    Abstract: A radio receiver (40) for receiving an RF signal comprises receiving circuitry (42) for receiving and demodulating the RF signal and a microcomputer (44) coupled to the receiving circuitry (42) for enabling and disabling the receiving circuitry (42) at predetermined times. The radio receiver (40) further comprises an expansion chip (68) coupled to and controlled by the microcomputer (44) for communicating therewith to further process the RF signal. Communication between the microcomputer (44) and the expansion chip (68) occurs at a first speed when the receiving circuitry (42) is enabled and at a second speed faster than the first speed when the receiving circuitry (42) is disabled.

    Abstract: A selective call receiver (100) comprising a receiver (103), a controller (105), and means for presenting a recovered source document (113). The receiver (100) provides a received paging message that was generated from the facsimile message of the original source document, then the received paging message comprising at least one portion of the original source document and an address is interpreted and decoded by the controller. Using the means for presenting (113), the recovered source document can be exhibited in a format that substantially resembles the facsimile message of the original source document

    Abstract: A portable communication device provides user programmable control of addresses to which the portable communication device is responsive as a function of time. The device comprises a receiver, user programmable timing and function control, a memory, a controller, a decoder, and an alerting circuit to provide control of address selection as a function of time, and to alert the user of the selected addresses and messages received during the corresponding programmed time intervals. Control of address alerting priority, receiver operating frequency, and silent mode operation are also provided in conjunction with the user programmed address selection.
