In the wake of January's false nuclear missile warning in Hawaii, the FCC is looking to improve the reliability of its Emergency Alert system. Now authorized state and local officials can conduct "live code" tests of the system, which use the same alert sounds and processes as an actual emergency would. The idea is to help train local officials in using the alerts, as well as teaching members of the public how to respond to real alerts. These tests are required to be coordinated, planned, and come with disclaimers.
