How do I sync the WPB3000 with my current PWR500 network?

Press the Security button on the bottom of the PWR500 for two seconds and release.  You should notice the Power light begin to blink.  Then press the Security button on the WPB3000 for two seconds.  The Power light on the WPB3000 should begin blinking and within a few seconds the Link light on both units should link up.
