This invention allows radio users and service per- sonnel to make in-the-field adjustments to a controlled set of radio parameters without the use of a domputer. Examples of such radio parameters might include squelch, display contrast, RF power, deviation, and min- imum and maximum volume settings. The adjustment of certain parameters (power, deviation etc.) would only be made available to qualiied service personnel to pre- vent possible FCC violations. It is suggested that this be achieved through the use of a hardware "key" that could be attached to the side connector. Only when this key was attached would g parameters be accessible for adjustment.
