How to Tune Into XM Channel 0
- 1). Press "Power" to turn on your XM satellite radio receiver. After a second, the station the receiver is currently tuned to will display onscreen.
- 2). Use the circular tuning dial or the "Previous" button (whichever application applies to your specific receiver) to tune backwards until the station indicator onscreen reads "0."
- 3). Wait a few seconds for your tuning selection to register. Your XM radio will scroll your unit's ID number across the screen.
