Abstract
Abstract A pager has a display and a selectively activated light for illuminating the display. The illumination of the display is accomplished using a minimal number of components thereby reducing the size and cost requirements of the pager. The method of message sequencing and the illumination of the pager display is controlled solely by the pager user through a single switch.
