ABSTRACT:
A novel pager allows the input and transmission of a virtual unlimited range of messages. The pager has a character dial on the periphery of which are printed the letters of the alphabet and digits 0 to 9. A rotary encoder encodes the movement of the dial. When a selection key is pressed, the character showing through a window in the housing of the pager is selected and entered. When the message is completed, the pager may transmit the message to a paging system by radio transmission to a base station or by emitting a series of sounds in which the message is encoded. In the case of emitted sounds, the sounds are conveyed along an open phone line to the paging system where they are decoded.
