For option c the receiver will indicate Autoscan starting after the Wait Lock
period has elapsed by displaying Autoscan on the top line of the LCD
display. Once it has found an appropriate signal the receiver should display
the RECV indicator with the signal strength indicated by a bar graph
display.
