TRUE and MAGNETIC POSITION
Most
navigators realize there is a difference between true and magnetic
north. True north is the
top
of the world. It's
where all lines of longitude
converge. Magnetic north is the location our compasses point. It lies
several hundred miles to the south of true north, at a location
in Canada.
Charts are usually laid out according to a Mercator projection which
uses true north. If you plot a course on a chart using the Mercator
projection, you'll either have to convert magnetic readings to
true or use
true readings.
The Z-9500 can display navigation information in magnetic or true.
When ft's turned on for the very
first time, magnetic
is used. To switch
to true, press the MENU key, then press the key adjacent to the
"CHANGE SETUP" label. Now
press the
key adjacent to the "MORE"
label. The menu shown above appears. In this example, magnetic is in

navigation information in degrees true. Repeat these steps
to switch
back to magnetic. The menu now reads "Show
Mag. Brgs."
FULL AND SUMMARY DATA MODES
The Position, Navigation, and Steering displays show their information
in one of two
ways, either full or
summary. The full data mode shows all
information available for that display
in small letters and numbers. The
summary data mode shows
a partial list of the data in large letters and
numbers. The summary
data mode doesn't show as much information
as the full data mode, but ft's easier to read due to the larger
characters.
The Z-9500 is in the full data mode when ft's first tumed on or after a
preset.
To switch between the full and summary data modes, first press the
MENU key. Now
press
the key next to the "More" label. Finally, press
the
key adjacent
to the "Turn Summary On". This switches all three
displays at the same time. To return to the full data mode, repeat the
above
steps. The menu now reads "Turn Summary Off'.
