Abstract
A digitally controller radio transceiver includes a housing including a front cover provided with a display port; a main controller board mounted within the housing; an optional display board attached to an interior surface of the front cover adjacent said display port, said display board electrically connected to said main controller board by a pressure fit connection; a removable display escutcheon plate mounted on an exterior surface of the cover, overlying the display port; and fastening means extending through the cover and connecting the display board to the display escutcheon plate. Removal or omission of the display board is automatically sensed by the radio transceiver's internal microprocessor which operates accordingly. In one embodiment the transceiver program store may be loaded via an external connector to customize the microprocessor instruction code for the presence or absence of a display.
