Abstract
A radio pager device includes a display having a zoomed-out multiline mode and a zoomed-in single line mode for display of at least a portion of a series of characters at a time extracted from a message having an address or identification code which is among those from which the pager is authorized to extract message data. The zoom mode is selectable on either a system basis, by default, or a message basis. The message specific zoom mode is determined by accessing display per address information stored in volatile memory and programmable by the user. In the single line mode, continuous horizontal character by character scrolling may be selected by the user and controlled by key actuation to toggle between a stationary paused state and a continuously scrolling state.
