We offer a wide range of products that meet various

Others

The emergency broadcast radio was born in 1999 in response to a requestfrom a local government for a low-cost, popular version of the home-type
receiver for the emergency municipal radio communication system,
which had been expensive until then. In
recent years, not only earthquake early
warnings but also information on guerrilla
downpours, landslide warnings, and flying
object launches is broadcast.
