OPERATION
3.1 GENERAL
The radio tuning philosophy used on the display is based on an association between the
tuning controls (knobs and buttons) and a graphical cursor that appears in the PFD tuning
window.
tuning controls (knobs and buttons) and a graphical cursor that appears in the PFD tuning
window.
Normally, the cursor is a cyan box that surrounds the frequency, code, or mode being
controlled. The pilot positions the cursor by pressing the display bezel soft key located
adjacent to the desired data field or by pressing a window focus shortcut control key on
the MF Controller (MFC). For example, if the soft key adjacent to the NAV 1 tuning field
on the pilot's PFD is pressed the cyan box cursor will move to the NAV 1 standby
frequency field on that display. When the MF Controller is used the 'window focus' will be
on the radio window indicating control is possible through the MF Controller and the
joystick is used to move the cursor to the desired field.

The text is shown in the larger font size to enhance visibility while tuning. One second after
the controller activity stops, the cursor reverts to the smaller font, but remains on the
standby frequency field. Twenty seconds after the controller activity stops, the cursor
defaults to the onside VHF COM standby frequency field as a cyan box.

3.2 RADIO TUNING WINDOW
The Radio Tuning window is in the lower right hand corner of the pilot's PFD and the lower
left hand corner of the copilot's PFD. The cyan box surrounding the Radio Tuning window
shows that the display focus is on the radio tuning, and the MF Controller can be used to
control some of the radio functions. The cyan outline on the soft key identifier indicates
the radio that any inputs will affect. The Very High Frequency (VHF) Communication
(COM) tuning sub-window(s) are the first line(s) of the displayed radios, then the VHF
Navigation (NAV) sub-window(s) and the Automatic Direction Finder (ADF)
sub-window(s).
