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

key adjacent

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'.
