re: radio installation

["Giller,Bruce C." <bgiller@domain.elided>]

	Some radios require both switched and unswitched power sources (two
separate wires).  The switched power is to run the
radio/tape/CD/DVD/plasma screen.  The unswitched is to run the memory
portion of the unit so that it won't forget the stations you've saved.
