menu. Two icons represent the controller's joysticks. Below, a message reads Move both joysticks in a full circle.

Move both joysticks in a full circle. When finished, press any button on the Brain or the Controller.

Step 5: Verify and save the Calibration.

Brain screen is shown in the Calibrate Menu. The two joystick icons are centered to indicate that the controller calibration is complete. At the bottom of the screen, icons indicate that the Check button can be used to Save and the X button can be used to Cancel.

Press the Check button to save the calibration or press the X button to cancel and return to the Settings menu.
