What is Sirius Satellite Radio?  
Sirius is radio the way it was meant to be: up to 100 new channels  
of digital quality programming delivered to listeners coast to coast  
via satellite. That means 60 channels of completely commercial-free  
music. Plus up to 40 more channels of news, sports, and  
entertainment from names like CNBC, Discovery, SCI-FI Channel,  
A&E, House of Blues, NPR, Speedvision and Comedy World.  
NOTE  
When initially activating your subscription, if you have changed your  
subscription, or if SIRIUS itself has updated streaming broadcast  
service, automatic reselection of reception operates by following the  
current channel setting.  
At this time, audio reception may be momentarily interrupted.  
However, this interruption is not caused by radio interference or  
reception interference.  
Sirius is live, dynamic entertainment, completely focused on  
listeners. Every minute of every day of every week will be different.  
All 60 commercial-free music channels are created in-house and  
hosted by DJs who know and love the music. Do you like Reggae?  
How about Classic Rock or New Rock? Sirius has an array of choices  
spanning a vast range of musical tastes including the hits of the 50’s,  
60’s, 70’s, & 80’s as well as Jazz, Country, Blues, Pop, Rap, R&B,  
Bluegrass, Alternative, Classical, Heavy Metal, Dance and many  
others…  
From its state-of-the-art, digital broadcasting facility in Rockefeller  
Center, New York City, Sirius will deliver the broadest, deepest mix  
of radio entertainment from coast to coast.  
Sirius will bring you music and entertainment programming that is  
simply not available on traditional radio in any market across the  
country. It’s radio like you’ve never heard before.  
So Get Sirius and Listen Up! For more information, visit  
<www.sirius.com>.
