Resetting your Radio
You can reset many radio settings back to their factory defaults, this
• Erase any channels stored in memory
• Return to International channels, if another mode is selected
• Only For US version
• Return power settings to their original state
To perform the reset:

  1. Turn the radio OFF.
  2. Simultaneously press and hold the SCAN & DW buttons.
  3. While continuing to hold these keys, power the radio ON.
    The LCD remains blank for 2 seconds, and then the unit switches to
    channel 16.
