Abstract

The process of the present invention alerts a radiotelephone user when the portable is not connected to the power booster/antenna extender system. By checking for a connect signal from the radiotelephone, the system knows the portable is missing and alerts the user, thus enabling the user to install the portable before driving off without it.
