Abstract
A data communication receiver (100) for operating in a demonstration mode comprises a receiving circuit (110) for receiving and decoding radio frequency signals, a battery (140) for powering the receiving circuit (110), and a display (150) for displaying information. A switch (142) coupled between the battery (140) and the receiving circuit (110) disconnects the receiving circuit (110) from the battery (140) to disable the receiving circuit (110) when a signal has been received indicating that the data communication receiver (100) is to operate in the demonstration mode. A demonstration element (165, 170) coupled to the display (150) provides at least one demonstration screen to the display (150) in response to the disabling of the receiving circuit (110).
