The radio will re-set itself at the next weekly test, or the next watch/warning issuance.

If the radio goes for ten days without receiving a test, it gives out one beep every ten minutes. The Midland WR-120 desktop NOAA weather radio knows it is supposed to receive a weekly test from the National Weather Service every seven days. NOTE: If your Midland receiver is beeping, the following explanation is the most common, but it is not the ONLY explanation for a beeping receiver. Broadcasts are found in the VHF public service band at these seven frequencies (MHz): NWR requires a special radio receiver or scanner capable of picking up the signal.

NWR includes more than 1000 transmitters, covering all 50 states, adjacent coastal waters, Puerto Rico, the U.S. Known as the 'Voice of NOAA's National Weather Service,' NWR is provided as a public service by the National Oceanic and Atmospheric Administration (NOAA), part of the Department of Commerce. In conjunction with Federal, State, and Local Emergency Managers and other public officials, NWR also broadcasts warning and post-event information for all types of hazards – including natural (such as earthquakes or avalanches), environmental (such as chemical releases or oil spills), and public safety (such as AMBER alerts or 911 Telephone outages). Working with the Federal Communication Commission's (FCC) Emergency Alert System, NWR is an 'All Hazards' radio network, making it your single source for comprehensive weather and emergency information. NWR broadcasts official Weather Service warnings, watches, forecasts and other hazard information 24 hours a day, 7 days a week. NOAA Weather Radio All Hazards (NWR) is a nationwide network of radio stations broadcasting continuous weather information directly from the nearest National Weather Service office.
