1. A selective call receiver for receiving and displaying transmitted coded message signals on a plurality of channels, said coded message signals including channel identification information identifying a source of transmission for each of said plurality of channels, said selective call receiver comprising:
- detecting means for detecting transmitted coded message signals;
decoding means responsive to said coded message signals for decoding said channel identification information;
memory means containing a table including the channel identification information identifying each source of transmission for each of the plurality of channels, and further containing displayable location indicia corresponding thereto, and predetermined channel identification information identifying at least one predetermined channel;
channel selecting means responsive to said decoding means for selecting the at least one predetermined channel when said decoded channel identification information is the same as said predetermined channel identification information, and further for selecting a second channel of the plurality of channels when said decoded channel identification is different than said predetermined channel identification information;
comparison means, coupled to said memory means and said decoding means, for detecting identity between the decoded channel identification information and said stored channel identification information for identifying the transmission source on the selected channel in response thereto; and
interrogation means, coupled to said comparison means, and accessible to the receiver user to cause the receiver to display said location indicia corresponding to the channel identification information received on the selected channel, thereby positively identifying the source of the coded message signal transmission.

Abstract
A selective call receiver for receiving and displaying information in a nationwide communication system includes circuitry to decode and process transmitted channel identification information. The receiver displays channel identification indicia in response to a user interrogation thereby confirming proper operation of the receiver on the system at the expected location.

12. A selective call receiver for receiving and displaying transmitted coded message signals on at least two channels, said coded message signals including channel identification information identifying a source of transmission for each of the channels, said selective call receiver comprising:
-
detecting means for detecting transmitted coded message signals; decoding means responsive to said coded message signals for decoding said channel identification information; memory means containing a table including the channel identification information identifying the source of transmission for each of the channels, and further containing alphabetic location indicia corresponding thereto, and predetermined channel identification information identifying at least one predetermined channel; channel selecting means responsive to said decoding means for selecting the at least one predetermined channel when said decoded channel identification information is the same as said predetermined channel identification information, and further for selecting a second channel when said decoded channel identification information is different than said predetermined channel identification information, said channel selecting means further including timing means generating a periodic receiver time interval during which said channel identification information must be repetitively decoded and compared; comparison means, coupled to said memory means and said decoding means, for detecting identity between the decoded channel identification information and said stored channel identification information for identifying the transmission source on the selected channel in response thereto; and interrogation means coupled to said comparison means, and accessible to the receiver user to cause the receiver to display said alphabetic location indicia corresponding to the channel identification information received on the selected channel, thereby positively identifying the transmission source of the coded message signal transmission. - View Dependent Claims (13)
