A cordless telephone set advantageously includes a wireless test mode accessible by a user for evaluating performance levels of operating parameters in the cordless telephone set in diverse geographical locations. When configured in a normal operating mode, the cordless telephone set provides normal wireless communications. When configured in the wireless test mode, the cordless telephone set provides audible and visual input to its user for use in determining a maximum acceptable separation distance for satisfactory communications between a telephone handset unit and its associated base unit in the cordless telephone set. This operating range determination for the cordless telephone set is achieved by providing a simulation of a recognizable tone, such as dial tone, to which a user subjectively listens while testing an application environment. At the same time, statistical readings of signal strength and voice quality also are provided in a display on the telephone handset unit while in this wireless test mode. The simulated tone and the statistical readings allow the user to quickly and easily correlate effective, usable operating range for the cordless telephone set.
