Abstract

An alerting device, such as a radio pager, which produces an audible alerting signal, in response to a unique identifier received and decoded by said device, incorporates circuitry for periodically reminding the user that a lagging signal has been received. In this context, a short alerting signal or call reminder alert occurs periodically upon cessation of the originating alert and/or message. This method of operation continues until the user manually discontinues it.

Claims

1. A receiver of the type which generates an alerting signal to apprise a user that said receiver has been addressed, comprising:

receiver-decoder means for receiving an encoded address signal, decoding said encoded address signal and detecting if said receiver has been addressed;

initial alert signal generating means, coupled to said receiver-decoder means, for generating a periodic initial alert signal when the address of said receiver is detected, said initial alert signal being generated during a first period of time and

reminder audio alert signal generating means, coupled to said receiver-decoder means, for generating a periodic reminder audio alert signal commencing when a predetermined amount of time has elapsed after the cessation of said initial alert signal, said remidner alert signal being periodic at a different rate than said initial alert signal.

2. A receiver of the type which generates an alerting signal to apprise a user that said receiver has been addressed, comprising:

receiver-decoder means for receiving an encoded address signal, decoding said encoded address signal, and detecting if said receiver has been addressed;

initial alert signal generating means, coupled to said receiver-decoder means, for generating an initial alert signal when the address of said receiver is detected, said initial alert signal being generated during a first period of time, said initial alert signal including a plurality of audio bursts during a first predetermined period of time, the occurrence of said bursts being periodic at a first predetermined rate; and

reminder audio alert signal generating means, coupled to said receiver-decoder means, for generating a reminder audio alert signal including a plurality of audio bursts, the occurrence of the audio alert signal including a plurality of audio bursts, the occurrence of the audio bursts of said reminder alert signal commencing when a predetermined amunt of time has elapsed after the cessation of said initial alert signal, and being periodic at a second predetermined rate substantially less than said first predetermined rate.
