1. A method of calibrating transmission circuitry of an installed communication unit, comprising the steps of:

  • interrupting routine operation;

    generating a driving signal at a first level which drives a circuit element into saturation;

    measuring a first signal power level produced by said circuit element;

    setting said level of said driving signal to a second level that is lower than said first driving signal level;

    measuring a second signal power level produced by said circuit element;

    comparing said first signal power level to said second signal power level; and

    if said second signal power level is less than said first signal power level by more than a predetermined amount, using said second driving signal level as a maximum drive level for said circuit element upon resuming routine operation.
