CONTROL UNIT

The Control Unit is a pedestal-mounted interface allowing data entry, COM and NAV tuning, and transponder
control. Many procedures can be performed using the Control Unit rather than the MFD/PFD display bezel
controls. Annunciators above the FMS, XPDR, NAV, and COM keys are illuminated when their respective
control modes are selected.
COM and NAV radio tuning can be accomplished from the control unit. The appropriate frequency box on
the selected display is outlined by a light blue selection box, which flashes for a few seconds to indicate control
unit activity. Selection of a different display control or radio tuning mode results in cancelation of the previous
radio tuning mode.
