First and second signals are generated (20). Each signal incorporates the prompting message (14, 50) but only one of the signals is compatibly tuned to the display. The first and second signals are alternately provided to the display (52) and the prompting message is legibly displayed when the compatibly tuned signal is provided. The signal that is compatibly tuned to the display is selected (15) in response to the command (60).</p> |
