Using this Prolink cable is a breeze. Simply plug one end of the cable (the iDock connector) into your iPad, iPod, or iPhone. Then, plug the USB - A end into your computer's USB port or a power adapter. You can use it for charging your device or transferring data between your device and the computer. When it comes to maintenance, keep the cable away from sharp objects to avoid cuts and scratches. Don't bend the cable too sharply as it may damage the internal conductors. If the cable gets dirty, you can gently wipe it with a soft, dry cloth. And always unplug it carefully by holding the connector, not the cable itself. That way, you can ensure the cable lasts a long time and works well for all your charging and data - transfer needs.
