B. PFD Soft Keys
The soft keys are located along the bottoms of the displays below the soft key labels.
The soft key labels shown depend on the soft key level or page being displayed. The
soft keys can be used to select the appropriate soft key function.
When a soft key is selected, its color changes to black text on gray background and
remains this way until it is turned off, at which time it reverts to white text on black
background. When a soft key function is disabled, the soft key label is subdued
(dimmed). Soft keys revert to the previous level after 45 seconds of inactivity.
CDI The CDI soft key toggles between the selection of GPS or
VOR/LOC as the active navigation source.

keys.

4.3 MFD Knobs and MFD Soft Keys
The MFD controls are on the right side of the GDU 620 unit, next to and beneath the
MFD display. The rotary knobs scroll through various page groups and pages of the
MFD and manipulate data and settings by pressing the knob to activate a cursor.
Soft keys at the bottom of the display allow for some quick functions to be performed on
each page. The soft keys operate by press and release. More detailed configuration is
typically available by pressing the MENU button, which is on the right side of the display.
Pressing and holding down the CLR key is a good way to
get back to the main map page
on the MFD. This can be
used as a quick way back, or when the pilot has selected a
submenu within the system.
