WARNING: If ‘User MV’ is selected, you
must periodically update the magnetic
variation as your position changes. Using
this setting, the NavTalk Pilot will not
automatically calculate and update the
magnetic variation at your present position.
Failure to update this setting may result in
substantial differences between the
information displayed on your unit and
external references, such as a magnetic
compass.
Distance & Speed— lets you select the desired units
of measure for distance and speed readouts in ‘Nautical’,
‘Statute’ or ‘Metric’ terms.
The ‘User Map’ option
allows you to define the
magnetic variation for
your area. ‘Auto MV’
is the preferred setting
in most cases.
Select nautical, statute
or metric units of
measure from the
‘Units’ settings.
