(USA only)
SIRIUS satellite radio provides 100 chan-
nels of digital-quality radio, among others 
music, sports, news, and entertainment, 
free of commercials. SIRIUS satellite radio 
uses a fleet of high-power satellites to 
broadcast 24 hours per day, coast to 
coast, in the contiguous U.S.
This diverse, satellite-delivered program-
ming is available for a monthly subscrip-
tion fee.
For more information and service 
availability call the SIRIUS Service 
Center (
page 216), or contact 
www.siriusradio.com.
iIf no weather band station is received 
after three consecutive scans of the 
complete frequency range, then the 
scan stops at the channel with which it 
began and 
NO WB FOUND
 appears in the 
display.
If this happens, switch back to 
standard radio mode.
