configured to CVR, to HIGH speed or assign the CVR

NOTE 1: If an MCDU is wired and configured as an ARINC 739A MCDU, which does not display
graphics, a low-resolution MFD-640 or a high-resolution MFD-640/EFI-890R must also be
configured in order to display graphics. If an MCDU is wired and configured as a UASC FMS
CDU, the MCDU is able to receive graphics and, therefore, no other device is necessary to
display graphics.
NOTE 2: A low-resolution MFD-640 and high-resolution MFD-640/EFI-890R are configured on the
GRAPHICS setup page in the appropriate CDU n GRAPHICS DISP ON field(s).
NOTE 3: The SQP threshold is the difference between the SQP of the currently tracked ground station
and the value of the SQP of another ground station necessary to initiate a handoff.
