Abstract
Abstract A paging receiver is provided having an information setter that includes a memory device for storing call numbers assigned the receiver to enable it to determine when it has been individually selected by a radio paging message. In addition to the call numbers, the memory device also stores receiver performance information which selects which of several possible means are used to indicate that a message has been received. A decoder, preferably in the form of a microprocessor, stores information contained by the information setter in a separate register or memory device contained in the decoder. Once the information has been read from the information setter into the decoder it effects control of the receiver's receiving operation, as well as the receiver's selective response to paging messages.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
140 words
A paging receiver comprising: an antenna; a radio unit for demodulating a radio signal received by said antenna; an information setter storing information that designates an individually assigned call number; a decoder supplied with the output of said radio unit; and a plurality of informing devices which make reports to a user of said receiver in accordance with decoder outputs; said information setter comprising a first memory device storing said information designating said individually assigned call number and information designating the selection of functional options of said receiver including the selection of which of said informing devices make reports to said user; and said decoder including a second memory device for storing information stored in said information setter, enabling said decoder to process the output of said radio unit in accordance with the information stored in said second memory device.
Claim 2
Dependent Claim
140 words
A paging receiver comprising: an antenna; a radio unit for demodulating a radio signal received by said antenna; an information setter storing information that designates an individually assigned call number; a decoder supplied with the output of said radio unit; and a plurality of informing devices which make reports to a user of said receiver in accordance with decoder outputs; said information setter comprising a first memory device storing said information designating said individually assigned call number and information designating the selection of functional options of said receiver including the selection of which of said informing devices make reports to said user; and said decoder including a second memory device for storing information stored in said information setter, enabling said decoder to process the output of said radio unit in accordance with the information stored in said second memory device.
Claim 3
Dependent Claim
77 words
The receiver according to claim 1 wherein said functional option selection information comprises automatic reset performance information for terminating said reports after a predetermined time, memory performance information for temporarily storing received radio signals, display performance information for displaying messages contained in the received radio signal, information for displaying with light said reports, vibration performance information for informing the user of said reports by vibrations or information for informing the user of the reports by tone production.
Claim 4
Dependent Claim
14 words
The receiver according to claim 1 or 2 wherein said decoder comprises a microprocessor.
Claim 5
Dependent Claim
66 words
The receiver according to claim 1 wherein said information setter comprises a plurality of input/output terminals connected between said decoder and said information setter for reading out information from said information setter, at least one of said input/output terminals also being used to send out device control signals the information read out from said information setter and said device control signals being sent at different times.
Claim 6
Dependent Claim
17 words
The receiver according to claim 4 wherein said device control signals are supplied to said informing devices.
Claim 7
Dependent Claim
19 words
The receiver according to claim 4 wherein one of said device control signals is supplied to said radio unit.
