Abstract
An emergency position indicating radio beacon is controlled by an annular switch ring which rotates to ON, OFF, SET, and TEST positions. In the SET position, the buoy transmitter automatically turns on in response to removal of the buoy from a mounting bracket. A light and an audible alarm on the buoy are activated during buoy transmission to alert an operator to the transmission in order to avoid false alarms. The mounting bracket automatically releases and ejects the buoy in an emergency situation in response to ambient water pressure, or the buoy may be manually removed from the bracket for deployment.
