DME HOLD
DME hold is annunciated by splitting the NAV window, as shown in
figure C--12. While in hold, the actual DME can be tuned independent
of the active VOR or ILS.
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.
