When shopping for a severe weather alert radio, it is recommended that you look for models with the Public Alert and/or the NOAA Weather Radio (NWR) All Hazards logo. The Public Alert Standard (CEA-2009-A) was developed by the Consumer Electronics Association in conjunction with the National Weather Service (NWS).
Devices carrying the Public Alert logo meet certain technical standards and come with many, if not all, of these features: alarm for audible alerting; SAME technology for specifying a particular area to receive alerts; battery backup; jack for connecting optional accessories, such as a strobe light or bed shaker for people who are deaf or hard of hearing.
