MFD/PFD CONTROL UNIT
The optional MFD/PFD Control Unit is a pedestal-mounted interface allowing MFD/PFD1 operation, data
entry, COM and NAV tuning, and transponder control. The MFD/PFD Control Unit duplicates many PFD
display bezel controls. PFD2 is not controlled by the MFD/PFD Control Unit. Annunciators above the
PFD
,
MFD
,
NAV
, and
COM
keys illuminate when their respective control modes are selected. The unit is in MFD
control mode by default on system power-up.
Tune the COM and NAV radios in either MFD or PFD control mode. 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 cancellation of the previous
radio tuning mode.
