1.) Turn on Bluetooth on your computer and your phone.
2.) On your phone, choose Start'Applications'Bluetooth'BT PC Remote.
3.) Press Add
4.) On your computer, right-click the Bluetooth icon and from the menu select Bluetooth Setup Wizard.
5.) Check that you know the service you want and you want to find a Bluetooth device that provides that service. Click Next.
6.) Select Human Interface Device and click Next.
7.) When your computer sees the MotoQ, select it and click Next.
8.) Enter a passkey code if prompted and press Accept.

A key map will appear on your phone to guide in using it as a remote. This is a great way to step away from your computer during a PowerPoint presentation or to sit back and enjoy streaming video without hunching over the machine each time you want to issue a command.
