ABSTRACT:
A continuous radio announcer device capable of transmitting a stored sound message in digitized format at predetermined time intervals. The radio announcer device includes a central unit and a remote unit that can be remotely accessed and the sound messages are stored in memory. The remote unit is a stand along device that can also be programmed on site. If remotely accessible, a modem and associated coded signals need to be provided to effect the communication over the public telephone network or through a wireless transmission. The amount of stored information will depend on the size of the memory.
