Abstract
A system and method for indicating to a user that an operable-connection or non-operable connection has been made between a portable radio and a vehicle kit forming a mobile communication system. The system determines if an operable-connection has been made by determining if a hands-free-request signal, an external power signal, and an external antenna signal are present. Detection of the hands-free-request signal, external power signal, and external antenna signal are indicative that the portable radio and vehicle kit are operably connected such that the mobile communication system is fully operational. An operable-connection alert indicative of an operable connection between the portable radio and vehicle kit is generated by a radio display and an external speaker in response to a determination that the hands-free signal, external power signal and external antenna signal are present. In the preferred embodiment, the external antenna signal is determined by either comparing a measured received signal strength indicating (RSSI) with a reference RSSI value or detecting an increase in RSSI after inserting the portable radio into the cradle of the vehicle kit.
