"AUTO" position indicates a Doppler speed
(SDME) but if the DS-80 fails, a GPS speed
will be indicated.
Note 1: If the log speed fails, the display
unit reads a GPS speed, but speed data will
not be output to other equipment.
Note 2: Doppler speed is used to calculate
speed when both DOPPLER and GPS are
abnormal in AUTO.
