In normal VOR/ILS/DME operations, one of the six DME channels is
paired with the active frequency and another with the preset frequency.
Pushing the DME function key splits the NAV box on the main tuning
page and the active DME channel can be selected separately from the
active VOR/ILS frequency.
Cycling the DME select button sequences the NAV window, as
described in table C--2.
