The PS VR aim controller is a Bluetooth® device. You’ll need to pair your controller when you use it for the first time and when you use it with another PS4™ system.
With your PS4 system on, connect your controller using a micro USB cable*, then press the 2 (PS) button. Your controller pairs with the system and turns on. After you’ve paired your controller, you can disconnect the micro USB cable and use your controller wirelessly.
*The PS VR aim controller is not supplied with a micro-USB. Use the micro-USB cable for your DualShock 4 wireless controller.
If your controller won't pair (the light will flash if this is the problem), won't respond, or has input lag, please follow the instructions on how to reset the controller:
