45MR00609 ABSTRACT Different digital radio transceiver front panel escutcheon plate assemblies are provided for different optional transceiver configurations. A digital signal controller which is part of the main transceiver circuitry is capable of performing any of various basic and option functions under control of program control instructions stored in an associated non-volatile memory. Subsets of those features are selectively disabled by irreversibly modifying the transceiver unit from the outside of the unit (e.g., by cutting certain PC board pathways through holes provided in the transceiver unit front panel). The controller enables (executes) portions of the program control instructions stored in its associated non-volatile memory and disables (does not execute) other portions of the stored program control instructions in response to detection of continuity/discontinuity over those certain pathways.
