Sound radiating structure includes a plurality of pipes each defining an inner cavity along the length of the pipe. Mounted on the front surface of the base unit is a transversely aligned LED tube. This in turn equates to a reduced incidence of failure in the electron shield. The input controller provides a plurality of serial input signals. The processing unit is configured to interface location information from the location provider, payment information and order information from the customer identification card, through the remote connector, to place an order for inventory at the inventory order interface. Unlike a conventional wireless receiving device, a digital signal from an AD converter is directly supplied to the AGC processing portion, without passing through an FIR filter.
