A repeater after powering up joins an existing above ground Unet. This implies a
controller or bridge must already be present in the network for the repeater to be able
to join the network.
Once powered, a red LED on the front of the Repeater will aluminate followed by a series
of Green LEDs as the bridge searches the area for any existing hardware or networks. The
LEDs are very helpful in determining the current state and operation of the bridge.
