 12-251 Weatheradio« with Alert: How to Select a Broadcast Frequency

The first time you use your weatheradio, it is automatically set to use the NOAA weather broadcast frequency 162.400 MHz (Channel 1) and receive all SAME alert signals broadcast within a 50 mile radius of where you installed it. Depending on your location, you might need to select a different channel and enter one or two FIPS codes.


  • The weatheradio will not receive a weather alert while you are programming it.
  • FIPS Codes are six-digit numbers, indicating a particular state and county. Each digit must be entered individually and in sequence.
  • To stop programming the weatheradio at any time during the steps described in this section, set the Program/Operate switch back to Operate. The weatheradio exits program mode and saves any valid entries you have made.
  • The Program/Operate switch is located on the back of your weatheradio to the left of the Tone/Voice switch, as shown below.
