Quick Start Guide
To break a pairing you need to hold the mode button in for more than 10 seconds, less than 15. As detailed in the quick start guide.
After a pairing is broken, to re-pair units you simply need to tap the mode button on both the transmitter and receiver, the "Link" light will start flashing rapidly and the units should repair after a couple of seconds.
Resetting the IP config, which will put the unit back into a DHCP mode and make it discoverable by AIM is a little more complicated. You need to first remove power from the unit, then re-power it and as quickly as you can press the mode button and hold it for between 5 and 10 seconds. Then power cycle the unit. There won’t be any sort of confirmation flash when doing this. It's often easiest to do this reset while the unit is disconnected from the network.
