Abstract
An Emergency Vessel Location System (EVLS) which broadcasts a verbal MAYDAY message including the vessel or vehicle identification number (VIN) and the vessel position via a transceiver controlled by the EVLS is provided with a verbal scrolling technique to initially load a VIN number into the EVLS. The verbal scroll entails annunciating letters of the alphabet and then numbers one at a time. In one embodiment programming is performed by two switches, one a TEST switch on the microphone, although any two switches may be used singly and in combination to enter the VIN. One switch is used to advance the scroll, while the other is used to select an entry.
