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.

Press the X button to navigate to the Settings screen.
Press the down arrow to the Calibrate Controller option and select it by pressing the Check button.
Step 4: Move the Joysticks.
Step 5: Verify and save the Calibration.
NOTE: When the Check button is pressed to save the calibration, the Brain will make a cheer sound.
