Abstract
A radio transceiver comprising a housing including a front cover, a plurality of interchangeable control panels adapted for selective alternative attachment to the front cover, and a plurality of interchangeable keypads adapted for selective alternative attachment to the front cover in underlying relationship with a respective one of the control panels, wherein each control panel is configured for use with a similarly configured one of the keypads. Each of the control panels comprises a relatively thin planar member having front and rear faces and defined by upper, lower and a pair of side edges, and includes a projection or locking bar extending along and away from the upper edge, and fastening means located adjacent the lower edge. A standardized electronic circuit board is provided within the unit, some or all of the switches included on the circuit being accessible, depending on the particular keypad and control panel employed.
