Abstract

Abstract A radio call receiver can be disabled by its rightful owner when it is lost or stolen. When a radio call receiver 100 receives a radio selection call signal, a decoding section 30 decodes the received data and transmits it to a control section 40. The control section 40 obtains a unique ID code and an additional address from the received data. An ID code determination section 43 compares the unique ID code to the registered ID code stored in an ID-ROM section 51. If they match and there is an additional address included in the signal, a password comparison section 42 compares the additional address to the registered password. If they match, the control section stops the functions for receiving the message in the call signal and displaying the received message.

Claims Analysis

Total Claims: 13
Claim 1
Independent Claim 72 words
A radio call receiver for displaying a message comprising: a decoder for decoding a received radio selection call signal to detect an ID code, a password and a message; a memory for storing a registered ID code; and control means for (a) comparing said detected ID code to said registered ID code, (b) comparing said password to a preset password, and (c) disabling said receiver if said two passwords are the same.
Claim 2
Dependent Claim 32 words
The radio call receiver as claimed in claim 1, wherein said control means prevents said registered ID code from being read from said memory when said two passwords coincide with each other.
Claim 3
Dependent Claim 27 words
The radio call receiver as claimed in claim 1, wherein said control means prevents said message from being displayed when said two passwords coincide with each other.
Claim 4
Dependent Claim 17 words
The radio call receiver as claimed in claim 1, wherein said control means stores said preset password.
Claim 5
Dependent Claim 16 words
The radio call receiver as claimed in claim 1, wherein said memory stores said preset password.
Claim 6
Dependent Claim 33 words
The radio call receiver as claimed in claim 1, wherein said control means further comprises means for disabling said receiver when no input operation has been performed for a predetermined period of time.
Claim 7
Dependent Claim 22 words
The radio call receiver as claimed in claim 1, wherein said control means disables said receiver when a battery has been replaced.
Claim 8
Dependent Claim 17 words
The radio call receiver as claimed in claim 1, further comprising means for entering said preset password.
Claim 9
Dependent Claim 34 words
The radio call receiver as claimed in claim 1, wherein said control means further comprises means for restoring normal operation of said receiver responsive to input of said preset password via said entering means.
Claim 10
Dependent Claim 66 words
A receiving method of radio selective call signal, comprising the steps of: decoding a received radio selection call signal to detect an ID code, and a message; comparing said ID code to a registered ID code; checking whether a password added to said ID code has been received; comparing said password to a preset password; and disabling said receiver when said two passwords are the same.
Claim 11
Dependent Claim 24 words
The receiving method as claimed in claim 10, further comprising the step of: preventing any stored message from being displayed after said disabling step.
Claim 12
Dependent Claim 22 words
The receiving method as claimed in claim 10, further comprising the step of: displaying information about an owner after said disabling step.
Claim 13
Dependent Claim 29 words
The receiving method of radio selective call signal as claimed in claim 10, further comprising the step of: restoring operation of said receiver upon input of said preset password.
