Connect the HRE-450 to the signal cables and ground wire:

1

Loosen the compression connector nuts on the bottom of the HRE-450 using one of the following methods:

Using your hand, turn the compression connector nuts counterclockwise.

If the compression connector nuts are too tight to loosen by hand, use groove-joint pliers to hold each 
cable fitting center locknut, then use groove-joint pliers to turn each compression nut counterclockwise.
