Abstract
A radio paging receiver for receiving a carrier wave modulated paging signal which includes a preamble, an address code and a message, is composed of at least a receiver section, a waveform shaping circuit, a memory section, a control section, a speaker with driving sectionto sound an alert signal and a display section. The memory section stores a predetermined number of received messages, which are counted as they are received by a counter in the control section. The display section under the control of the control section, produces a three part display, the first part being an indication of the age of the displayed message relative to the other messages stored in memory, the second part the call type, when a dual call service is implemented, and the last part one of the messages stored in memory. If a message is being displayed as a new message is received, the previous message continues to be displayed, while the new message is stored in memory if memory space is available. In addition, the receiver operates to change the first part of the display to inform the subscriber that a new message has been received.
