The available airports can be scrolled through using the large frequency select
knob. The individual frequencies associated with that airport can be scrolled
through by using the smaller frequency select knob. After you have stepped
through all the loaded airports, or if there is no GPS attached, the built-in
memory of the controller will be displayed.
In each case the selected frequency is loaded into the standby position.
Pressing MEM again leaves the stored frequency in the standby window.
Pressing the Flip-flop button loads the stored frequency directly into the active
channel.
Note: When the controller is displaying the available airport
frequencies it will not accept any new updates from the GPS to avoid
the frequencies changing during selection. To allow the GPS to
update the available frequency database you must come out of
memory mode by pressing the MEM or flip-flop button.
Frequency Memory
If no GPS is connected and the MEM button is pressed, or if the large knob is
rotated beyond the remote database the controller will access the internal
quick reference memory. There are 9 quick reference memory locations and
the bottom edge of the screen will display which memory location is currently
selected (1
– 9).
Rotating the small frequency selector knob will step through the memory
locations. The standby frequency window will display the stored frequency.
To store a frequency in one of the memory locations it must first be tuned and
active as the primary frequency. Press MEM to enter the memory mode in the
usual way. Select the channel you want to overwrite with the tuning knobs.
