different mixes of treble, mid
and bass.

HD Radio™ Technology is the
digital evolution of analog
AM/FM radio. Your radio product
has a special receiver which
allows it to receive digital broad-
casts (where available) in addi-
tion to the analog broadcasts it
already receives. Digital broad-
casts have better sound quality
than analog broadcasts as digi-
tal broadcasts provide free,
crystal clear audio with no static
or distortion. For more informa-
tion, and a guide to available
radio stations and programming,
