Nav Radio (VOR)
Press VOR to activate control of the internal Nav Radio. All other func-
tions will continue to function normally, such as active flight plans.
Note that distances, such as to a Localizer, are based on calculated
distances from GPS information.
ID
Press the ID key to toggle the Nav audio between Off, On and Voice
only. The On selection is indicated by ID replacing the ACT annunciator
to the left of the Active frequency and pressing the ID key so ID is high-
lighted. The Voice selection is indicated by VOX replacing the ACT
annunciator to the left of the Active frequency. The ID function label
will be partially highlighted when Voice is selected and fully highlighted
when On is selected. The Monitor function is turned off when any ID
mode is active.
Monitor (MON)
Press the MON key to toggle the Nav channel monitoring function.
When monitor mode is active, a MON annunciator will appear on the
left side of the standby frequency, the standby radial replaces the
active identifier, and the MON function label will be highlighted.
Frequency monitoring allows you to listen to the Standby VOR fre-
quency while the CNX80 monitors the Active frequency for activity.
When Active frequency receives a signal, you will hear the Active fre-
quency until its activity stops. Pressing MON will be ignored for ILS fre-
quencies. If Voice or ID functions are active, the Nav radio will
temporarily turn off the ID function until the Monitor function is turned
off.
Recall (RCL)
1. Press the RCL key to bring up a list of the last eight VOR/ILS fre-
quencies used as the Active frequency.
2. Turn the Large knob to highlight a frequency.
3. Press the <SBY or <A> keys to insert the frequency.
4. Press the VOR key again if no choice is desired.
Flip/Flop
Press the <-> (flip/flop) key to swap the Active and Standby frequen-
cies.
