Abstract

Paging receiver including a memory for a predetermined address code, a comparator to determine the equality between this address code and a received address code and a message coding device cooperating with a display to represent a received message code, the memory being free-programmable from the exterior to store therein at least one desired selectable address code which may be represented on the display.

Claims

1. A programmable paging receiver comprising:

address memory means that are freely programmable from exterior of said receiver, for storing therein at least one desired programmable address code used to select that particular receiver;

comparator means for comparing the programmed address code and a received address code, to determine whether that particular receiver is to be selected in response to the received address code;

meas for receiving and processing programming signals for changing the stored address code;

a display device; and

message coding means cooperating with the display device to represent on the display device a received message code and an address code, whereby the address code used to select that particular receiver may be variably programmed, and the programmed address code verified on the display device.

2. The receiver of claim 1 wherein the address memory means are non-volatile.

3. The receiver of claim 1 further including contact means for receiving said programming signals for changing the stored address code.

4. The receiver of claim 1 wherein said receiving and processing means further includes means for receiving and processing electromagnetically transmitted programming signals.

5. A container installation accomodating a number of paging receivers as claimed in claim 1 including means for converting a desired address code into a binary code and means for selectively transferring this address code to the freely programmable address memory of a selected paging receiver.

6. The container installation of claim 5 further including a display for displaying the address transferred to a selected paging receiver.
